10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

High concentration of the substance may ignite spontaneously on contact with air.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.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Spontaneously combustible in high concentrations in air. Potential exposure to gaseous PF when polyphosphinates are heated above 392F.

10.6 Hazardous decomposition products

The substance decomposes on heating producing toxic fumes including phosphorous oxides and phosphine.
