ABSTRACT:
p-Acyloxybenzene sulfonates, well suited for detergency applications, are facilely and rapidly prepared by acylating an alkali or alkaline earth metal, or ammonium p-phenol sulfonate, with an anhydride of a straight or branched chain carboxylic acid having from 7 to 12 carbon atoms, in a polar aprotic solvent and in the presence of a catalytically effective amount of an organic sulfonic acid.
