Abstract
In a process for producing detergent particles comprising an anionic surfactant, a paste comprising water and the surfactant is fed to a drying zone where it is heated. Subsequently, the paste is cooled in a cooling zone. A layering agent is introduced into the cooling zone to improve granularity.
Description
The present invention relates to anionic detergent particles, its production method and the composition that contains detergent particles.More particularly, the present invention relates to the production method of the high detergent particles of anionic surfactant concentration, this method is to contain the washing composition mashed prod drying of anion surfactant, and relates to the detergent particles that obtains thus.
Usually the detergent active compound that adopts in detergent composition comprises anion surfactant, as linear alkylbenzene sulfonate (LAS), straight chained alkyl ether sulfate (LES) and primary alkyl sulphates (PAS), and nonionogenic tenside are as ethoxylated alcohol.For improving the de-sludging performance, preferably supply with the powder of high-content detergent active material.
Usually, the high-content of the active substance that can mix is limited by the requirement of production method.The detergent composition that tap density is high, its typical production method are all components of said composition and/or the matrix powder that for example obtained by spray-drying process are mixed mutually or to granulate, and compare with the composition that tap density is low, and this brings very big benefit to the human consumer.
It is known that detergent active compound is joined in this liquid detergent compositions.But because ratio that must control liquid phase and solid phase is with the formation detergent particles, so the high-content of the detergent active material that can add like this is conditional.Also having known can be with anion surfactant, and for example LAS or PAS join in the detergent composition by the mode of solid auxiliary, are about to contain other composition of this tensio-active agent and said composition, as the particle adding of yellow soda ash and washing assistant.Up to now, owing to good flowability need be provided and reduce poly-group tendency, the amount of the anion surfactant in this auxiliary is restricted always.
EP-A-506 184 announces a kind of liquid acid precursor substance successive drying neutral method with anion surfactant.Can prepare the detergent particles that activated detergent content is 30-40% (weight) with this method.
A kind of method of producing Powdered anion surfactant of EP-A-572 957 announcements: the aqueous slurry that contains 60-80% solid tensio-active agent is delivered in the vaporizer, formed dry and concentrated these slurries of layer of surface promoting agent film and one side on the reactor wall, simultaneously from wall, it scraped.
What disclose in EP-A-572 957 also has: the reactor wall temperature is 50 to 140 ℃; The highest wall temperature of embodiment is 130 ℃.It is said that higher temperature can cause thermal destruction and tonal variation, is disadvantageous therefore.And document disclosure, the point of a knife speed of scraper preferably 2 arrives 20m/s in the reactor, and the highest point of a knife speed of embodiment is 10.5m/s.Disclosed tap density is up to about 0.5g/cm

Yet, opposite with above-mentioned saying, as described in our No. 95/03321, PCT patent application PCT/EP (not delivering before preferential day) in present patent application, the good detergent granules of tap density height, anionic surfactant concentration height and powder property can be with following method production: heating contains the mashed prod of this tensio-active agent in comparatively high temps first area uniformly, then the particle of such formation is cooled down.
In general, aforesaid method comprises: contain water (its amount generally greater than mashed prod weight 10%) and the mashed prod of anion surfactant send into drying zone, this pasty substance of heating then cools off in the cooling zone to form detergent particles to reduce water-content in drying zone.
The method of describing in our the undocumented patent application is particularly suitable for the anionic detergent component as detergent particles with PAS.Regrettably, the amount of PAS is many more in anionic group, and detergent particles just tends to form viscous surface more, and for the requirement that final production goes out the particulate product of uniform drying, this is very deleterious.
Have been found that now a stratification agent introducing cooling zone just can address this problem.
EP-A-390 251 discloses, and when producing detergent particles, available stratification agent is as the granulating auxiliary, and wherein all components are handled in homogenizer, keeps in moderate speed's stirrer then or enters deformation stage.
