摘要

A continuous process for preparing alkoxylated alkyl glyceryl ether sulfonates which comprises reacting in the presence of water a mixture of an alkali metal sulfite and bisulfite with a mixture of alkoxylated glycidyl ethers comprising a major quantity of a 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 at an elevated temperatures of at least 125C, a pressure sufficient to maintain the reaction mass liquid at the reaction temperature and at least 20 wt% of the reaction mass is sulfonated product. The latter is achieved by recycling a part of the reaction product to the feet of the sulfonation reactor.
