Safety Profile
Moderately toxic by inhalation. A skin, eye, and mucous membrane irritant. Will react with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits toxic fumes of F− and Cl−.
Specification
Ethene, dichlorodifluoro- (CAS No.27156-03-2) is a liquid material, which may cause illness from inhalation. When heated to high temperatures Ethene, dichlorodifluoro- may decompose and emit toxic fumes. When in contact with water or steam Ethene, dichlorodifluoro- may produce additional fumes that can cause illness from inhalation. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Ethene, dichlorodifluoro- is a liquid Ethene, dichlorodifluoro- can easily penetrate the soil and contaminate groundwater and nearby streams.
Ethene, dichlorodifluoro- (CAS No.27156-03-2), it also can be called Dichlorodifluoroethylene ; (E)-1,2-Dichloro-1,2-difluoroethene ; Ethylene, 1,2-dichloro-1,2-difluoro- .
