摘　　要：以苯甲醛、乙醛为原料,在碱性条件下用羟醛缩合法合成产物肉桂醛,并分别考察了催化剂、反应温度、两种原料用量比对产物收率的影响。结果表明:在温度为25℃、催化剂为氢氧化钠、苯甲醛∶乙醛=3∶1的条件下,产品收率能达到76%。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%.
