Physicochemical property

Colorless transparent smoky liquid, relative density 1.574, melting point -112°C, boiling point 75.5°C, soluble in ether, benzene, carbon disulfide and carbon tetrachloride. In the moist air, it can be hydrolyzed into phosphite and hydrogen chloride, resulting in white smoke and deterioration. In the presence of water, it will decompose violently and release hydrogen chloride gas, which will react with oxygen to produce phosphorus trichlorooxygen and with chlorine to produce phosphorus pentachloride. It will catch fire in contact with organic matter. Flammable, easy to irritate mucous membranes, corrosive, toxic.

Use：

It is mainly used as raw material of organophosphorus pesticides such as trichlorphon, methamidophos and acephate trichlorophosphorous acid, phosphite, triphenyl phosphate and triphenol phosphate, as well as oryzidine. Pharmaceutical industry for the production of sulfadiazine (S, D), sulfadimethylate (S, M, D). Dye industry is used as a shrinking agent and catalyst for chromatic phenols.

Packing：

Use dry iron drum, 200KG/ drum, or can be transported by tank truck. This product belongs to the first class inorganic acid corrosion products, danger number: 91020. Shipments shall be made in accordance with the dangerous Goods transport regulations.
