Abstract

The catalytic activity of colloidal silica sulfonic acid for the hydrolyses of diazinon [diethyl 2- isopropyl-6-methyl-4-pyrimidinyl phosphorothioote] and triphenylmethyl fluoride was compared with that of silica gel sulfonic acids, gel and macroporous poly (styrenesu1fonic acids), powdered and soluble Nafion, p-toluenesulfonic acid, and hydrochloric acid. For diazinon hydrolysis, the colloidal catalyst was only slightly less active than the soluble ...
