Product Introduction:

Triphenyl phosphite is abbreviated as TPP, additionally known as triphenoxyphosphine, which is a phosphite compound. It is an auxiliary anti-oxidant with light stabilization impact, appropriate for polyvinyl chloride, polypropylene, polystyrene, polyester, abdominal muscle material, epoxy material, and so on.

Below room temperature level, it is colorless to pale yellow monoclinic crystal. Over area temperature, it is a colorless light yellow clear oily fluid with a poignant odor. Insoluble in water, soluble in ethanol, ether, acetone, benzene as well as other organic solvents.

Triphenyl phosphite is a prominent example of polymorphism in organic compounds, i.e. it exists in two different amorphous forms at temperatures around 200 K. Not long ago, a research team obtained a long-awaited new polymorphic modification of triphenyl phosphite by crystallization in ionic liquids.

Product Usage:

Triphenyl phosphite (TPP) as a raw material for natural chemicals has a vast array of uses. Usual uses are as follows:

  1. Antioxidant as well as stabilizer TPP is mainly used as antioxidant stabilizer for polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyester, abdominal muscle material, epoxy material, artificial rubber, etc
  2. It is used as a flame resistant plasticizer for nitrocellulose, cellulose acetate movie (such as film base) and film plastics, and can also be made use of as a non-flammable replacement for camphor in viscose fiber.
  3. Triphenyl phosphite is an antioxidant for polyvinyl chloride plastics as well as a raw material for alkyd resins and chemical intermediates. As a fire retardant plasticizer for cellulose resins, plastic materials, natural rubber and also artificial rubber.
  4. When used along with halogen flame retardants, it can apply its fire retardant as well as antioxidant results, and has light stablizing function.
  5. It is likewise extensively used as a chelating agent for polyvinyl chloride. When a stabilizer based upon metal soap is made use of, this item can reduce the injury of steel chloride. Low toxicity, can be made use of in plastic medical gadgets. And can maintain the openness of the item and also hinder the modification of its chromaticity.
  6. It is utilized in engineering plastics and also phenolic materials, and also used in combination with halogen-based flame retardants, which can play a role in flame resistant and also anti-oxidation. It has both light stability and is likewise a crucial intermediate for the prep work of trialkyl phosphite.
  7. In addition, it is additionally made use of as a flame retardant plasticizer. Phenyldiisooctyl phosphite is obtained by transesterification of triphenyl phosphite and also isooctanol in the visibility of a driver. Phenyldiisooctyl phosphite can be made use of as an auxiliary antioxidant.
  8. Utilizing this item in the existence of salt methoxide, it can be transesterified with methanol to create trimethyl phosphite. Using triphenyl phosphite as basic material and also responding with octanol in sodium methoxide service, octyl diphenyl phosphite can be prepared.
