Triphenylphosphine is widely used in chemical industry.

Triphenylphosphine is first sulfonated with oleum to form the trisulfonic acid.

Triphenylphosphine can be used in Wittig synthesis. It is a standard ligand in homogeneous catalysis.

Triphenylphosphine is used in the synthesis of an organophosphorus intermediate, trimethyl phosphite in ester exchange method. And then a series of organophosphorus pesticides such as dichlorvos, monocrotophos and phosphamidon can be further obtained.

In addition, it can be used as stabilizers in the synthesis of rubber and resins, antioxidants in polyvinyl chloride, and raw material in the synthesis of alkyd resins and polyester resins.

Triphenylphosphine finds applications in the following fields, among others:

Synthesis

Pharmaceutical and crop protection active ingredients

Vitamin synthesis

Reagent for organic chemical reactions, among others Wittig, Mitsunobu, Heck or Suzuki reactions

Catalysis

Co-catalyst hydroformulation processes, offering additional value to our customers due to our high purity.

Ligand for hydrogenation catalysis

Polymers

Curing agent for powder coatings or in UV curing coatings

Additive for the oxidation of UV stabilization of plastics
