DESCRIPTION

DESCRIPTION

Chemical Properties:

Triphenyl Phosphite is colorless to pale yellow monoclinic crystal below room temperature. It is colorless light yellow transparent oily liquid at room temperature or higher, it has pungent odor. It is insoluble in water, soluble in organic solvents such as ethanol, ethyl ether, acetone, benzene and the like.

Phosphite phenyl diisooctyl can be obtained by the transesterification reaction of triphenyl phosphite and isooctanol in the presence of catalyst, phosphite phenyl diisooctyl can be used as secondary antioxidant. It has good resistance to discoloration, it can increase oxidation resistance and light stability. It has chelating action in PVC, low toxicity, it can be used in plastic medical devices.

In addition, this product in the presence of sodium methoxide can proceed the transesterification reaction with methanol to form trimethyl phosphite.

Triphenyl phosphite is as raw material, it can react with octanol in the solution of sodium methoxide, octyl diphenyl phosphite can be prepared.


Production Methods:

Triphenyl Phosphite can be obtained from phenol and phosphorus trichloride.


Safety Profile:

Poison by intraperitoneal and subcutaneous routes. Moderately toxic by ingestion. An experimental eye and severe human skin irritant. Combustible when exposed to heat or flame. To fight fire, use CO2, mist, dry chemical. When heated to decomposition it emits toxic fumes of POx. See also PHENOL.

APPLICATION

APPLICATION

  • Triphenyl phosphite is used as chelating agents, plastics antioxidant, alkyd resin and pesticide intermediate raw material.

  • It is used for synthetic rubber and resin stabilizer, PVC antioxidant, alkyd resin and pesticide intermediate raw material.

  • Triphenyl phosphite is used as secondary antioxidants, it has effect of light stability, it is suitable for polyvinyl chloride, polypropylene, polystyrene, polyester, ABS resin, and epoxy resin.

  • It is used as chelating agent in PVC products, it can enable products to maintain transparency, and suppresse color change. It can also be used for the production of trimethyl phosphite.

  • Antioxidants, stabilizers TPPi is mainly applied to polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyester, ABS resin, epoxy resin, synthetic rubber antioxidant stabilizer for PVC vinyl products as chelating agent, when the metal is as based stabilizer, coordinating with the product can reduce the harm of metal chloride

  • Chelating agent. Plastic products antioxidant. The synthesis of alkyd resins and polyester resins.

  • Chelating agent, it is widely used in all kinds of PVC products, it can enable products to maintain its transparency and suppress color change, and it can increase the antioxidant and light and heat stability of the primary stabilizer. In addition, the product is also used for PE, PP, ABS, SBS and other products, and it can be used for pesticide intermediates. It can be used for synthetic alkyd resins and polyester materials and polyester resins.
