What is phosphine oxide?

Phosphine oxides are phosphorus compounds with the formula OPX3. When X = alkyl or aryl, these are organophosphine oxides. Triphenylphosphine oxide is an example. An inorganic phosphine oxide is phosphoryl chloride (POCl3).

What is triphenylphosphine used for?

Besides it plays an important role in reactions of plant pigments. as an oxidation and UV stabilizer in plastics. In the dye industry, Triphenylphosphine is used as sensitizer, heat stabilizers, light stabilizers, antioxidants, flame retardants, antistatic agents, rubber antiozonants and analytical reagent.

What is the formula of phosphine?


How is phosphine manufactured?

Phosphine is made industrially from white phosphorus by hydrolysis with an alkali metal hydroxide or an aqueous acid–catalyzed disproportionation reaction. The industrial product is normally shipped as liquefied gas.

How is triphenyl phosphine prepared?

Triphenylphosphine (TPP) is prepared by reacting triphenylphosphine dichloride (TPPCl 2) with magnesium, aluminum and/or iron in the presence of an inert solvent, employing a TPPCl 2 solution whose content of phosgene, chlorine, diphosgene, hydrogen chloride, thionyl chloride, sulfuryl chloride, phosphorus trichloride.

Is triphenylphosphine soluble in hexane?

Triphenylphosphine oxide can be difficult to remove from reaction mixtures by means of chromatography. It is poorly soluble in hexane and cold diethyl ether.

What is the common name of triphenyl phosphine?
