Kinetic study of the aminolysis of p-nitrophenyl acetate (PNPA) by hydrazine (HY) in the CTAB/chloroform/hexane reverses micelles has been carried out as a function of W {W = [H2O]/[CTAB]} and CTAB concentration. The reaction obeys first order kinetics with respect to each of the reactants in both media. The rate of reaction in reverse micelles decreases with increasing the value of W and observed rate constants are always lower than those for the corresponding reactions in aqueous solution under identical experimental conditions. The kinetic behavior was interpreted by using modified Berezin pseudo phase model, taking into consideration, distribution of the reactants, PNPA and hydrazine between the three pseudo phases, i.e, water pool, interface an organic phase.
