Description
Phosphorus trichloride is a colorless to pale yellow transparent liquid with a pungent and foul odor. It is volatile, highly corrosive and toxic. It is prone to hydrolysis in moist air, generating hydrogen chloride fumes. It decomposes to produce toxic gases when exposed to open flames or high temperatures. As an important intermediate in organic synthesis and chemical production, it possesses strong reducibility.

Safety, Security & Risk
Physical Hazards
Vapor is heavier than air.
Chemical Hazards
When heated, it decomposes to generate toxic and corrosive fumes containing hydrogen chloride and phosphorus oxides. It reacts with oxidizing agents. It reacts violently with water, generating heat and decomposition products including hydrochloric acid and phosphoric acid, which presents fire and explosion hazards. It also reacts violently with alcohols, phenols and alkalis, and corrodes metals and many other materials.
