Abstract

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.

杯芳烃含胆碱基团在酯水解过程中的催化性能
对杯[4]芳烃与胆碱基团的催化性能的研究表明,在硼酸水溶液中,4-硝基苯基乙酸酯和4-硝基苯基棕榈酸酯的水解反应初始速率显著增加。对4-硝基酚酯的加速作用达到200倍,超过阳离子表面活性剂十六烷基三甲基溴化铵和n -十六烷基氯化吡啶一个数量级以上。分析了杯芳烃聚集体在溶液中的结构及其对水解反应速率的影响。
