摘要
The kinetics of the hydrolysis of p-nitrophenyl benzoate (PNPB) and p-nitrophenyldiphenylphosphate (PNPDPP) by hydroxamate ions (R'(C=O)N(RO-) have been investigated in aqueous cationic micellar media at pH 6.5 to 12.0 and 27 degrees C. The pseudo-first order rate constants-surfactant profiles show micelle assisted bimolecular reaction involving an interfacial exchange between bulk aqueous media and micellar pseudophase. All the hydroxamate ion shows higher reactivity in cationic micellar media. Pseudophaie model has been applied in order to determine micellar second order rate constant and binding constant.
