4. 4 '- dihydroxy - 3, 3' - diamino benzophenone preparation method

The invention discloses a preparation method of 4,4'-dihydroxy-3,3'-diamino diphenyl ketone. The preparation method is characterized in that common organic reagents (chlorobenzene and parachlorobenzoyl chloride) are used as raw materials to prepare the target product through organic reactions in four steps. Particularly, pollution-free 4,4'-dichloro-3,3'-dinitro diphenyl ketone with high industrial application value is adopted to prepare 4,4'-dihydroxy-3,3'-dinitro diphenyl ketone which is a hydrolyzate, and 4,4'-dihydroxy-3,3'- diamino diphenyl ketone is prepared by using pollution-free hydrazine hydrate reducing method which is simple in process.
