Alkyl ether sulfate surfactants and associated methods of manufacture

Abstract

A process includes the steps of contacting an olefin, an alcohol and a metallosilicate catalyst to form oligomers of an alcohol ethoxylate having structure (I), wherein R1 is an alkyl, R2 is an alkyl, and n has a value of 1 to 3; and sulfating the oligomers of Structure (I) to form oligomers of Structure (II), wherein R1 is an alkyl, R2 is selected from the group consisting of an alkyl group, M is selected from the group consisting of a proton, an ammonium cation, a metal cation, a nitrogen cation, a boron cation, a phosphorus cation, triethylamine, triethanolamine, monoethanolamine and combinations thereof, and n has a value of 1 to 3, and wherein 95 mol % or greater of the oligomers of Structure (II) have an n of 1 and 5 mol % or less of the oligomers of Structure (II) have an n of 2 or greater.
