摘要：
The differences between the hydroxyalkylated surfactants and their trimethylammonium analogues observed in a course of the p-nitrophenylacetate hydrolysis reaction are due to the hydrogen bonding of the hydroxyalkyl substitutor with the substrate. From one side, decylamine, being introduced to the system, shows up as the nucleophilic reactant responsible for the aminolysis contribution to the total p-nitrophenylacetate destruction rate. On the other hand it facilitates micellization in the system via the mixed aggregates formation.
