4,4'-Dihydroxybenzophenone Production
Ph(CO2)Ph → (HOC6H4)2CO
The preparation method of 4,4`dihydroxybenzophenone includes rearranging Ph p-hydroxybenzoate in the presence of catalyst at a molar ratio of 1:(0.1-1) in organic solvent at 70-170?C for 3-20 h; separating; and recrystalizing. to obtain 4,4'-dihydroxybenzophenone, wherein Ph p-hydroxybenzoate is prepared. by acetylating p-hydroxybenzoic acid to generate p-acetoxybenzoic acid; chlorinating to generate p-acetoxybenzoyl chloride; and reacting with PHENOL and deacetylating to obtain Ph p-hydroxybenzoate.