Therefore, a first aspect of the present invention is to propose the method that a kind of production contains the detergent particles of anion surfactant, this method comprises following step: the pasty substance that contains water and anion surfactant is delivered to drying zone, the heating pasty substance is to reduce their moisture in drying zone, then the cooling pasty substance is characterized in that in cooling step the stratification agent being incorporated in the cooling zone to form detergent particles in the cooling zone.
Without the stratification agent, the pasty substance that adopts cooling gas to handle in the cooling zone also can reach same effect.Therefore, a second aspect of the present invention is to propose the method that a kind of production contains the detergent particles of anion surfactant, this method comprises following step: the pasty substance that contains water and anion surfactant is delivered to drying zone, the heating pasty substance is to reduce their moisture in drying zone, then in the cooling zone, cool off pasty substance, to form detergent particles, it is characterized in that with the pasty substance in the cooling draught processing cooling zone.
Cooling gas needs drying in general, for example can be air or nitrogen, for example below 0 ℃.This cooling gas can the counter-current flow mode use.
But the present invention is not limited only to the composition that anionic group contains LAS or is made of LAS.Comprise the situation of other anionic group of PAS or LES for employing, the present invention also is very useful.
The stratification agent can be anyly can give the particle coating to improve the material of its granularity at cooling stages.For this reason, preferably inactive relatively material reaches this purpose, and particularly any has the inert material of good result in washing soln, for example, and silico-aluminate, silica mica and clay.Can use these mixtures of material.Hereinafter will narrate the example of silico-aluminate and silica in more detail.This material is not got rid of this material as the coating of finished particle and is existed in this particulate body yet.
The consumption of coated fertilizer is with respect to the ratio of the total amount of this other material of particulate in cooling stages, and preferably 1: 3 to 1: 20, further preferred 1: 9 to 1: 20.
Drying zone can be chosen wantonly under rough vacuum to help to remove moisture and volatile matter.Vacuum can be high to normal atmosphere from 100 Torr, and very big production method handiness is provided like this.But, cross 500 Torr and help when vacuum operating is provided, reducing investment to atmospheric vacuum.
Stirring material can ensure control and the increase output to residence time and granular size in drying zone and/or cooling zone.
This method is preferably carried out continuously, because this is convenient to carry continuously detergent particles.In continuous processing, the flow velocity of mashed prod with 10 to 25kg/m
2/ hr the order of magnitude is advisable, and preferred 17 to 22kg/m
2/ hr, for example 20kg/m
2/ hr.
Average retention time is to be advisable less than 5 minutes in drying zone.The preferred especially residence time is less than 4 minutes, and the most preferably short as far as possible residence time decomposes the possibility of (particularly PAS) and increases product production to greatest extent reducing.
In general, mashed prod will provide the inner net heat of mashed prod to shift in the stirring heating district, thereby help removing moisture.Stirring can reduce the duration of contact between pasty state particle and the drying zone wall, adds that effective heat shifts, and just can reduce " hot spot " that may cause decomposing and form possibility.In addition, drying process is improved, and this just can make, and residence time shortening/output increases in the drying zone.
For PAS, for avoiding thermolysis, preferred pasty substance heating is no more than 170 ℃.
Method of the present invention makes might form the tap density height, for example surpasses 550g/cm
3Particle.
At the cooling zone internal cooling, its service temperature that is fit to is no more than 50 ℃, preferably is no more than 40 ℃, as 30 ℃ paste-like material.Be preferably in have in the cooling zone stir so that wherein material effectively cool off.Compare with previous public technology, the employing particle initiatively cools off, and can reduce owing to particle is heated to comparatively high temps the pyrolysated possibility to occur, and can reduce particulate viscosity.This active cooling can be by (for example the using cooling jacket) of surrounding cooling zone cold water or realize through the circulation of refrigerative water (the ethylene glycol water about as-5 ℃) for example.
