Release time:2023-02-08      Number of clicks:159

Exposed in humid air, it can be hydrolyzed into phosphite and hydrogen chloride, and the chemical equation is PCl3+2H2O = HPO2+3HCl, which further generates complexic acid H3PCl6, which occurs white smoke and metamorphism. Storage must be sealed. When ethanol and water hydrolyze, oxygen can produce phosphorus oxychloride.


Phosphorus trichloride is a clear and colorless smoky liquid with a relative density of 1.574 g/cm ^ 3 (21℃), melting point -112℃, boiling point 75.5 ℃, vapor pressure 13.33 kPa (21℃), soluble in ether, benzene, chloroform, carbon disulfide and carbon tetrachloride. Exposed in the air can hygroscopic hydrolysis, into phosphite and hydrogen chloride, white smoke and metamorphism. Interacting with oxygen to form phosphorus trichloride, interacting with chlorine to form phosphorus pentachloride, which ignites in contact with organic matter. Flammable. Easy to irritate mucous membranes, corrosive, poisonous
