摘要
以香草醛和丙二酸为原料、乙酸铵为催化剂、DMF为溶剂、苯为带水剂,合成了阿魏酸。在V(苯)∶V(DMF)=2∶1、乙酸铵用量为6%(以香草醛质量计)、n(香草醛)∶n(丙二酸)=1∶1.4、反应时间为4h的优化条件下,阿魏酸产率达到71.02%。阿魏酸的抗氧化性实验结果表明,阿魏酸对食用油脂有一定的抗氧化能力,其在油脂中的抗氧化能力优于维生素E。
With vanillin and malonic acid as raw materials,ammonium acetate as catalyst, DMF as solvent,benzene as water-carrying agent,ferulic acid was synthesized.The optimal conditions were obtained as follows：the volume ratio of benzene to DMF was 2∶1,the dosage of catalyst was 6% of mass of vanillin,the molar ratio of vanillin to malonic acid was 1∶1.4,the reaction time was 4 h.Under above conditions,the yield of ferulic acid reached 71.02%.The antioxidant activity of ferulic acid was studied.The results showed that the antioxidant activity of ferulic acid for edible oil was better than that of vitamin E（VE）.
