Vaske- og rensemiddel. Detergent and cleaning agent.
Det er kjent til vaske- og rensemidler som inneholder'overflateaktive forbindelser å sette stoffer som forbedrer vaske- It is known to detergents and cleaning agents that contain surface-active compounds to add substances that improve washing

Det dreier seg da for det meste om poly-anioniske polymere som enten fremstilles av naturstoffer som cellu- Substances designated as carriers prevent resorption of the loosened dirt on the cleaned surfaces. It is then mostly about poly-anionic polymers that are either produced from natural substances such as cellulose
lose, gelatin eller lim eller ved polymerisasjon av vinylforbindelser som akrylsyre, metakrylsyre, maleinsyre og deres blandinger med kopoly-meriserbare olefiner. Også polysulfonatene av vinylpolymere ble allerede anbefalt som grågjøringsinhiberende tilsetninger-til vaske- loose, gelatin or glue or by polymerization of vinyl compounds such as acrylic acid, methacrylic acid, maleic acid and their mixtures with copolymerizable olefins. Also the polysulfonates of vinyl polymers were already recommended as greying-inhibiting additives - for washing -
og rensemidler. Av de angjeldende forbindelser har imidlertid bare and cleaning agents. Of the compounds in question, however, only
karboksymetylcellulosen fått en større teknisk betydning, da den i sin grågjøringsinhiberende virkning overtreffer.alle tidligere kjente syntetiske polymere. Karboksymetylcellulosen og også de nevnte syntetiske polymere har imidlertid den ulempe at deres grå-gjøringsnedsettende virkning er begrenset til oellulosefibre, mens de ved vasking av syntetisk fibermateriale spesielt slike av polyamider, polyestere og polyolefiner, praktisk talt er uvirksomme. Denne ulempe gjør seg spesielt bemerkbar overfor hvite tekstiler av syntesefibre resp. blandingsvevnader av syntese- og cellulosefibre, som ved bruk på tross av stadig vasking grågjøres irreversibelt og således får et dårlig utseende. carboxymethyl cellulose has gained greater technical importance, as it surpasses all previously known synthetic polymers in its greying-inhibiting effect. However, the carboxymethyl cellulose and also the aforementioned synthetic polymers have the disadvantage that their greying-reducing effect is limited to non-cellulose fibres, while they are practically ineffective when washing synthetic fiber material, especially polyamides, polyesters and polyolefins. This disadvantage is particularly noticeable with white textiles made of synthetic fibers or mixed fabrics of synthetic and cellulose fibres, which become irreversibly gray when used despite constant washing and thus acquire a poor appearance.
Det besto den oppgave å tilveiebringe et middel som ikke har de ovennevnte ulemper. The task was to provide a means which does not have the above-mentioned disadvantages.
Oppfinnelsen vedrører vaske- og rensemiddel som erkarakterisert vedat det som gråhetshindrende middel inneholder fra 0,1 til 20 vektprosent, referert til midlets samlede vekt, av vannoppløselige salter av karboksylgruppeholdige polyamider, fremstilt ved polymerisering av trikarboksylsyre og/eller tetrakarboksyl-syre og diaminer inneholdende 2 til 18 karbonatomer, hvori eventuelt inntil 50 molprosent av tri- eller tetrakarboksylsyren er erstattet med dikarboksylsyrer. The invention relates to a detergent and cleaning agent which is characterized in that it contains from 0.1 to 20% by weight, referred to the agent's total weight, of water-soluble salts of carboxyl group-containing polyamides, produced by the polymerization of tricarboxylic acid and/or tetracarboxylic acid and diamines containing 2 to 18 carbon atoms, in which possibly up to 50 mole percent of the tri- or tetracarboxylic acid has been replaced by dicarboxylic acids.
Por de karboksylgruppeholdige polyamider lar det seg angi følgende generelle formel: For the carboxyl group-containing polyamides, the following general formula can be stated:
idet A betyr hydrokarbonresten av diaminet, where A means the hydrocarbon residue of the diamine,
B betyr hydrokarbonresten av tri- eller tetrakarboksylsyren, m = 1 eller 2,. og B means the hydrocarbon residue of the tri- or tetracarboxylic acid, m = 1 or 2,. and
n = 4 til 1000. n = 4 to 1000.
Symbolet n betyr polyamidets polymerisasjonsgrad. Slik nyere undersøkelser har vist ligger denne polymerisasjonsgrad mellom 4 og 1000. The symbol n means the degree of polymerization of the polyamide. As recent research has shown, this degree of polymerization is between 4 and 1000.
