Preparation of alkoxyalkyl glyceryl ether sulphonates and compositions containing them

摘要

A process for preparing alkoxylated alkyl glyceryl ether sulfonates which comprises reacting in the presence of water and the absence of ethanol a mixture of alkoxylated glycidyl ethers having as the major quantity of alkoxylated material with a salt of a sulfite bisulfite salt mixture at a temperature 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 has an average value of 1 to 10 and obtaining a sulfonated alkoxylated product having as a major quantity of the alkoxylated material a salt of R(OCH2CHR')nOCH2CHOHCH2 SO3<->. The above compounds in the form of semi solid mixtures are also claimed.
