Abstract

The process of producing alkoxylated thiodiglycol sulfoxide derivatives and thiodiglycol sulfone derivatives corresponding to formula I ##STR1## wherein X.sub.1 and X.sub.2 may be the same or different and represent a hydroxyl-substituted aklyl radical containing 8 to 30 carbon atoms, an acyl radical of an alkyl monocarboxylic acid containing 8 to 30 carbon atoms, and X.sub.1 or X.sub.2 may be hydrogen, R represents hydrogen or methyl, z is 1 or 2, n is 0 to 25 and m is 1 to 25, by reacting an alkoxylated thiodiglycol with a C.sub.8 14 C.sub.30 .alpha.-olefin expoide or a C.sub.8 -C.sub.30 monocarboxylic acid in a molar ratio of about 1:1 to about 1:2, and oxidizing the mono- and bis- ethers or mono- and bis- esters formed to the sulfoxide or sulfone derivatives.
