【Abstract】 The catalytic processes were provide for simultaneous preparation of benzaldehyde and propionylchloride in the presence of ZnO/SnCl2. The reaction of 0.8 mol benzalchloride and 0.8 mol propanoic acid was carried out at 120-140℃ for 3 h to produce the mixture, then distilled to obtain benzaldehyde and propionylchloride with yield>90% and purity>98%.更多还原
