相转移催化合成羧酸苄酯

Synthesis of carboxylic acid benzylester by phase transfer catalysis

以[C6H5CH2N（C2H5）3]Cl为相转移催化剂，用于羧酸钠和苄基氯之间的亲核取代反应合成了六种羧酸苄酯。研究了催化剂的用量、反应时间、反应温度、搅拌速度等因素对反应结果的影响，提出了合成羧酸苄酯的最佳反应条件。

In this paper, [C6H5CH2N(C2H5)3]Cl was applied to the nudeophilic substitution reaction of sodium carboxylate with benzyl chloride, six kinds of carboxylic acid benzylester were synthesized.The reaction factors (amount of catalyst, reaction time, reaction temperature and mix speed, etc.),which influence the reaction result were studied, and the best reaction conditons determined.
