Triphenyl Phosphite (TPP) CAS 101-02-0 Purity >99.0% (GC) Factory

Triphenyl Phosphite (TPP) (CAS: 101-02-0) is also known as triphenoxytitanium phosphine, it is phosphite-based compound, it is a secondary antioxidant, it has light stabilizing effect, it is applicable to polyvinyl chloride, polypropylene, polystyrene, poly acetate, ABS resin, epoxy resin and the like. Triphenyl Phosphite is widely used as polyvinyl chloride chelating agent, when the metal soap is used as stabilizer, coordinating with this product can reduce the harm of the metal chlorides, it can keep transparency of product and inhibit the change in color. Further Triphenyl Phosphite is also used as flame retardant plasticizer. 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. Triphenyl Phosphite can be used: As a source of phosphorus and as a ligand for the synthesis of transition metal phosphide nanoparticles via heating-up process. To convert alcohols to alkyl halides. As a peptide coupling agent. As a low-temperature source of singlet oxygen after forming an adduct with ozone. It is used as an auxiliary antioxidant and can stabilizelight. It is suitable for polyvinyl chloride, polypropylene,polystyrene, polyester, ABS resin, epoxy resin, etc. Used as a chelating agent in polyvinyl chloride products to keep the product transparent and inhibit the color change. Used for the production of Trimethyl Phosphite. It can reduce the damage of metal chloridewith metal as the main stabilizer. Triphenyl Phosphite is a popular chelating agent that is widely applicable to various PVC products. It enables these PVC products to retain their transparency and inhibit color variance, while enhancing tlie anti-oxidation of main stabilizers and tlie properties of light and thermal stabilizers. Besides, it is applicable to PE, PP, ABS, SBS products and can function as a pesticide intermediate. Used as a pharmaceutical intermediate in the synthesis of 3-C-7 ACCA, Cephalosporin Drugs and Cefexime Formulation.

Production Methods: It can be obtained from phenol and phosphorus trichloride.
Reactivity Profile: Organophosphates, such as Triphenyl phosphite, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard: Triphenyl phosphite (TPP) is a skin irritant and sensitizer in humans and is neurotoxic in laboratory animals.Systemic effects have not been reported in humans.
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.
