| Abstract: | p-Fluorobenzoylchloride was synthesized with p-fluorotoluene by photochlorination,hydrolysis and vacuum distillation.In the presence of visible light and side-reaction inhibitor,p-fluorotoluene reacted with chlorine at 125-145 ℃,the yield of p-fluorobenzotrichloride was 94.8%;p-fluorotoluene reacted with water at 120 ℃,the mole ratio of water to p-fluorobenzotrichloride was 0.98∶1,the yield of p-fluorobenzoyl chloride was 91.5%,the total yield of p-fluorobenzoyl chloride was 86.7%.The structure of target product was identified by IR,MS and 1H NMR. |
