The catalytic efficiencies of phenyl-and 2, 4-dimethoxyphenylcetyldimethylammonium bromides (CPDA and CDPDA) are greater than that of cetyltrimethylammonium bromide (CTABr) for the spontaneous hydrolyses of the dianions of 2, 4-and 2, 6-dinitrophenyl phosphates, the reactions of hydroxide and fluoride ions with p-nitrophenyl diphenyl phosphate, and the reaction of hydroxide ion with 2, 4-dinitrochlorobenzene in water, ...