Inntil 50 molprosent av tri- eller tetrakarboksylsyrene kan være erstattet med dikarboksylsyrer med formel hvor B' betyr hydrokarbonrest, og A og B har ovenfor nevnte betydning, samt X i formel I og II betyr hydrogen eller alkalimetall eller ammoniumion, x + y = 1, x = 0,5 til 1, y = 0 til 0,5. Up to 50 mole percent of the tri- or tetracarboxylic acids can be replaced by dicarboxylic acids with the formula where B' means a hydrocarbon residue, and A and B have the meaning mentioned above, and X in formulas I and II means hydrogen or alkali metal or ammonium ion, x + y = 1, x = 0.5 to 1, y = 0 to 0.5.
De i de nye vaskemidler i saltform inneholdte polyamider fremstilles etter kjente fremgangsmåter. Som utgangsstoffer kommer det på tale alifatiske, cykloalifatiske og aromatiske tri-resp. tetrakarboksylsyrer, spesielt sitronsyre, trikarballylsyre, nitrilotrieddiksyre, etylendiamino-tetraeddiksyre, cykloheksantri-karbonsyre, trimesinsyre, oksytrimesinsyre og pyromeliitsyre. De nevnte syrer kan inntil 50 molprosent erstattes med alifatiske eller cykloalifatiske, mettede eller umettede såvel som aromatiske dikarboksylsyrer, som malon-, ravsyre-, glutar-, adipin-, sebacin-, malein- og fumarsyre såvel som benzoldikarboksylsyrer. De flerverdige karboksylsyrer som skal anvendes inneholder generelt inntil 20 karbonatomer. The polyamides contained in the new detergents in salt form are produced according to known methods. Aliphatic, cycloaliphatic and aromatic tri-resp. tetracarboxylic acids, especially citric acid, tricarballylic acid, nitrilotriacetic acid, ethylenediaminotetraacetic acid, cyclohexantricarboxylic acid, trimesic acid, oxytrimesic acid and pyromellitic acid. The mentioned acids can be replaced by up to 50 mole percent with aliphatic or cycloaliphatic, saturated or unsaturated as well as aromatic dicarboxylic acids, such as malonic, succinic, glutaric, adipic, sebacic, maleic and fumaric acids as well as benzenedicarboxylic acids. The polyvalent carboxylic acids to be used generally contain up to 20 carbon atoms.
De angjeldende, fortrinnsvis 2 til 12 karbonatomholdige diaminer kan være rettlinjede eller forgrenede, mettede eller umettede, cykloalifatiske såvel som aromatiske og avbrutt med heteroatomer som 0, N og S. Eksempler for slike diaminer er etylen-diamin, propylendiamin, tetrametylendiamin, pentametylendiamin, The diamines in question, preferably containing 2 to 12 carbon atoms, can be linear or branched, saturated or unsaturated, cycloaliphatic as well as aromatic and interrupted by heteroatoms such as 0, N and S. Examples of such diamines are ethylenediamine, propylenediamine, tetramethylenediamine, pentamethylenediamine,
heksametylendiamin, p-fenylendiamin, benzidin, piperazin, 4,4'-diaminodifenylsulfon og 4,4'-diaminodifenyleter. hexamethylenediamine, p-phenylenediamine, benzidine, piperazine, 4,4'-diaminodiphenylsulfone and 4,4'-diaminodiphenyl ether.
Polyamidenes fremstilling foregår på kjent måte, eksempelvis ved flere timers oppvarmning av den av syre og diamin bestående blanding i vakuum eller i nærvær av et oppløsningsmiddel, hvormed reaksjonsvannet kan avdestilleres azeotropt. Istedenfor de frie di-, tri- eller tetrakarboksylsyrer kan det også anvendes deres reaksjonsdyktige derivater, f.eks. anhydridene som utgangsstoffer. The polyamides are produced in a known manner, for example by heating the mixture consisting of acid and diamine for several hours in a vacuum or in the presence of a solvent, with which the reaction water can be azeotropically distilled off. Instead of the free di-, tri- or tetracarboxylic acids, their reactive derivatives can also be used, e.g. the anhydrides as starting materials.
