Abstract: Benzaldehyde is used as a raw material, to synthesize cinnamaldehyde from acetaldehyde in catalysis by aldol condensation reaction. The conditions of the catalytic reaction were discussed. The product was characterized by GC-MS,IR and 1H NMR. The results show that: When the catalyst is Na2CO3/γ-Al2O3, the molar proportion of benzaldehyde and acetaldehyde is 1.3:1, the reaction temperature is 30 ℃, reaction time is 1 h, the amount of catalyst is 1 g (according to 11.6 g 40% acetaldehyde), the yield of cinnamaldehyde reaches 40.9%.

Key words: cinnamaldehyde, Na2CO3/γ-Al2O3, benzaldehyde, synthesize
