Electronic grade Phosphorus trichloride
Molecular Formula: POCl3
Molecular weight: 137.34
Physical and Chemical Properties:
Clarify colorless liquid, humid air in the smoke. Relative density 1.574 (21 ℃). Melting point -111.8 ℃. Boiling point 75.5 ℃, vapor pressure 13.33kPa (21 ℃). Toxic. Flammable, contact with organic matter will be on fire, non-combustible in air. Sheng corrosion, easy to stimulate the mucosa. Moist air or water can quickly break down. Soluble in benzene, ethyl ether, carbon disulfide, carbon tetrachloride. Case of ethanol and water can be hydrolyzed into phosphoric acid and hydrogen chloride Asia, the occurrence of white smoke, exposure to moisture in air to hydrolysis, the occurrence of white smoke and metamorphism.
Uses: In the semiconductor industry, phosphorus trichloride can be used as ion implantation. It is the quality of chlorinated organic compounds, agent, catalyst and solvent for phosphorus, phosphide high-purity synthetic intermediates.
Package: Plastic bucket or iron barrel, net weight of each pail is 250kg or 300kg. Tank wagon can be used, too.