Ved valg av molforhold mellom polykarboksylsyre og diamin innen et foretrukket område fra 1,1 : 0,9 til 0,9 : 1,-1 lar polymerisasjonsgraden seg variere innen visse grenser. I interesse for en god grådannelseshindrende virkning er imidlertid å tilstrebe en høy polymerisasjonsgrad. For unngåelse av en for tidlig kjede-nedbrytning foretrekkes derfor et molforhold som ligger nærmest mulig ved 1:1. By choosing the molar ratio between polycarboxylic acid and diamine within a preferred range from 1.1:0.9 to 0.9:1.-1, the degree of polymerization can be varied within certain limits. However, in the interest of a good greying-preventing effect, a high degree of polymerization should be striven for. To avoid premature chain breakdown, a mole ratio that is as close as possible to 1:1 is therefore preferred.
De på angitt måte fremstilte frie karboksylgruppeholdige polyamider er av harpikslignende konsistens, uoppløselig i vann og i organiske oppløsningsmidler, derimot lett oppløselige i fortynnede alkaliluter. De kan dessuten inneholde underordnede mengder av lavmolekylære amider resp. av ikke omsatte utgangsstoffer, som kan fjernes ved ekstrahering med organiske oppløsningsmidler og eventuelt på nytt bringes til omsetning. Da disse forbindelser imidlertid ikke influerer på midlenes rensningsegenskaper, er en ad-skilling generelt ikke nødvendig. The free carboxyl-group-containing polyamides produced in the manner indicated are of a resin-like consistency, insoluble in water and in organic solvents, on the other hand, easily soluble in dilute alkali solutions. They may also contain minor amounts of low molecular weight amides or of unreacted starting materials, which can be removed by extraction with organic solvents and possibly brought back into circulation. However, as these compounds do not influence the cleaning properties of the agents, an ad separation is generally not necessary.
På grunn av de høymolekylære forbindelsers uoppløselig-het i organiske oppløsningsmidler og på grunn av deres innhold av lavmolekylære mengder svikter de vanlige metoder for en molekylvekt-bestemmelse. Polyamidenes polymerisasjonsgrad og molekylvekt lar seg derfor ikke angi med tilstrekkelig nøyaktighet. Due to the insolubility of the high-molecular compounds in organic solvents and due to their content of low-molecular quantities, the usual methods for a molecular weight determination fail. The degree of polymerization and molecular weight of the polyamides cannot therefore be specified with sufficient accuracy.
Vaskemidlene kan inneholde ønskelige vannoppløselige salter av polyamidene ifølge oppfinnelsen, fortrinnsvis alkalimetall-dg ammoniumsaltene. Med-ammoniumsalter er det også å forstå saltene av uorganiske ammoniumbaser. Polyamidene kan settes til vaskemidlene også i form av de frie syrer, hvis alkalisk reagerende stoffer er. til stede i et for saltdannelsen tilstrekkelig overskudd. The detergents may contain desirable water-soluble salts of the polyamides according to the invention, preferably the alkali metal ammonium salts. With-ammonium salts is also to be understood as the salts of inorganic ammonium bases. The polyamides can also be added to the detergents in the form of the free acids, if alkaline reacting substances are. present in an excess sufficient for salt formation.
Foruten polyamidénes salter inneholder de hye vaske-og rensemidler de i slike midler vanlige overflateaktive stoffer, eksempelvis slike av sulfat- eller sul-fonattypen som primære og sekundære alkylsulfater såvel som sulfatene av etoksylerte eller propoksylerte fettalkoholer, videre alkylbenzolsulfonater, primære og sekundære olefinsulfonater, alkylsulfonater og ct-sulfofettsyre-estere. Ytterligere forbindelser av denne klasse, som eventuelt kan finne anvendelse, er de høyeremolekylære sulfaterte partialetere og partialestere av flerverdige alkoholer, sulfatene av etoksylerte eller propoksylerte fettsyreamider og alkylfenoler, videre, fettsyre-taurider og fettsyreisétionater såvel som deres homologer. Egnet er videre alkalisåpene av fettsyrer såvel som fettsyrekondensasjons-produktene av aminosyrer eller nedbyggede eggehvitestoffer. Videre kommer det på, tale amfolyter, som alkylbetainer og alkylsulfobetainer. Midlene kan videre inneholde ikkeioniske vaskeaktivstoffer, som alkyl- og acylpolyglykoleter, alkylfenolpolyglykoleter, blandings-kondensater av polyetylenglykol og polypropylenglykol, fettsyre-sukkerestere, aminoksyder og fettsyrealkanolamider. De nevnte forbindelser