| Use | Used as an intermediate in organic synthesis |
| Production method | Dissolve benzoyl chloride in carbon tetrachloride, add anhydrous ferric trichloride, and pass in chlorine under stirring. The reaction temperature is 35-50 ℃. After the reaction reaches the end point, the reactants are washed with water and dilute lye, dried, and distilled to recover carbon tetrachloride. Distillate under reduced pressure and collect the fraction at 137 ℃(2.0kPa) to obtain 2,5-dichlorobenzoyl chloride. |
