The Uses of Phenylphosphine

Exposure to phenylphosphine may occur when phenylphosphinates (used as catalysts and antioxidants) are heated above 200°C, yielding phenylphosphonic acid derivatives and phenylphosphine.

The Uses of Phenylphosphine

It is mainly used as a precursor to other organophosphorus compounds. It can function as a?ligand?in coordination chemistry. Phenylphosphine also have uses in polymer synthesis.

General Description

Clear colorless liquid.

Air & Water Reactions

Pyrophoric in air. Insoluble in water. Slowly generates flammable or noxious gases in contact with water.

Reactivity Profile

Phenyl phosphine is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.

Health Hazard

Phenylphosphine is a respiratory and skin irritant; multiple exposures in rodents causes hematologic changes and testicular degeneration in males.

Fire Hazard

Flash point data are not available for Phenyl phosphine, but Phenyl phosphine is probably combustible.

Safety Profile

Poison by inhalation. Igmtes spontaneously in air. When heated to decomposition it emits toxic fumes of POx. See also PHOSPHINE.

Potential Exposure

Polyphosphinate is used as an intermediate or a chemical reagent. Polyphosphinate compounds are used as catalysts and antioxidants disproportionate, when heated to give phosphonic acid derivatives plus PF.

Shipping

UN2845 Pyrophoric liquids, organic, n.o.s Hazard Class: 4.2, Labels: 4.2-Spontaneously combustible material. Technical Name Required. Note: this chemical is also a strong reducing agent.

Incompatibilities

A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Water reactive; spontaneously combustible in high concentrations in moist air. Potential exposure to gaseous phenylphosphine and phosphorus oxides when heated above 200C. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