kan også anvendes i blanding. Hvis forbindelsene har en alifatisk hydrokarbonrest, skal denne fortrinnsvis være rettlinjet og ha 8 til 22 karbonatomer. I forbindelsene iiied aralifatiske hydrokarbonrester inneholder de fortrinnsvis uforgrenede alkyl- In addition to the salts of the polyamides, the high detergents and cleaning agents contain the surfactants common in such agents, for example those of the sulfate or sulfonate type such as primary and secondary alkyl sulfates as well as the sulfates of ethoxylated or propoxylated fatty alcohols, further alkylbenzene sulfonates, primary and secondary olefin sulfonates, alkyl sulfonates and ct-sulfofatty acid esters. Further compounds of this class, which may possibly find application, are the higher molecular weight sulfated partial ethers and partial esters of polyhydric alcohols, the sulfates of ethoxylated or propoxylated fatty acid amides and alkylphenols, furthermore, fatty acid taurides and fatty acid isethionates as well as their homologues. Also suitable are the alkaline soaps of fatty acids as well as the fatty acid condensation products of amino acids or degraded egg whites. Furthermore, there are ampholytes, such as alkylbetaines and alkylsulfobetaines. The agents can also contain non-ionic detergent active substances, such as alkyl and acyl polyglycol ethers, alkylphenol polyglycol ethers, mixed condensates of polyethylene glycol and polypropylene glycol, fatty acid sugar residues, amine oxides and fatty acid alkanolamides. The aforementioned compounds can also be used in mixture. If the compounds have an aliphatic hydrocarbon residue, this should preferably be straight and have 8 to 22 carbon atoms. In the compounds iiied araliphatic hydrocarbon residues, they preferably contain unbranched alkyl-
kjeder gjennomsnittlig 6 til 16 karbonatomer.chains average 6 to 16 carbon atoms.
De nye vaske- og rensemidler kan dessuten tilsvarende deres eventuelle anvendelsesformål inneholde ytterligere vanlige bestanddeler som pyrofosfater, polyfosfater og høyere kondenserte fosfater såvel som silikater i form av deres alkalisalter, videre oksygenavgivende resp. aktiv-klorhoIdige blekemidler, som alkali-perborat, alkaliperkarbonater, alkalihypokloriter, klorerte cyanur-syrer og deres alkalisalter såvel som nøytralsalter, som magnesium-silikat og nafcriumsulfat. Likeledes kan det være til stede sequestreringsmidler, spesielt alkalisalter av aminopolykarbonsyrer, f.eks. natriumsaltene av aminotrieddiksyre eller etylendiaminotetra-eddiksyre såvel som alkalisaltene av hydroksyalkyl-difosfonsyrer og aminopolyfosfonsyrer, f.eks. dinatriumsaltet av 1-hydroksyetan-1,1-difosfonsyre resp. heksanatriumsaltet av aminotri-(metylen-fosfonsyre). The new detergents and cleaners can also, corresponding to their potential application, contain additional common ingredients such as pyrophosphates, polyphosphates and higher condensed phosphates as well as silicates in the form of their alkali salts, further oxygen-releasing or active chlorine bleaching agents, such as alkali perborate, alkali percarbonates, alkali hypochlorites, chlorinated cyanuric acids and their alkali salts as well as neutral salts, such as magnesium silicate and sodium sulfate. Likewise, sequestering agents may be present, especially alkali salts of aminopolycarboxylic acids, e.g. the sodium salts of aminotriacetic acid or ethylenediaminotetraacetic acid as well as the alkali salts of hydroxyalkyldiphosphonic acids and aminopolyphosphonic acids, e.g. the disodium salt of 1-hydroxyethane-1,1-diphosphonic acid resp. the hexasodium salt of aminotri-(methylene-phosphonic acid).
Som blandingsbestanddeler kommer det også på taleIt is also mentioned as a mixture component
stoffer til regulering av pH-verdien, som natriumkarbonat, natrium-bikarbonat, melkesyre og sitronsyre. substances for regulating the pH value, such as sodium carbonate, sodium bicarbonate, lactic acid and citric acid.
Midlene kan videre inneholde optiske lysgjørere/som derivater av diaminostilbendisulfonsyre eller av diarylpyrazolin-sulfonsyre. Til regulering av skumforholdet kan midlene videre inneholde skumforbedrere, som fettsyreamider eller skumhindrings-midler, spesielt trialkylmelaminer. The agents may also contain optical brighteners/as derivatives of diaminostilbenisulphonic acid or of diarylpyrazoline sulphonic acid. To regulate the foam ratio, the agents can further contain foam improvers, such as fatty acid amides or anti-foam agents, especially trialkyl melamines.
