General Description

A solid.

Air & Water Reactions

Slowly reacts with water to form phosphorous acid and trimethylol, an alcohol.

Reactivity Profile

TRIMETHYLOLPROPANE PHOSPHITE is a phosphite ester. May react with strong reducing agents such as hydrides to form highly toxic and flammable phosphine, a gas. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
