2148100 9412472 PCTABS00032 Polyhydroxy fatty acid amide nonionic surfactants are converted in high yields to their sulfated analog surfactants using an SO3/pyridine complex as a sulfating agent. Thus, C12-C18N-methyl glucamide is sulfated in methylene chloride or pyridine solvent to form the corresponding sulfated glucamide in yields of 80 % or higher.
