Abstract

The kinetics of the aminolysis of ethyl p-nitrophenyl carbonate (ENPC) by dodecylamine (DA), dodecylammonium diethylarsinate (DADEA; dry aggregates and in the presence of solubilized water), and DA plus dry DADEA in chloroform were studied spectrophotometrically. Addition of 0.20 M of the surfactant enhances the rate of aminolysis by DA by a factor of 28.3 due to bifunctional catalysis by the former. In the aminolysis by ...
