Kinetic study on the effects of inert salts on pH-independent hydrolysis of phthalimide in mixed nonionic-ionic and ionic-ionic micelles

摘要

Pseudo first-order rate constants, k(obs), for pH-independent hydrolysis of phthalimide in the presence of constant [mixed micelles] and varying values of [MX], Where MX represents inert salts C6H5CO2Na, C6H5OCH2CO2Na and NaBr, follow the empirical relationship: k(obs) {k(0) + 0 K [MX]}/{1 + K [MX]} where 0 and K are empirical constants and k(0) = k(obs) at [MX] = 0.
