ABSTRACT:
A continuous process for preparing alkoxylated alkyl glyceryl ether sulfonates which comprises reacting in the presence of water a mixture of an alkali metal sulfide and bisulfite with a mixture of alkoxylated glycidyl ethers comprising a major quantity of a ##STR1## wherein R is alkyl or alkenyl of about eight to twenty carbon atoms, R' is H or methyl, n is an average integer value of 1 to about 12 to obtain alkoxylated sulfonated product having as a major quantity of the alkoxylated product ##STR2## at an elevated temperatures of at least 125.degree. C., a pressure sufficient to maintain the reaction mass liquid at the reaction temperature and at least 20 wt % of the reaction mass as sulfonated product.
