摘要
用阿魏酸与无水乙醇在酸催化下直接酯化反应合成阿魏酸乙酯,通过红外谱图和气-质联用谱图证实了阿魏酸乙酯的结构,并通过正交实验确定了合成阿魏酸乙酯的最佳条件为:n(阿魏酸)∶n(无水乙醇)=1∶6;反应时间为8 h;n(催化剂)∶n(阿魏酸)=1∶4,产品为无色固体。
Using ferulic acid reaction with anhydrous ethanol, catalyzed by acid make ethyl ferulate, Via IR and GC-MS chart, it can be got that the configuration and confirm the best condition of ethyl ferulate. And decide the best condition of synesis of ethyl ferulate. By orthogonality conditions： the ratio of ferulic acid and anhydrous ethanol is 1 ： 6, time is 8 h , the ratio of catalyzer and ferulic acid mol 1/4. pruduct is achromatic solid.
