| Regulatorische Informationen | The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.) |
| Reaktive Gruppe | Oxidizing Agents, Strong |
| Reactivity Alerts | Explosive |
| Reactivity Profile | 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). Dissolves in alkalis, forming a mixture of chlorite and chlorate. Concentration of gas should be limited to less than 10% to reduce explosion hazard. Alcohols are oxidized explosively. |
