Physicochemical propertiesIt's a kind of transparently clear fuming liquid with relative density of 1.574, melting point of -112°C and boiling point of 75.5°C. It can be dissovled in ether, ben-zene, tetrachoride, carbon disulfide. Phosphorous acid and hydrogen chloride can be generated when exposed to moist air, then it degenerates and gives off white smoke.Violent decomposition happens when exposed to water which can give off hydrogen chloride gas.PCL3 can be generated when reacts with oxygen and chlorine,respectively. Fire is easily taken when it contacts with organic compound .And it's combustible, irritative,corrosive and toxic. 7. Uses:Mostly be used in making trichlorphon, acephatemet, orthene, phosphorus oxychloride, orthophosphorous acid, triphenyl phosphate and triphenolyl phosphate, also be used in making intermediate of S.D and S.N.D in medicine industry, and used as condensating agent and catalyst in dye industry. 8. Package: in dry clean plastic drum or ISO tank.UN No:1809. Class 6.1.It’s inorganic acidic corrosives and transport regulations for dangerous goods should be followed.
