摘要
以钨锗杂多酸为催化剂，对肉桂酸与异戊醇的液相酯化反应进行了研究。考察了催化剂用量、反应时间、醇酸比、带水剂用量等对合成肉桂酸异戊酯的影响，得到合成该酯的较适宜条件。在相近条件下，不同醇的肉桂酸系列酯均可获较理想的酯化率。
Tungstogermanic heteropoly acid was used as the catalyst for the esterification of cinnamic acid with iso amyl alcohol in liquid phase.Effects of the amount of the catalyst used,the reaction time,the ratio of reactants and the amount of an agent which taking off water on synthesizing iso amyl cinnamate were investigated.A suitable condition for synthesizing the ester was obtained.More ideal esterification ratio of series cinnamates based on different alcohols has been obtained under similar condition.
