摘要
用氯化四正丁基铵作为相转移催化剂，对缩合法合成乙酸苄酯工艺进行改进。试验研究了反应物配比、催化剂用量及反应温度、反应时间等因素对缩合反应的影响。该法具有反应温度低、速度高等优点，收率可达９６％以上。尤其重要的是，新工艺不必在无水条件下进行，简化了合成工艺，又能使产品质量稳定。
A technological improvement was made on the synthesis of benzyl acetate by the condensation reaction with n tetrabutylammonium chloride as the phase transfer catalyst. The effects of the reactants, amount of catalyst, temperature and time of reaction on the condensation were investigated. The product quality was stable and the recovery could be up to 96% or more by the method featured of the low reaction temperature and fast rate, especially simplified process which was in progress without water.
