Phosphorus trichloride

Phosphorus trichloride is a colorless to pale yellow, fuming liquid with a pungent, irritating odor and high volatility; it melts at –93.6 °C and boils at 76.1 °C. It is an inorganic chlorinated phosphorus compound classified as a reactive chemical intermediate. Industrially, it serves primarily as a key precursor in the synthesis of phosphorus-containing compounds, including phosphorus oxychloride, phosphonic acids, and organophosphorus derivatives. Its principal applications are in the production of agrochemicals (e.g., herbicides and insecticides), flame retardants, plasticizers, and pharmaceutical intermediates.

Phosphorus trichloride is used to prepare phosphine and other phosphorus compounds; used during electrodeposition of metal on rubber and for making pesticides, surfactants, gasoline additives, plasticizers, dyestuffs, textile finishing agents, germicides, medicinal products, and other chemicals.
A colorless or slightly yellow fuming liquid with a pungent and irritating odor resembling that of hydrochloric acid. Causes severe burns to skin, eyes and mucous membranes. Very toxic by inhalation, ingestion and skin absorption. Reacts with water to evolve hydrochloric acid, an irritating and corrosive gas apparent as white fumes.
