None
Synthesis method
Obtained from the condensation of benzoyl chloride and chlorobenzene: In a dry reaction pot, add chlorobenzene and anhydrous aluminum trichloride, stir and raise the temperature to 50°C, and add benzoyl chloride dropwise. After the addition, react at 100-110°C for 5.5 hours. Slowly add slightly acidic ice water, stir well and let it stand. Remove the supernatant, filter, wash until neutral, and spin dry to obtain 4-chlorobis. benzophenone.
Purpose
