微波辐射KF/K_2CO_3催化合成肉桂酸

Synthesizing cinnamic acid by KF/K_2CO_3 catalyst cealed with microwave radiation

通过对KF/K2CO3催化合成肉桂酸反应的研究,发现在该反应中,KF/K2CO3催化性能较好,用微波处理后使用效果更佳.当反应温度为160℃,m(KF):m(K2CO3)=1:2,n(苯甲醛):n(乙酸酐):n(KF/K2CO3)=1:3:1.45,KF/K2CO3用微波处理2min,肉桂酸产率高达85.5%.

Probing into the reaction of synthesizing the cinnamic acid by KF/K2CO3, we find that KF/K2CO3 is active and it can be better after dealed with microwave. When m（KF）： m（K2CO3） was 1：2, n（（benzaldehyde）： n（acetyl oxide）： n（KF/K2CO3） was 1：3：1.45, the catalyst is treated by microwave for 2 rain, the yield of the cirmamic acid is as high as 89.8% at 160℃.
