Study on the Catalytic Synthesis of Trans-ferulic Acid by KF/K2CO3/γ-Al2O3
摘要
Abstract
[Objective] To study the catalytic synthesis of trans-ferulic acid by KF/K2CO3/γ-Al2O3 from vanillin and maionic acid using KF/ Al2O3 as a catalyst. [Method] The trans-ferulic acid was catalytically synthesized from vanillin and maionic acid using KF/K2CO3/7-Al2O3 as a catalyst by Knoevenagel condensation reaction. The factors influencing the yield of trans-ferulic acid was investigated, including reaction time, monomer ratio of vanillin to maionic acid and catalyst dosage, [ Result] The optimum conditions for catalytic synthesis were found as follows: 7.6 g(0.05 mol) vanillin, n ( Vanillin): n (maionic acid) = 1:1.20, 1, 00 g KF/K2CO/γ-Al2O3, 25 ml n-Butyl acetate, and 2 h reaction time. The yield of trans-ferulic acid was above 65 % , and catalyst was used for 6 recycles, the yield of trans-ferulic acid was still above 60 %. [Conclusion] KF/K2CO3/γ-Al2O3 has good catalytic activity.关键词
