Production method | Benzene and carbon tetrachloride are condensed (F-K reaction). Add aluminum trichloride and 2/3 amount of anhydrous carbon tetrachloride to the reaction tank, cool to 10-15 ℃, add 1/12 amount of benzene to react, continue to cool to 5-10 ℃, add the remaining mixture of carbon tetrachloride and benzene dropwise, add it, and react at 10 ℃ for 3 hours. |
