Abstract
4-Hydroxy-4′-chlorobenzophenone was synthesized through Friedel-Crafts acylation with anhydrous aluminium trichloride as catalyst,demethylation,and hydrolysis reactions from p-chlorobenzoyl chloride and anisole.The process was improved,and the orange crystal product was directly obtained from water solution at 40℃.The effects of amount of catalyst,amount of anisole,reaction temperature and reaction time on yield were examined.The optimal conditions were gained.The reaction process was reagent and time saving,and environmental pollution was reduced.
