Product Details

Triphenylphosphine CAS#603-35-0

Triphenylphosphine is a common organophosphorus compound with the formula P(C6H5)3 - often abbreviated to PPh3 or Ph3P. It is widely used in the synthesis of organic and organometallic compounds. PPh3 exists as relatively air stable, colorless to pale yellow monoclinic crystals at room temperature. It is a colorless to pale yellow transparent oily liquid above the room temperature with skin irritation and a pungent odour. It dissolves in non-polar organic solvents such as benzene and diethyl ether.

Product Application of Triphenylphosphine CAS#603-35-0

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.
