Triphenyl phosphite Uses

Chemical intermediate, stabilizer systems for resins, metal scavenger, diluent for epoxy resins.

Triphenyl phosphite Production

Triphenyl phosphite is prepared from phosphorus trichloride and phenol in the presence of a base:
PCl₃ + 3 HOC₆H₅→ P(OC₆H₅)₃ + 3HCl
Trimethyl phosphine is prepared from triphenylphosphite:
3 CH₃MgBr + P(OC₆H₅)₃ → P(CH₃)₃ + 3 MgBrOC₆H₅

Triphenyl phosphite Specification

Triphenyl phosphite , with CAS number of 101-02-0, can be called phosphorous acid, triphenyl ester ; Advance TPP ; Phenyl phosphite ; Sumilizer TPP-R ; Trifenoxyfosfin ; Tris(phenoxy)phosphine . It is a colourless to pale yellow liquid, be insoluble in water. Triphenyl phosphite (CAS NO.101-02-0) are susceptible to form highly toxic and flammable phosphine gas in the presence of strong reducing agents, such as hydrides. Partial oxidation may result in the release of toxic phosphorus oxides.
