Title (DE) VERFAHREN ZUR HERSTELLUNG VON ALKYL-POLYETHOXYETHERSULFATEN
(EN) PROCESS FOR MAKING ALKYL POLYETHOXY ETHER SULPHATES
(FR) PROCEDE DE FABRICATION DE SULFATES D'ALKYL-POLYETHOXYETHERS
Abstract:
(DE) Durch Sulfatierung ethoxylierter Alkanole, die durch Hydrotalcit-katalysierte Reaktion von Ethylenoxid mit Alkoholen mit 8 bis 22 C-Atomen entstehen, lassen sich Alkyl-polyethoxyethersulfate erhalten, die sich durch einen niedrigen Dioxangehalt und besonders gute Verdickbarkeit mittels üblicher Elektrolyte auszeichnen.
(EN) The sulphatisation of ethoxylised alkanols obtained by the reaction of ethylene oxide with alcohols with 8 to 22 C atoms in the presence of a hydrotalcite catalyst provides alkyl polyethoxy ether sulphates distinguished by a low dioxane content and extremely good coagulability using ordinary electrolytes.
(FR) Par sulfatation d'alcanols éthoxylés qui se forment par réaction, catalysée à l'hydrotalcite, d'oxyde d'éthylène avec des alcools de 8 à 22 atomes de carbone, on obtient des sulfates d'alkyl-polyéthoxyéthers qui sont remarquables par leur faible teneur en dioxanne et par leur pouvoir épaississant avec les électrolytes courants particulièrement bon.