Preferred pasty substance contains the mixture of anion surfactant and water, though if having a mind to add or from upstream process, for example bring into also as impurity in the production of tensio-active agent and may have other component.Preferred pasty substance contains at least 60% (weight), and more preferably at least 65%, the especially preferred anion surfactant of at least 70% (weight).Correspondingly, mashed prod contains and is no more than 50% and preferably be no more than the water of 30% (weight).The temperature of pasty substance when being admitted to drying zone should be that available pump is smoked, and this may limit the maximum of the tensio-active agent that wherein exists.
When anionic agent contained PAS, correspondingly mashed prod should be sent into drying zone under 50 ℃ to 70 ℃ temperature, preferred 50 to 65 ℃.
Method of the present invention can be implemented in any suitable device.But preferably use the scraping surface moisture eliminator, particularly the quick response device.Suitable quick response device for example comprises the dehumidification system rapidly that can buy from VRVSPAProcessi Impianti Industriali company.The drying zone heat transfer area generally is 3: 1 to 1: 1 with the ratio of cooling zone heat transfer area, for example about 2: 1.
Can optionally before the cooling zone, select to adopt two or more drying zones when needing.Can adopt individual equipment as required with drying zone and cooling zone are provided, perhaps change a kind of method, also the equipment that can adopt moisture eliminator and cooling bed to separate.
Suitable drying zone cross section is circular substantially, and therefore, it is limited by columniform wall.Preferred above-mentioned wall heats with the heating jacket that can inject water, steam or oil.Described wall is inner preferably to keep at least 130 ℃, particularly at least 140 ℃.The vaporator rate of preferred drying zone is every m
2Heating surface per hour 3 arrives 25kg water, and particularly 5 to 20kg water.
Preferred cooling zone is limited by cylindrical wall.When production process is carried out continuously, be suitable for equipment drying zone and cooling zone horizontal aligument arrangement substantially, to help efficient drying, cooling and drying and cooling zone conveying material on the cardinal principle horizontal direction.
Correspondingly, drying zone and preferred cooling zone have stirring tool that the tensio-active agent mashed prod by aforementioned region and shaped particles are stirred and carry.Stirring tool is one group of blade and/or scraper that axially is installed in the circumferentially extending in the rotating shaft preferably.Blade and/or scraper preferably tilt with effective conveying material, and preferably the gap with inwall is not more than 10mm, for example 5mm.
We find that the present invention is specially adapted to produce the high-quality detergent granules that contains LAS, and this is that the previously known technology can not obtain.But anionic group also can be PAS, LES or any other anion surfactant, and the mixture of these components and LAS or do not contain the mixture of LAS.
The most common form with free acid of LAS is commercially available.Different with very unsettled PAS acid, LAS acid is very stable and the market sale of many manufacturers arranged, Petralab 550 (Petresa) for example, Deter (Deter), Marliean (Huls), Nalkylene 540L (Vista) and Isorchem L83 (Enichem).As a kind of viscous liquid, it is easy to handle, stores and processing.Under any circumstance, the liquid anion precursor substance of anion surfactant and neutralizing agent are sent into the inlet region of drying zone or drying zone and formed anion surfactant on the spot, just can in drying zone, form mashed prod.
The LAS acid that is neutralized is with Powdered commercially available.
The LAS powder mainly is a roller drying or spray-dired, has reasonable powder property during newborn output.But seldom preferably adopt, because they can absorb moisture and the intractable that becomes sticky from air, their flowability degenerates and becomes and lumps easily.The typical powder that can obtain (available from Huls) from market is Marlan ARL (80%LAS), Marlan A390 (90%LAS), Marlan A396 (96%LAS), or (available from Unger) Ufaryl DL90 (90%LAS), Ufaryl DL85 (85%LAS) and Ufaryl DL80 (80%LAS).
