Catalytic Properties of Calixarene Bearing Choline Groups in the Processes of Ester Hydrolysis
The study of catalytic properties of calix[4]arene with choline groups has shown a significant increase in the initial rate of a hydrolysis reaction of 4-nitrophenyl acetate and 4-nitrophenyl palmitate in aqueous borate buffer solutions. The acceleration for 4-nitrophenol ester reaches 200 times and exceeds the effect of cationic surfactants cetyltrimethylammonium bromide and N-cetylpyridinium chloride more than an order of magnitude. The structure of calixarene aggregates in solutions and the nature of their influence on the rate of hydrolysis reactions have been analyzed.
