Process and composition

摘要

A process for preparing an alkoxylated alkyl glyceryl ether sulfonate which comprises reacting a terminal glycidate (epoxy) of the structure <IMAGE> with a sulfite salt, a bisulfite salt or a sulfite/bisulfite salt mixture at a temperature at or below about 110 DEG C. wherein R is an alkyl or alkenyl of 10 to 20 carbon atoms, inclusive, R' is hydrogen or methyl and n is an integer having an average value of 1 to 10 and obtaining the sulfonate of the structure R(OCH2CHR1)nOCH2CHOHCH2SO3-
