Rapid Synthesis of Cinnamic Acid by Microwave Radiation

Zhang Xin-bing

Abstract

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%.