The PAS that buys on market at present is finely powdered or noodles shape.Fine powder generally is a dust-like, contains in a large number the particle less than 150 microns.Generally with the dry PAS of soap flakes shape through the extrusion production strip PAS that appears, it has very big particle size and very low porosity generally speaking, causes solubility property very poor.Be to increase the content of detergent active material in the detergent composition, the detergent particles that feeds intake after the what is called is arranged as everyone knows, can provide activity substance content high composition.
But, after being not suitable in general, finely powdered PAS and noodles shape PAS be dosed in the washing combination, particle size is different in general because composition grain is with the rearmounted particle that drops into, and it is very poor therefore to tend to segregation and outward appearance.The obtainable washing granule of the method according to this invention has high-load detergent active material, suitable porosity and particle size characteristic.
So, a third aspect of the present invention provides the anionic surfactant granules that contains particle weight 60% at least, preferably contain LAS or form by LAS, and containing the detergent particles that is no more than 5% water, this particle is coated with according to the present invention first or the stratification agent that obtains of the method for second aspect by bag.
According to a forth aspect of the invention, the detergent particles that contains anion surfactant is provided, preferably contain LAS or form by LAS, and preferably its amount is at least 60% of particle weight, and wherein, this particle is coated with the stratification agent by bag, and containing porosity is 0% to 25% of particle volume, size-grade distribution is as follows: at least 80% particle size is at 180 to 1500 microns, preferred 250 to 1200 microns, and less than 10% and preferably less than 5% particle diameter less than 180 μ m.
In this detergent particles, the amount of suitable anion surfactant is at least 70% of a particle weight, preferably at least 80%, preferably at least 85%.Preferably this particle also contains water, and its amount is 0% to 8%, preferred 0 to 4% of particle weight.Water in the particle can improve particle integrity, thereby reduces fine grain amount.
Preferably the long-width ratio of detergent particles is no more than 2, more preferably totally is that spheric is emanated out to reduce from other particle of preparation said composition, and improves the profile directly perceived of powder.
Preferred LAS anion surfactant chain length is C
8To C
16, more preferably from C
9To C
15, most preferably from C
10To C
14Close limit.
If add PAS, this tensio-active agent chain length is C
10To C
22, preferred C
12To C
18, more preferably C
12To C
14Close limit, Coco PAS is especially desirable.
Detergent particles can contain PAS and other tensio-active agent and/or nonsurfactant mixture of ingredients on demand.
Other suitable tensio-active agent can comprise the straight chained alkyl ether sulfate, the oxo process alcohol sulfate.C for example
11To C
15And C
13To C
15Alcohol sulfate, secondary alcohol sulfate and sulfonate, unsaturated tensio-active agent is sodium oleate, oleyl sulfate, alkene sulfonate for example, or its mixture.
Especially preferably be rich in the detergent particles of LAS, promptly wherein the amount of LAS more preferably surpasses the total amount of all other tensio-active agents and nonsurfactant above the amount of any other tensio-active agent or nonsurfactant.
To adopt the sodium salt of tensio-active agent in general, but also may have the salt of K, Ca or Mg.Yet the inlet region before preferably the anion surfactant of sour form and neutralizing agent being sent into drying zone or be right after drying zone forms anion surfactant on the spot, to form this anionic group.
If generate anionic agent on the spot in drying zone, the neutralization heat of then emitting in drying zone can reduce the required of indirect heating drying zone, thereby is very beneficial for the method that adopts the tensio-active agent mashed prod to make raw material.
And, if precursor acids can liquid state rather than aqueous solution mode send into drying zone, and neutralizing agent can concentrate, that also is good.The total amount that enters the water of drying zone is compared and can be significantly reduced with the method that adopts the tensio-active agent mashed prod.Described mashed prod may need the water of at least 30% weight can be pumped fortune.
Also can before adding the stratification agent, directly form detergent particles from the precursor acid starting material, rather than two step method: generate tensio-active agent, then form mashed prod and dry, to form detergent particles.Its advantage is to avoid forming the tensio-active agent mashed prod, because it need carry and store this mashed prod, and gives the technical difficulty that causes.
