Colorless, pungent odor of smoking liquid, melting point 1.25C, boiling point 105.8C, molecular weight 153.33. Water and ethanol are easy to decompose wꦇell release a lot of heat and hydrochloric acid gas, eye irritation. Highꦛly corrosive.

Product use

Electron-grade phosphorus trioxide is an dopant made of PN junction in integrated circuit (IC) production and fine processing of polysilicon solar cells, a🦩nd is a diffusion source of pentavalent element phosphorus (P). Electron-grade phosphorus oxychloride is also used in optical fiber processing and pharmaceutical synthesis.

Toxicity and protection

Phos🌄phorus oxychloride volatile gas toxic, stimulating and corrosion resistance, can stimulate the mucous membrane, make eye Fu, dry cough, severe breathing difficulties, b🐎ronchitis, occurring after cardiac insufficiency, severe anemia, hepatomegaly, urine protein, lung boundary. Splashes of 1 drop into the conjunctival sac of the eye will cause necrosis and complete loss of vision. The maximum permissible concentration is 0.051-ng/m3. Operators should wear labor protection equipment, the equipment for producing phosphorus oxychloride should be closed, and filter gas masks should be worn during work to carefully protect the skin and eyes.

Packaging and transport

The containers are mainly packed with high purity quartz source bottles, with specifications of 500rnI/ bottle, 1000ml/ bottle and 1500ml/ bottle. The containers are covered with opaque plastic film and thick PVC plastic baไgs. In addition, according to customer requirements, different specifications and special cylinder packaging. The conta♒iners are packed in PE plastic boxes with built-in sponge cushions, and the marks of "drugs" and "corrosive substances" should be clearly marked on the packages. Grade inorganic acid corrosion articles, dangerous code: GB8.1 class 81040. Electron-grade trioxion should be stored in a cool, ventilated, dry warehouse, the container must be sealed, away from heat and fire. Not with inflammable, deliquescent goods storage mixed transport. It shall be protected from rain and sun during transportation, handled and put gently during loading and unloading, and protected from impact of E and packaging damage. In case of fire, dry yellow sand, dry powder extinguisher or carbon dioxide extinguisher can be used, but not with water.
