三相催化法合成乙酸苄酯的研究

STUDY OF THE SYNTHESIS OF BENZYL AVETATE CATALYZED BY TRIPHASE TRANSFER CATALYST

本文用三相催化法由氯化苄和乙酸钠水溶液一步合成乙酸苄酯。考察了反应时间、反应物配比、催化剂用量、催化剂种类、加水量等因素对反应产率的影响。在最佳反应条件下乙酸苄酯的产率可达96％以上。

Benzyl acetate has been synthesised by the direct reaction of benzyl chloride and sodium acetate solution catalyzed by triphase transfer catalyst. The correlation between the product yield and the catalyst amout, kind of catalyst, ratio of reactannt, water doses, have been studied. Under optimum condition the yield of benzyl acetate for 3 hours at boiling is over 96%.
