Abstract
The alkaline hydrolysis of O-ethyl O-(p-nitrophenyl) chloromethylphosphonat e catalyzed by the micelles of cetylpyridinium bromide is inhibited on addi tion of KCl, KBr, or sodium salicylate (NaSal). This is caused by both a de crease in the nucleophile concentration in micelles owing to a reduction in the surface potential and a change in the micellar structure and propertie s.
