Functionalized surfactant mediated reactions of carboxylate, phosphate and sulphonate esters
Original language description
Nucleophilic reactivity of some functionalized surfactants, i.e. quaternary pyridinium aldoximes towards the hydrolysis of p-nitrophenyl acetate (PNPA), p-nitrophenyl benzoate (PNPB), p-nitrophenyldiphenyl phosphate (PNPDPP) and p-nitrophenyl p-toluene sulphonate (PNPTS) has been studied at pH 7.1 and 27 -C. Addition of functionalized surfactant to reaction medium causes progressive increase in the rate of hydrolysis and reaches a maximum and then decreases due to further addition of surfactant. An increase in the alkyl chain length of functionalized surfactants resulted in an increase in the first-order rate constant. The apparent pKa and cmc of functionalized surfactants have also been determined by spectrophotometric and conductometric methods, respectively.
