Abstract
The invention is a process for producing alkaline earth metal salicylates for use as lubricant detergents and to compositions prepared by the process. The process comprises two steps. Step 1 is the alkylation of salicylic acid is conducted using C<14> or greater linear alpha-olefins to produce alkyl salicylic acids in commercially acceptable yields. The alkylation conditions produce predominately mono-substituted para alkyl salicylic acids that are oil soluble. Step 2 is the oil soluble acid is subsequently neutralized and overbased by carbonation of lime using CO<2> in the presence of a promoter and a surfactant. The reaction mixture after overbasing is filtered and solvents are removed by distillation. Alternatively, alkyl salicylic acid can be reacted with a previously overbased alkaline earth sulfonate, e.g., calcium sulfonate, to produce alkaline earth salicylate salts comprising varying percentages of dispersed alkaline earth carbonate salts. In this method, no filtration of the end product is required, and, thus, it is commercially preferred.
Description
Technical field
The present invention relates to the method that a kind of preparation is used for the high-alkaline base earth metals sanitising agent of lubricating oil.
Background technology
The additive that the alkaline earth salt of application organic carboxyl acid is made lubricating oil composition is known.These salt have dispersing agent performance, help to guarantee that engine cylinder inside keeps clean, and contain the deposition of carbon products on the elimination piston with in the piston groove, thereby prevent the piston ring bonding.
Alkalescence (or high alkalinity) alkaline earth salt for preparing these acid also is known.High alkalinity provides alkalescence to stock, and when using in lubricating oil composition, the acidic cpd reaction that it forms in operating process with the engine of using described composition also makes it neutralization.Therefore, issuable any sludge is owing to the dispersing agent performance of this salt disperses, and those acid that might strengthen sludge formation are neutralized.
High alkaline salicylate prepares by making corresponding alkylation Whitfield's ointment high alkalinityization.Alkyl is generally the chain alkyl greater than about 14 carbon atoms, thereby makes it have oil soluble.The salicylic preparation of alkylation by making the phenol alkylation to form alkylphenol, makes alkylphenol carboxylated so that the alkylation Whitfield's ointment to be provided by the Kolbe-Schmitt reaction usually then.The unfavorable economical effectiveness that produces except using high temperature and/or high pressure, the Kolbe-Schmitt route generates the alkylation Whitfield's ointment, and there are the following problems: when main application straight chained alkyl raw material, not every long chain alkylphenol can both be by carboxylated.Specifically, mainly utilize the conventional phenol alkylation of straight chained alkyl raw material that about 50: the 50 neighbour-alkylphenol and the mixture of right-alkylphenol are provided.Though Kolbe-Schmitt reaction is easy to carboxylated resulting long-chain right-alkylphenol, but resulting long-chain neighbour-alkylphenol but has lower reactivity, only has an appointment usually in the total amount of the alkylphenol that is obtained by main straight chain hydrocarbonylation raw material in this reaction 70% to be converted into the alkylation Whitfield's ointment.
A method that addresses this problem is to make alkyl salicylate (as wintergreen oil) alkylation, makes the hydrolysis of resulting alkylation alkyl salicylate so that the alkylation Whitfield's ointment to be provided then.The alkylation of alkyl salicylate is at US 5,434, and is open in 293.

Not refining, that refined all can be used in the lubricating oil of the present invention with oil refining.Lian Zhi oil is not for handling directly by those oil natural or that synthetic source obtains without being further purified.For example directly operate the shale oil that obtains, the oil or the direct ester oil that is obtained by esterification process that are directly obtained by distillation by destructive distillation, these oil are used without further processing, are called not refining oil.The oil of refining with do not refine oils seemingly, just their are further handled in one or more purification steps, to improve one or more characteristics.Multiple this class purification technique such as distillation, solvent extraction, acid or alkali extract, filter and soak into, and all are known concerning those skilled in the art.Refining oil by with obtain refining the similar method of oily institute's application method and obtain, but its application to as if already used oil.This refining oil is also referred to as recovered oil or handling oil again, and often carries out additional processing to remove useless additive and oil decomposition product by technology.
Especially, the present invention relates to engine oil formulation and additive thereof.As using here, term " engine oil " refers to the lubricating oil that can use in engine oil, and for example it comprises automotive oil or diesel engine oil.Lubricating oil composition of the present invention also is suitable for the lubricated ship engine that includes four-stroke trunk-piston engine and two stroke crosshead engines.
Making up oil have the interior viscosity of lubricant viscosity scope, is generally about 45-6000SUS under 100 (about 38 ℃).Lubricating oil also can contain one or more high-alkaline base earth metals sanitising agents, its at least a metallic neutrality and high alkaline salicylate that is as described herein based on alkyl salicylate.Detergent components accounts for significant quantity generally, and its scope is generally 0.01-25wt%, is preferably 0.1-10wt%, more preferably 0.1-5.0wt%.If not indicated otherwise, all weight percent is all in the weight of whole lubricating oil composition.
The amount of the multifunctional additive for lubricating oils that is comprised in final lubricating oil will depend on the character of final application.Concerning marine lubricant, making TBN usually is that 9-100 is just enough; Concerning automobile engine lubricating oil, making TBN is that 4-20 is just enough.
As using here, term " total basicnumber " or " TBN " refer in 1 gram additive, the equivalent amount of alkali with respect to milligram KOH.Therefore, the TBN number is high more, reflects that it is the stronger product of alkalescence, and therefore has higher alkalescence and stock.The total basicnumber of compositions of additives can be determined at an easy rate by ASTM methods of test D2896 or other equivalent processes.
Final lubricating oil also can contain the traditional lubrication oil additive of one or more other types of significant quantity, for example viscosity index improver, anti-wear agent, antioxidant, dispersion agent, rust-preventive agent, pour point depressor, and analogue.
To become more obvious by following embodiment advantage of the present invention and key character.

3The final salicylate of vaterite form.
Condition is identical with embodiment 2, just except adding 20 gram methyl alcohol, also will add 20 gram water.Strengthen polarity and make tensio-active agent colloid instability, and make amorphous oil soluble CaCO
3Be converted into crystal vaterite.The finished product are very sticking, and are very muddy, are unsuitable for using.
Under the situation that does not depart from ultimate principle of the present invention, can carry out many changes and improvements, therefore should understand protection scope of the present invention with reference to appended claim.
Claims (3)
