摘 要: 以α,β-不饱和羰基结构为母体设计合成反丁烯二酸桂醇甲酯(CMF),并对反丁烯二酸桂醇甲酯的抗菌活性进行了研究。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。4h后加入异构化催化剂,90℃转型反应4h后,添加6倍摩尔质量的甲醇,在90℃恒温反应4h,反丁烯二酸桂醇甲酯的合成产率较高。皮肤刺激性试验表明:CMF对皮肤无致敏性。抗菌活性试验表明:反丁烯二酸桂醇甲酯不但杀菌谱广,而且有效作用浓度低,在食品加工、保藏中具有广阔的开发应用前景。 Synthesis technology of cinnamyl methyl fumarate (CMF) containing α, β-unsaturated carbonyl group and its antimicrobial activity was studied. Mono-cinnamyl maleate was prepared by esterification of maleic anhydride and cinnamyl alcohol of 1 tool :2 mol at 95℃for 2 -4 h. Then added iso- meric 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. Skin test indicated that CMF has no cutaneous anaphylaxis. Antimicrobial study showed that CMF could remarkably inhibit the growth of mold, yeast and bacteria. These suggested CMF was a preservative worth of developing and applying largely in food processing.
