About:
Diphenylphosphine chloride (CDPP) is one of the important raw materials for the production of photoinitiator TPO. Its synthesis is obtained through the Fouke reaction of benzene and phosphorus trichloride under the catalysis of aluminum trichloride. Since aluminum trichloride will form a complex with the product after the reaction, it is necessary to add the complexing agent sodium chloride to free the product CDPP. This will produce a large amount of sodium tetrachloroaluminate solid waste, this part of the solid waste because it contains a very small amount of CDPP resulting in a larger odor, and each production of 1tCDPP produces about 3t solid waste, so how to reasonably dispose of the solid waste is an urgent problem to be solved by CDPP manufacturers.

Applications:
Diphenylphosphine chloride (CDPP) is one of the important raw materials for the production of photoinitiator TPO, and also an important organic phosphorus chemical product. It can also be used in the production of diphenylphosphine oxide in industry. It is an important intermediate, widely used in the preparation of anti-UV agents, organophosphorus flame retardants, antioxidants, plasticizers and asymmetric synthesis catalysts.
