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
