Chlorodiphenylphosphine, referred to as CDPP, DPC, also known as diphenylphosphine chloride. It is an important intermediate

Uses: for organic synthesis, the conversion of alcohol into chlorinated hydrocarbons, ligands for complexation reaction with ammonia, preparation of phosphine oxide, thiol esters and vinylphosphine, reaction with lithium to synthesize lithium diphenylphosphide, used in organic synthesis and as an intermediate for pesticides, pharmaceuticals and dyes. It is widely used in the preparation of anti-UV agents, organophosphorus flame retardants, antioxidants, plasticizers and asymmetric synthesis catalysts.

Chlorodiphenylphosphine (CDPP) is one of the important raw materials for the production of photoinitiator TPO, and is also an important organophosphorus chemical product, which can also be used in the production of Chemicalbook, diphenylphosphine oxide, etc.; It is an important intermediate and is widely used in the preparation of anti-UV agents, organophosphorus flame retardants, antioxidants, plasticizers and asymmetric synthesis catalysts. At present, the method of industrial synthesis of Chlorodiphenylphosphine is from benzene and phosphorus trichloride as raw materials, catalyzed by anhydrous aluminum chloride, the generated diphenylphosphine chloride complexes with aluminum chloride, and dissociates diphenyl chloride by adding phosphorus oxychloride, dioxane, crushed sodium chloride or potassium chloride and trichloroaluminum.
