Usage

General Description

4,4'-DICHLORO-3,3'-DINITROBENZOPHENONE is a chemical compound that belongs to the class of benzophenone derivatives. It is a yellow crystalline solid that is used as a photoinitiator in the production of polymers and plastics. 4,4'-DICHLORO-3,3'-DINITROBENZOPHENONE has two chlorine and two nitro groups attached to the benzophenone backbone, making it a highly reactive and potent compound. It is commonly used in industries for UV-curable coatings, adhesives, and inks due to its ability to undergo photochemical reactions when exposed to ultraviolet light. However, it is important to handle this compound with care as it is toxic and harmful if ingested, inhaled, or in contact with the skin.

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.

Process for preparation of 3,3'- or 3,4'-diamino benzophenone

3,3'- or 3,4'-diamino benzophenone is prepared by catalytically reducing and dehalogenating, in the presence of a reduction catalyst and a dehydrohalogenation agent, a benzophenone compound or benzophenone compounds of the general formula STR1 in which X is a halogen atom at position 2 or 4 of the benzene ring and Y is hydrogen or a halogen atom and in which the nitro group is at position 3' or 4' of the benzene ring if Y is hydrogen, while Y is at position 4' and the nitro group is at position 3' of the benzene ring if Y is a halogen atom.