Precursor acids, for example LAS or PAS acid are suitable for sending into drying zone with liquid phase.Because precursor acids may be heat-labile,, make to reduce to minimum, and preferably can avoid fully because caused this acid heat of the temperature that raises decomposes so preferred N-process should be enough fast, and react completely basically.
Precursor acids is suitable for being 40 to 60 ℃ in temperature carries down, is that liquid state is unlikely thermolysis again to guarantee it.Neutralizing agent can be at any temperature required drying zone of input down.
The neutralizing agent of introducing is suitable to the aqueous solution or slurries or solid material introducing.
The conventional neutralizing agent that can adopt comprises alkali-metal oxyhydroxide, for example sodium hydroxide and alkali-metal carbonate, and for example yellow soda ash preferably adds with solid material.
The amount of neutralizing agent is advisable with 25 to 55% of the aqueous solution or slurry weight, and preferred 30 to 50%.Neutralizing agent concentration height may cause undesirable crystallization effect, and concentration is low because the ratio of water is undesirable too greatly also.
For water-content in the control drying zone can change the concentration of neutralizing agent solution or slurries.So just can reach best viscosity characteristics, thus make material in the drying zone keep carrying/can be pumped the state of fortune.
Can adopt neutralizing agent with respect to precursor acids excessive amount on stoichiometric ratio.As the thermolysis of fruit part precursor acids, issuable acid, for example sulfuric acid can combine with excessive neutralizing agent.
Contain in advance the method for the mashed prod of neutral tensio-active agent with employing and compare, adopt neutralization on the spot can export product fast.
Precursor substance in the stirring heating district and neutralizing agent (hereinafter being referred to as raw material) can provide effective heat transfer in general and help removing moisture.Stir the duration of contact that reduces between raw material and the drying zone wall, add net heat and shift, just can reduce the possibility that causes pyrolysated " hot spot " to form.And, drying improve can shorten in the drying zone the residence time/raising output.
Other nonsurfactant component that can exist in the detergent particles comprises dispersion aids, preferred polymers dispersion aids, more preferably urea, sugar, polyalkylene oxide and hereinafter described washing assistant.
If necessary, this detergent particles can contain organic and/or inorganic salt, but as the salt of hydration.Suitable material in the salt, tri-polyphosphate, Citrate trianion, carbonate, vitriol, the muriate of preferred sodium.Also can comprise silico-aluminate, clay, silica and other inorganic materials.
This particle can contain one or more nonionogenic tensides, for example below about being mentioned with the matrix powder of this particle fusion those.
Also can comprise inorganic materials in same this particle, for example PEG and other polymkeric substance washing assistant or soap class, those as hereinafter mentioning.
When the anion surfactant component contains LAS, there is salt in preferred especially this particle.
The amount of salt can be up to 50% of this particle weight, and is preferably the highest by 30%.
This detergent particles is dosed in the resulting matrix powder of conventional washing composition production method after can be directly, ordinary method comprises the non-tower production method, wherein all components of detergent composition are pressed method mixing and the granulating of describing among the EP-A-367 339, and comprise spray-drying process (then can select rearmounted tower multiviscosisty).Because the detergent particles that the present invention produces can be dosed into later in this powder, so formulation flexibility is very big, and the amount of active substance can strengthen on demand in whole compositions formulated.Further advantage is to produce the matrix powder that is substantially free of the washing composition active material, and the washing composition property controlled compound go up substantially can be fully as after the particle that feeds intake add.
Therefore another aspect of the present invention provides the cleaning composition that contains described detergent particles in the present invention third and fourth aspect and matrix powder.
When the matrix powder was produced with spray-drying process, detergent active material content was particularly advantageous in the selection reduction matrix powder, thereby because the low high yield that can guarantee of detergent active compound content improves integral production efficient in spray-drying process.
