Information on molecular formula: Cl2

Character: yellow-green transparent liquid. Freezing point -100.98 ℃. Boiling point -34.6 ℃.
Into a gas at atmospheric pressure gasification. There are asphyxiating chlorine smell. A strong irritant and corrosive. Although spontaneous combustion, but combustion in the sunlight mixed with other flammable gases of combustion and explosion occurred. Easy with the majority of elements or compounds react. Highly toxic. Strong oxidizer.
Chlorine gas industry will be under the low temperature in the pressurized liquefied, a total of three methods: high-pressure method, chlorine pressure 1.4 ~ 1.6MPa (gauge pressure) liquefaction temperature of 30 ℃ ~ 50 ℃. Medium Voltage Law: chlorine pressure 0.2 ~ 0.4MPa (gauge pressure). Low-voltage law: chlorine pressure of about 0.15MPa (gauge pressure), liquid temperature of about -30 ℃
For the textile, paper bleaching. Metallurgical industry for the production of metallic titanium and magnesium. System is also used in pesticides, detergents, plastics, rubber, medicine and other chlorine-containing compounds. Also used in water purification and disinfection.
