Mono-cinnamyl maleate was prepared by esterification of maleic anhydride and cinnamyl alcohol of 1 mol:2 mol at 95 ℃ for 2～4 h.Then added isomeric catalyst and mono-cinnamyl fumarate was made by reacting at 90 ℃ for 4 h.After methanol (methanol:mono-cinnamyl fumarate = 6 mol:1 mol) was added,the mixture maintained at 90 ℃ for 4.0 h to synthesize CMF.

合成试验表明：以摩尔比为1：2的马来酸酐与肉桂醇在95 ℃醇解反应2～4 h后加入异构化催化剂，90 ℃转型反应4 h后，添加6倍摩尔质量的甲醇，在90 ℃恒温反应4 h，反丁烯二酸桂醇甲酯的合成产率较高。

Cinnamaldehyde, a member of α,β-unsaturated aldehydes, and its semi- hydrogenated products such as cinnamyl alcohol and hydrocinnamaldehyde are important fine chemicals and intermediates especially in perfume industry and medicine manufacture.

肉桂醛是α，β-不饱和醛分子中的一种，肉桂醛分子中C=C键及C=O键加氢生成半加氢产物加氢肉桂醛和肉桂醇更是医药、香料等的重要原料及中间体。
