Packing Group I
Phosphorus Trichloride (CAS: 7719-12-2), is a clear, colorless, fuming, corrosive liquid. It decomposes rapidly in moist air. It mixes with diethyl ether, petrol, chloroform, carbon disulfide and dichloroethane in all ratios: It can be easily destroyed with water, acids and alcohols. Phosphorus trichloride vapours hydrolyse even in humid air. PCl3 is a strong oxidizer and will readily react with many organic compounds.
Phosphorus Trichloride is very poisonous; it causes serious skin burns and can cause death when enters the human body (even in small quantities). The maximum allowable concentration of phosphorus trichloride Vapours in industry is 0.5 mg/m3.
Phosphorus Trichloride is an important intermediate in the production of insecticides, herbicides, and organophosphorus pesticides as well as other chemicals such as phosphoryl chloride, phosphorus pentachloride, thiophosphoryl chloride, and phosphonic acid. It is also used in the production of synthetic surfactants, phosphites, gasoline additives, flame retardants, plasticizers, dyestuffs, silver polish, and producing iridescent metallic deposits, germicides, medicinal products, and other chemicals.
Phosphorus trichloride is used as a chlorinating agent; and as a catalyst.
Phosphorus Trichloride is used to prepare phosphine and other phosphorus compounds.
Phosphorus trichloride is highly toxic; it may cause death or permanent injury. Contact is highly irritating to the skin, eyes, and mucous membranes, and the material is an irritant through oral and inhalation exposure.
Phosphorus Trichloride will react violently with water, producing heat and toxic and corrosive fumes. When heated to decomposition, Phosphorus trichloride emits highly toxic fumes of chlorides and phosphorus oxides. Phosphorus trichloride may ignite other combustible materials. Reacts violently with water. Reacts explosively with acetic acid, aluminum, chromyl chloride, diallylphosphite and allyl alcohol, dimethyl sulfoxide, fluorine, hydroxylamine, iodine monochloride, lead dioxide, nitric acid, nitrous acid, organic matter, potassium, and sodium. Avoid contact with water, steam, or acids. Hazardous polymerization may not occur.
Phosphorus Trichloride is not allowed to be stored and mixed with flammable items, deliquescent and other items. When loading and unloading should be careful to prevent the rupture of the packaging bottle. When there is a fire, dry sand and dry powder can be used to put out the fire, and water cannot be used. Keep away from fire and heat source.
