Molecular formula : MW : CAS :
nature : PCl3 colorless liquid clarity. If a trace of free phosphorus exists, a yellowish color and turbidity. Density 1.574. -112 ° C melting point. The boiling point of 76 ° C. Soluble benzene, ether, carbon disulfide, carbon tetrachloride, exposed to moist air, which can be hydrolyzed Phosphite and hydrogen chloride, white smoke occurred twisted, must be sealed in storage. Met with ethanol and water decomposition reaction, except oxygen can generate oxygen, phosphorous trichloride, phosphorous acids, Asia phosphate, chloride is also used as agents, catalysts, solvents, etc.. Will from the dry chlorine leads to phosphorus and phosphorus trichloride (reactor can be relaxed) of the mixture, then finely-distillation.