De nye vaske- og rensemidler kan foreligge i fast, spesielt pulverform eller i form av oppløsninger eller pastaer. På -grunn avpolyamddsaltenes gode vannoppløselignet er de spesielt egnet til fremstilling av' flytende vaskemiddelkonsentrater. Slike væske-preparater kan ved siden av de ovennevnte bestanddeler også inneholde hydrotrope stoffer, som lavmolekylære alkylbenzolsulfonater, urin-stoffer såvel som organiske oppløsningsmidler. The new washing and cleaning agents can be available in solid, especially powder form or in the form of solutions or pastes. Due to the good water solubility of the polyamide salts, they are particularly suitable for the production of liquid detergent concentrates. Such liquid preparations can, in addition to the above-mentioned ingredients, also contain hydrotropic substances, such as low molecular weight alkylbenzene sulphonates, urine substances as well as organic solvents.
I noen "tilfeller, eksempelvis ved vasking av tekstil-materialer av "cellulose eller regenerert cellulose, kan vaskevirk-ningen dessuten økes ved tilsetning av vanlige grådannelsesinhibi-torer, spesielt "karboksymetylcelluloBe. De mengder som skal anvendes av karboksymetylcellulose utgjør oa. 0,1 tii 3i>referert til midlets samlede vekt. In some cases, for example when washing textile materials made of cellulose or regenerated cellulose, the washing effect can also be increased by adding common graying inhibitors, especially carboxymethyl cellulose. The amounts to be used of carboxymethyl cellulose amount to, among other things, 0.1 tii 3i>referred to the total weight of the agent.

Av denne stamoppløsning ble hver gang 100 ml fortynnet med springvann av 10° dH til en liter. Prøvene ble vasket ved 60°C 10 min. ved 100 omdreininger pr. minutt av "Terg-0-tometeret", deretter spylt bre ganger med destillert vann, tørket og vurdert fotometrisk. Each time 100 ml of this stock solution was diluted with tap water of 10° dH to one litre. The samples were washed at 60°C for 10 min. at 100 revolutions per minute by the "Terg-0-tometer", then rinsed several times with distilled water, dried and evaluated photometrically.
Eksempel 1.Example 1.
192 g (1 mol) vannfri sitronsyre, 108 g (1 mol) heksametylendiamin og 500 ml xylol ble oppvarmet i en destillasjons-apparatur, som var utstyrt med en innretning til utskilling av vannet og tilbakeføring av oppløsningsmiddel så lenge inntil det ikke mer utskilte seg noe reaksjonsvann i forlaget. Xylolen ble heilt av dannet uoppløselig harpiks og residuet tørket i vakuum. Polyamidet oppløste seg under omrøring i 2-n NaOH. Overskytende lut (ca. 5%) ble nøytralisert med fortynnet svovelsyre og den nøytrale oppløsning innstillet til et polyamidinnhold på 10 g/l. Av denne oppløsning ble det til vaskelutene satt tilsvarende mengder. 192 g (1 mol) of anhydrous citric acid, 108 g (1 mol) of hexamethylenediamine and 500 ml of xylol were heated in a distillation apparatus, which was equipped with a device for separating the water and returning the solvent until no more separated some reaction water in the publisher. The xylene was recovered from the insoluble resin formed and the residue dried in vacuo. The polyamide dissolved under stirring in 2-n NaOH. Excess lye (approx. 5%) was neutralized with dilute sulfuric acid and the neutral solution adjusted to a polyamide content of 10 g/l. Corresponding amounts of this solution were added to the washing solutions.
På tilsvarende måte ble det omsatt:In a similar way, the following was traded:
Vaskeforsøkenes resultater er sammenstilt i følgende tabeller. Grådannelsen av polyestervevnaden ble foretatt etter metode A (Redeposition-metode) etter hver gang fem vaskeprosesser. Vaskeforsøkene med polyamidvevnader ble foretatt etter metode B (Deposition-metode). Forkortelsen CMC betyr karboksymetylcellulose (Na-salt), som ble anvendt til sammenligning. The results of the washing tests are compiled in the following tables. The graying of the polyester fabric was carried out according to method A (Redeposition method) after five washing processes each time. The washing tests with polyamide fabrics were carried out according to method B (Deposition method). The abbreviation CMC stands for carboxymethyl cellulose (Na salt), which was used for comparison.
Resultatene viser en tydelig overlegenhet av midlene ifølge oppfinnelsen i forhold til karboksymetylcellulose. The results show a clear superiority of the agents according to the invention in relation to carboxymethyl cellulose.
