摘要
本文阐述了合成苯甲酸苄酯中采用相转移催化的基本原理和方法,考察了反应时间,原料的配比和催化剂用量对苯甲酸苄酯重量产率的影响,得出在反应时间为2.5h,原料配比为1:1.2(摩尔比),每个摩尔苯甲酸钠加水100ml,催化剂用量为苯甲酸钠摩尔数的10%时,其苯甲酸苄酯产率为88.05—91.20%。
Inrelation to the synthesis of benzyl benzoate by phase transfer catalysis,the authors study its basic principle and method,and inspect the influences of reaction time,raw material proportioning, and catalyst consumption on the output rate in weight of benzyl benzoate.The results reveal a raw ma- terial proportioning of 1:1.2 molar ratio for a reaction time of 2.5 hours,to each mole of sodiurn ben- zoate should add distilled water 100ml;and a benzyl benzoate output rate of 88.05-91.20% for a catalyst consumption of 10% sodium benzoate mole number.
