摘　　要：以苯甲醛、乙酸酐为原料、KF/K2CO3为催化剂微波快速辐射,并用正交试验优选出最佳合成工艺条件:n(苯甲醛)∶n(乙酸酐)∶n(KF/K2CO3)=1∶3∶1.45,微波功率650W,反应6min,产率可达76.09%。Cinnamic acid is synthesized by microwave radiation with benzaldehyde and acetic anhydride as raw materials and KF/K_2CO_3 as catalyst.The optimal conditions obtained by orthogonal experiment are as follows: molar ratio of benzaldehyde, acetic anhydride and KF/K_2CO_3 is 1∶3∶1,45; power of microwave 650W; time of radiation 6 min.The yield of cinnamic acid reaches 76.09%.
