Title (DE) VERFAHREN ZUR HERSTELLUNG ANIONISCHER TENSIDE MIT SULFATSTRUKTUR
(EN) PROCESS FOR PRODUCING ANIONIC TENSIDES WITH A SULPHATE STRUCTURE
(FR) PROCEDE DE PRODUCTION D'AGENTS TENSIO-ACTIFS ANIONIQUES A STRUCTURE SULFATEE
Abstract:
(DE) Neue anionische Tenside mit Sulfatstruktur sind dadurch erhältlich, daß man Umsetzungsprodukte von epoxidierten Fettsäureglycerinestern mit einer Verbindung aus der von Wasserstoff, Wasser, aliphatischen Alkoholen und deren Ethylenoxidaddukten sowie aliphatischen Carbonsäuren gebildeten Gruppe nach Anlagerung von Ethylenoxid sulfatiert und die gebildeten Schwefelsäurehalbester mit Basen neutralisiert. Die Produkte zeigen gute oberflächenaktive Eigenschaften und können in flüssigen Wasch- und Reinigungsmitteln eingesetzt werden.
(EN) In a process for producing new anionic tensides with a sulphate structure, reaction products of epoxidized fatty acid glycerin esters with a compound from the group consisting of hydrogen, water, aliphatic alcohols and their ethylene oxide adducts as well as aliphatic carboxylic acids are sulphatized following addition of ethylene oxide, and the sulphuric acid semi-esters formed are neutralized with bases. The products exhibit good surface active properties and can be used in liquid washing and cleaning agents.
(FR) On obtient de nouveaux agents tensio-actifs anioniques à structure sulfatée en sulfatant des produits de réaction d'esters d'acides gras glycériques époxydés avec un composé du groupe formé par l'hydrogène, l'eau, les alcools aliphatiques et leurs produits d'addition avec de l'oxyde d'éthylène, ainsi que les acides carboxyliques aliphatiques, après l'addition de l'oxyde d'éthylène, puis on neutralise avec des bases les semi-esters d'acide sulfurique ainsi obtenus. Ces produits ont de bonnes propriétés tensio-actives et peuvent être utilisés dans des lessives et détergents liquides.
