Cosulfation of fatty acid alkanolamides and lower molecular weight alcohols

Abstract and Summary The process for the sulfation of tallow isopropanolamide or of a 50:50 mixture of tallow diglycolamide and isopropanolamide with chlorosulfonic acid was studied. The major obstacle to complete and uniform sulfation was the high viscosity of the sulfation mix. This could be overcome most advantageously by cosulfation with lower molecular weight alcohols, preferably isopropanol. The most fluid reaction mix and product were prepared from the mixed amides. No chlorinated solvent is required for such cosulfations.
