| Abstract: | The synthetic process of 2, 4 - dichloro- 5 - fluoroacetophenone was studied. Using 2, 4 - dichloro fluorobenzene and acetyl chloride as materials, AlCl3 as catalyst, the product was obtained by solvent extraction, distillation and crystallization. The optimum processing parameters such as material ratio, temperature and reaction time were determined through experiments. Solvent A was selected as extraction agent. The yield of product can reach 80%. |
