When phosphoryl trichloride was used, the yield was 69%; in the case of phosphoryl tribromide, it was 72%. Preparative Methods: prepared in 30% yield by heating Phosphorus(V) Oxide and Phosphorus Oxychloride in a sealed tube and separating the resulting mixture by fractional distillation. NACRES NA.22 10025-87-3. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. Phosphorus oxychloride can be used as a semiconductor dopant, and it is a raw material for light-conducting fibers. 1 Alternatively, can be prepared by reaction of phosphoryl chloride with a controlled amount of water. MDL number MFCD00011443. PubChem Substance ID 24855857. Phosphoryl chloride (8CI) Registration dossier . Other identifiers. Physical… Synonym: Phosphorus(V) oxide chloride, Phosphoryl chloride CAS Number 10025-87-3. It is widely used in pesticides, pharmaceuticals, dyes, phosphates and flame retardant production. It is also used as a catalyst in organic synthesis. Phosphoryl chloride is a colorless liquid which fumes in air. Potassium chlorate can also be used as oxidizer, instead of pure oxygen. 015-009-00-5. Molecular Weight 153.33 . 2 PCl 3 + O 2 → 2 POCl 3. Air is ineffective for this reaction. It is also used in the production of other phosphorous compounds such as phosphorous pentachloride, phosphoryl chloride or thiophosphoryl chloride. Index number. Phosphoryl chloride can be prepared by oxidizing phosphorus trichloride with pure oxygen, between 20-50 °C. The most important use for phosphoryl chloride is in the manufacture of triarylphosphate esters (as described above) such as triphenyl phosphate and tricresyl phosphate. C&L Inventory . Uses . It is a raw material for producing organic phosphorus herbicide and chlordimeform, and it is a plasticizer in plastic production.
