摘 要:以阿魏酸乙酯和异辛醇为原料,对甲基苯磺酸为催化剂,经酯交换反应合成阿魏酸异辛酯.分别考察物料配比、反应温度、反应时间及催化剂用量等对合成反应的影响,并采用核磁共振氢谱和红外光谱确定产物结构.实验结果表明:在阿魏酸乙酯0.02 mol,异辛醇、阿魏酸乙酯和对甲基苯磺酸的量的比为8∶1∶0.1,反应温度80℃,反应时间10 h的合成最优条件下,阿魏酸异辛酯产率为72%.Ferulic acid 2-ethylhexyl ester was synthesized from ferulic acid ethylester and isooctanol through interesterification using p-toluenesulfonic acid as a catalyst and isooctanol as a solvent. The factors such as the ratio of feed, reaction temperature, reaction time and the amount of catalyst on the synthesis reaction were investigated. The structure of the product was characterized by 1H NMR and IR. Results showed that the final yield of ferulic acid 2-ethylhexyl ester was 72 % under the optimum conditions as follows: the ratio of feruic acid ethylester, isooctanol and p-toluenesulfonic acid was 1 : 8 : 0. 1 when the initial ferulic acid ethylester was 0. 02 mol.
