Abstract:
A composition comprising a mixture of sulfonate compounds of formulas (I), (I-A), and (I-B) ##STR20## wherein i is an integer from 0 to 10; M is selected from the group consisting of lithium, sodium, potassium and ammonium cations and mixtures thereof;R.sup.1 is (ALK--O).sub.p H or H, wherein p is an integer from 1 to 10, each ALK is independently ethyl or propyl; and R is straight or branched alkyl or alkenyl containing 8 to 18 carbon atoms and 0 to 3 carbon-carbon double bonds,wherein the mixture contains compounds of formula (I) wherein d is 1, 2, 3 and 4 and optionally 5, wherein the mole average value of d in the mixture is 1.8 to 2.2;the composition produced by a process comprising:(a) forming a mixture of glyceryl halides of formulas (II), (II-A), and (II-B) ##STR21## by reacting epichlorohydrin with an alcohol or alcohol ethoxylate of the formula R--O--(CH.sub.2 CH.sub.2 O)--H to form the mixture of glyceryl halides of formulas (II), (II-A), and (II-B), and optionally alkoxylating the pendant hydroxyl group on the compounds of formula (II); and then(b) replacing the chloro substituents on the compounds of formulas (II), (II-A), and (II-B) with --SO.sub.3 M, thereby forming the mixture of sulfonate compounds.
