Description

Verfahren zur Herstellung von Äthersäuren Es wurde gefunden, daß man die bekannten Alkaliverbindungen des Triäthanolamins und die auf gleiche Weise erhältlichen Alkaliverbindungen seiner Homologen, wie z. B. des Diäthanolpropanolamins oder des Diäthanolbutanolamins, durch Umsetzung mit der äquivalenten Menge oder einem Mehrfachen davon an Monohalogenessigsäure oder Monohalogenpropionsäure bzw. den Alkalisalzen dieser Säuren in Äthersäuren der allgemeinen Formel oder deren Homologen überführen kann. In der Formel ist n = r, 2 oder 3, in =:2, i oder o und die Summe m + n = 3. Die Säuren entstehen zunächst in Form ihrer Alkalisalze und können durch Ansäuern und Abtrennen des entstandenen Alkalihalogenides als solche gewonnen werden. Sie zeichnen sich durch die Fähigkeit aus, Kalkseifen in Wasser in feine Dispersion zu bringen und dadurch unschädlich zu machen, und sind daher besonders als Zusätze zu Wasch-, Netz-, Dispergier- und Durchdringungsmitteln, die in hartem Wasser oder in Chlorkalkbleichbädern verwendet werden sollen, geeignet.Process for the preparation of etheric acids It has been found that the known alkali compounds of triethanolamine and the alkali compounds of its homologues obtainable in the same way, such as, for. B. of diethanolpropanolamine or diethanolbutanolamine, by reaction with the equivalent amount or a multiple thereof of monohaloacetic acid or monohalopropionic acid or the alkali salts of these acids in ether acids of the general formula or can convert their homologues. In the formula n = r, 2 or 3, in =: 2, i or o and the sum m + n = 3. The acids are initially formed in the form of their alkali salts and can be obtained as such by acidifying and separating off the alkali halide formed . They are characterized by the ability to bring lime soaps into fine dispersion in water and thereby render them harmless, and are therefore particularly suitable as additives to detergents, wetting agents, dispersants and penetrants that are to be used in hard water or in chlorinated lime bleach baths , suitable.

Die Umsetzung zwischen den Alkoholaten der Alkylolamine und den halogenessigsauren oder halogenpropionsauren Salzen kann zweckmäßig in einem organischen Lösungsmittel, wie Alkohol, Benzol, Toluol, Äther oder Tetrachlorkohlenstoff, unter Erwärmen am Rückflußkühler oder im Autoklaven vorgenommen werden. Die anorganischen Salze scheiden sich hierbei ab. Aus dem Filtrat können die Salze der Äthersäuren gegebenenfalls nach Einengen gewonnen werden. Beispiel Triäthanolamin wird mit 5o°loiger wäßriger Kalilauge versetzt, wodurch sich die Kaliumverbindung des Triäthanolamins abscheidet, die durch Abschleudern und Trocknen im Vakuum als Trockenprodukt erhaltenwird. 26 Gewichtsteile der Kaliumverbindung des Triäthanolamins und 4o Gewichtsteile monochloressigsaures Kalium werden, in zoo Gewichtsteilen Alkohol suspendiert und mehrere Stunden unter Rückfluß gekocht. Das ausgeschiedene Kaliuinchlorid wird abfiltriext und hierauf das Filtrat eingeengt, bis sich das Alkalisalz der entstandenen Äthersäure ausscheidet. Das Produkt ist für technische Zwecke genügend rein. Nötigenfalls kann es durch Umkristallisieren in bekannter Weise noch weitergereinigt werden.The reaction between the alcoholates of the alkylolamines and the haloacetic or halopropionic salts can expediently be carried out in an organic solvent, such as alcohol, benzene, toluene, ether or carbon tetrachloride, with warming in a reflux condenser or in an autoclave. The inorganic salts separate out here. The salts of the ether acids can optionally be obtained from the filtrate after concentration. Example Triethanolamine is mixed with 50 ° aqueous potassium hydroxide solution, whereby the potassium compound of triethanolamine separates, which is obtained as a dry product by centrifuging and drying in vacuo. 26 parts by weight of the potassium compound of triethanolamine and 40 parts by weight of potassium monochloroacetate are suspended in zoo parts by weight of alcohol and refluxed for several hours. The precipitated potassium chloride is filtered off and the filtrate is then concentrated until the alkali salt of the ether acid formed separates out. The product is sufficiently pure for technical purposes. If necessary, it can be further purified in a known manner by recrystallization.

Die gemäß der Erfindung erhaltenen Äthersäuren können beispielsweise als Zusatz zu Seifen und seifenähnlichen Stoffen aller Art sowie auch zu kalkempfindlichen Farbstoffen zwecks Erhöhung der Beständigkeit gegen hartes Wasser und sonstige kalk- oder magne-`siumsalzhaltige Lösungen verwedet werden.The ether acids obtained according to the invention can, for example as an additive to soaps and soap-like substances of all kinds as well as to lime-sensitive substances Dyes to increase the resistance to hard water and other lime or solutions containing magnesium salts can be used.
