Safety Profile
The liquid at 2 °C is an unstable spark- and touch-sensitive explosive. The gas may explode when heated above 42 °C. A powerful oxidizing agent. Explodes on contact with alcohols, ammonia, antimony, antimony sulfide, arsenic, barium sulfide, calcium phosphide, carbon, carbon disulfide vapor, charcoal, cork, dicyanogen, ethers, hydrogen sulfide, mercury sulfide, nitrogen oxide, paper, phosphine, phosphorus, potassium, rubber, sulfur, tin sulfide, turpentine, and other oxidizable materials. Self-explodes. Incompatible with carbon, dicyanogen, diphenylmercury, nitrogen oxide, oxidizable materials, and potassium. Explosive reaction when heated above 50 °C with many hydrocarbons (e.g., butadiene, ethane, ethylene, methane, propane).
Specification
Dichlorine oxide (CAS NO.7791-21-1) is also named as Chlorine monoxide ; Chlorine oxide (Cl2O) . Dichlorine oxide (CAS NO.7791-21-1) is red-yellow gas. It is very reactive and unstable. So it unusually stored as hydrate in frozen form. Dichlorine oxide can form chlorine and oxygen gases when decomposes in water. It can dissolve in alkalis, forming a mixture of chlorite and chlorate. It also explodes when heated or by reaction with organic materials, including: carbon, carbon disulfide, ethers, hydrocarbons, dicyanogen, any readily oxidizable materials (ammonia, potassium, arsenic, antimony, sulfur, mercury sulfide, calcium phosphide, phosphine, phosphorus, hydrogen sulfide, antimony sulfide, barium sulfide, mercury sulfide, and tin sulfide). Concentration of gas should be limited to less than 10% to reduce explosion hazard. Alcohols are oxidized explosively.
