Production and properties of fatty acid polyglycol ester sulfates



Production and properties of fatty acid polyglycol ester sulfates



Fette Seifen Anstrichmittel 88(1): 20-25



Fatty alcohol oxethylates, produced by reaction of fatty alcohols from hydrogenated fatty acid methyl esters with ethylene oxide, are the basic material for an important class of anionic tensides, the fatty alcohol ether sulfates. The fatty acid polyglycol ester sulfates. The fatty acid polyglycol ester sulfate are a very interesting alternative to the fatty alcohol ether sulfates. The former are available by saving hydrogenation, in principle directly by fatty acid oxethylation or interesterification of fatty acids with polyglycols, followed by sulfatation. We report about the production of fatty acid ester sulfates by sulfatation of the fatty acid polyglycol monoesters by sulfurtrioxide or chlorosulfonic acid. By means of the results of physicochemical measurements and process trials it is discussed how far fatty acid polyglycol monoester sulfates are suited as alternative tenside raw material fatty alcohol ether sulfates.
