| Introduction | diphenylphosphine chloride (CDPP) is one of the important raw materials for the production of photoinitiator TPO, its synthesis is obtained by the Friedel-Crafts reaction of benzene and phosphorus trichloride under the catalysis of aluminum trichloride. Because aluminum trichloride will form a complex with the product after the reaction, therefore, it is necessary to add sodium chloride to free the product CDPP, which will produce a large amount of solid waste of sodium tetrachloroaluminate. This part of the solid slag has a large odor due to the very small amount of CDPP, and about 3 t of solid slag is produced per 1 t of CDPP, so how to deal with the solid waste reasonably is an urgent problem to be solved by CDPP production enterprises. |
| Application | diphenylphosphine chloride (CDPP) is one of the important raw materials for the production of photoinitiator TPO, is also an important organic phosphorus chemical products, industrial can also be used for production, diphenyl phosphine oxide, etc.; Is an important intermediate, widely used in the preparation of anti UV agent, organic phosphorus flame retardant, antioxidant, plasticizers and catalysts for asymmetric synthesis. |
| synthesis method | at present, the industrial synthesis method of diphenyl phosphine chloride is the reaction of benzene and phosphorus trichloride as raw materials under the catalysis of anhydrous aluminum chloride, the resulting diphenylphosphorus chloride is complexed with aluminum trichloride and The diphenyl chloride is dissociated by reaction with aluminum trichloride by adding phosphorus oxychloride, dioxane, crushed sodium chloride or potassium chloride. |
| Use | for organic synthesis and as pesticides, The introduction of diphenyl phosphorus in the Lithiation Reaction in the synthesis of pharmaceutical and dye intermediates. |
| autoignition temperature | 320°C |
