PHOSPHORUS OXYCHLORIDE

CAS No. 10025-87-3
Phosphorus Pentachloride

Product Features

Phosphorus Oxychloride is used in the manufacture of phosphate esters widely used in plasticizers, hydraulic fluids, lube oil additives, pesticides, and flame retardants. It can be a catalyst, chlorinating agent, and solvent in cryoscopy, intermediate for dyestuffs, extraction agent for uranium, cross-linking agent or doping source.

Specification

Phosphorus Oxychloride is a colorless or slightly yellow fuming liquid with a pungent odour. It is toxic and corrosive, soluble in several common organic solvents. Reacts violently with water. Incompatible with strong oxidizing agents, alcohols, bases (including amines). Stable under normal conditions of use and storage.

Application

  • MANUFACTURE OF ESTERS

    Phosphorus Oxychloride is used in the manufacture of Phosphate Esters. The esters are widely used in plasticizers for PVC, non-flammable hydraulic fluids, lube oil additives, pesticides, and flame retardants. Tri aryl phosphate esters such as Tri Phenyl Phosphate and Tri Cresyl Phosphate are used as flame retardants and plasticizers for PVC. Meanwhile tri alkyl esters such as Tri Butyl Phosphate are used as liquid-liquid extraction solvents.

  • PHARMA

    Phosphorus Oxychloride is used in the manufacture of several pharmaceuticals. For example, it is applied in chlorination reaction of long-valid p-amino benzene sulfonamide medicines.

  • ELECTRICAL INDUSTRY

    Phosphorus Oxychloride is primarily used as a safe liquid phosphorus source for N-type doping in the fabrication of IC, solar cell and some semiconductor discrete components. The phosphorus acts as a dopant used to create N-type layers on a silicon wafer.

  • AGROCHEMICALS

    Phosphorus Oxychloride is used in the production of organic phosphorus pesticide like herbicides and insecticides. Phosphorus Oxychloride is widely used in producing materials of organic-phosphorus pesticide kill-grass agent (e.g. chlordimeform hydrochloride).

  • DEHYDRATING AGENT

    In the laboratory, Phosphorus Oxy Chloride is widely used as a dehydrating agent, for example for the conversion of amides to nitriles. Similarly, certain aryl amides can be cyclised todihydroisoquinoline derivatives using the Bischler-Napieralski reaction. For example pyridones and pyrimidonescan be converted to chloro-derivatives of pyridines and pyrimidines, which are important intermediates in the pharmaceutical industry.

OTHER USES

  • Stuff of forming high-purity phosphoric acid.
  • Catalyst and chlorinating agent in the synthesis of target molecules.
  • Solvent in cryoscopy.
  • Cross-linking agent for starch.
  • Extraction agent for uranium ore.
  • Anti-refraction doping source (in optical fiber).
