Abstract:
1. A method of making a compound according to formula (I), wherein each R is independently selected from the group consisting of C4-C20 branched, linear, and cyclic alkyl, alkenyl, aryl, and aralkyl moieties; C4-C20 branched, linear, and cyclic alkyl, alkenyl, aryl, and aralkyl moieties bearing a carbonyl group or one or more heteroatoms selected from O, S, and N; glycol ether moieties of the formula R 3 (OCH 2 CH 2 ) n —; aminoethylene moieties of the formula R 3 (NHCH 2 CH 2 ) n —; and thioether moieties of the formula R 3 S(CH 2 ) n —; wherein R 3 is H or linear C1-C12 alkyl and n is an integer from 1 to 15; and Z is S, SO, or SO 2 ; the method comprising charging to a reactor a sulfide source and an alkoxychlorohydrin according to formula (II) wherein the step of charging the sulfide source and the alkoxychlorohydrin comprises charging water, a base, and gaseous hydrogen sulfide.
