| titleOfInvention | A kind of preparation method of o-fluorobenzoyl chloride |
| abstract | The invention discloses a preparation method of o-fluorobenzoyl chloride, comprising the following steps: (1) synthesis of o-fluorobenzoyl chloride: mixing o-fluorotoluene and triethanol, heating, adding azobisisobutyronitrile, and starting Feed into chlorine to obtain the intermediate o-trichlorobenzoyl chloride; (2) the synthesis of o-fluorobenzoyl chloride: the ortho-fluorobenzoyl chloride obtained in step (1) is heated up and kept under a slight negative pressure under stirring conditions, and slowly drips Add 0.5% zinc chloride aqueous solution, and drop it in 3 hours; if the o-fluorotrichloroben is not completely converted, then add dropwise zinc chloride aqueous solution until the o-fluorotrichloroben is completely converted, and then purify by vacuum distillation, and collect 100 ~ Distillate at 105°C to obtain o-fluorobenzoyl chloride. The preparation method of o-fluorobenzoyl chloride of the present invention has the advantages of less steps, high product yield and high purity. |
