Research on Synthesis Technology of Cinnamaldehyde by Aldol Reaction

Cinnamaldehyde is synthesized from the reaction of benzaldehyde and acetaldehyde with base as the catalyst.The factors affecting the quality and recovery of cinnamaldehyde,such as the catalyst,the temperature,the molar ration of the benzaldehyde and acetaldehyde are analyzed.The results show that at a temperature of 25 ℃,catalyst for sodium hydroxide,benzaldehyde∶ acetaldehyde = 3∶1 conditions,the yield of the product can reach 76%.
