摘　　要：以苯甲醛和正丙醛为原料,KF/Al_2O_3为催化剂,聚乙二醇为相转移溶液,合成了α-甲基肉桂醛,考察了原料摩尔比、反应时间、反应温度、催化剂用量等对收率的影响,确定了最佳反应条件。α- Methylcinnamaldehyde was synthesized from benzaldehyde and n - propylaldehyde using KF/ Al2O3 as catalyst and polyethylene glycol as phase transfer solution. The influences of molar ratio of benzaldehyde to n - propylaldehyde, reaction time, reaction temperature, and dosage of catalyst on the yield of α- methylcin-namaldehyde were investigated. The optimum reaction conditions were obtained.
