1 Alternatively, can be prepared by reaction of phosphoryl chloride with a controlled amount of water. 015-009-00-5. Phosphoryl chloride (8CI) Registration dossier . These esters have been used for many years as flame retardants and plasticisers for PVC. Phosphoryl chloride is a colorless liquid which fumes in air. Linear Formula POCl 3. Potassium chlorate can also be used as oxidizer, instead of pure oxygen. It is also used as a catalyst in organic synthesis. CAS number. Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3.With the freezing point of 1 °C and boiling point 106 °C, the liquid range is, incidentally, rather similar to water. It is used for production of agrochemicals, pharmaceuticals, dyes and flame retardants. In the semiconductor industry, Phosphory Chloride (POCl 3) is used as a safe liquid phosphorus source in diffusion processes. PubChem Substance ID 24855857. Structure, properties, spectra, suppliers and links for: Phosphoryl chloride, 10025-87-3, OPCl3, POCl3. When phosphoryl trichloride was used, the yield was 69%; in the case of phosphoryl tribromide, it was 72%. EC Number 233-046-7. It is also used in the production of other phosphorous compounds such as phosphorous pentachloride, phosphoryl chloride or thiophosphoryl chloride. Other identifiers. Structure: CAS Number: 10025-87-3 Molecular Weight: 153.33 g/mol Appearance: Colorless liquid Chemical Formula: POCl3 Melting Point: 1.25 C Boiling Point: 105.8 C Density: 1.645 g/mL Uses . 10025-87-3. Air is ineffective for this reaction. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. Chemical Name: Phosphorus Oxychloride / Phosphoryl Chloride Formula: POCl3 CAS Number: 10025-87-3 Molecular Weight: 153.3 General & Use: Phosphorus Oxychloride is used as a reagent in the production of organic phosphorus compounds. MDL number MFCD00011443. The formation of 4-thiatricyclo[3.2.1.0 3,6]octane 86 was demonstrated and yields varied slightly depending on the phosphoryl trihalide used. It is a raw material for producing organic phosphorus herbicide and chlordimeform, and it is a plasticizer in plastic production. 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. EC Inventory, C&L Inventory, Registration dossier, REACH pre-registration, Other, CAD - Chemical Agents Directive, Art. Uses: Phosphorous trichloride is used widely in chemical industry, mainly in the production of pesticides, surfactants, gasoline additives, plastics, medicinal products and textiles. C&L Inventory . It is mainly used to make phosphate esters such as tricresyl phosphate. Physical… Other names. Uses of Phosphory Chloride. The most important use for phosphoryl chloride is in the manufacture of triarylphosphate esters (as described above) such as triphenyl phosphate and tricresyl phosphate. Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3.It hydrolyses in moist air to phosphoric acid to release choking fumes of hydrogen chloride. Phosphorus oxychloride can be used as a semiconductor dopant, and it is a raw material for light-conducting fibers. Molecular Weight 153.33 . Phosphoryl chloride can be prepared by oxidizing phosphorus trichloride with pure oxygen, between 20-50 °C. NACRES NA.22 With the freezing point of 1 °C and boiling point 106 °C, the liquid range is rather similar to water. It is widely used in pesticides, pharmaceuticals, dyes, phosphates and flame retardant production. Index number.
