Chlorine trifluoride

Human poison by inhalation. An eye irritant. See also FLUORIDES, CHLORINE, and FLUORINE. Spontaneously flammable. A powerful oxidant which may react violently with oxidizable materials. A rocket propellant.Explosive reaction with water, bis(trifluoro methyl)sulfide or -disulfide, polychlorotrifluoroethylene, trifluoromethanesulfenyl chloride, and other hydrogen- containing materials (e.g., ammonia, coal gas, hydrogen, hydrogen sulfide, methane, acetic acid, benzene, ether, cotton, paper, wood). Forms shock-sensitive explosive mixtures with highly chlorinated compounds (e.g., carbon tetrachloride), nitroaryl compounds (e.g., trinitrotoluene, hexanitrobiphenyl, hexanitrodiphenyl amine, hexanitro diphenyl sulfide, hexanitrodiphenyl ether). Reaction with ammonium fluoride or ammonium hydrogen fluoride forms explosive gaseous products.Ignition on contact with boron-containing materials, iodine, finely divided refractory materials (e.g., asbestos, glass wool, sand, tungsten carbide), fluorinated polymers (with flowing trifluoride).Violent reaction with acids (e.g., nitric or sulfuric), chromium trioxide, ruthenium, selenium tetrafluoride (above 106°C), metals, metal oxides, metal salts, nonmetals, nonmetal salts, organic matter, glass wool, acetic acid, Al, Sb, As, Cu, Ir, Fe, Pb, Mg, Mo, Os, P, K, Rh, Se, Si, Ag, Na, S, Te, Sn, W, Zn, oxides, CO, graphite, HgI2, HNO3, K2CO3, KI, rubber, AgN3, AgNO3, NaOH, V2P5, WO3. Incompatible with fuels, nitro compounds. When heated to decomposition or in reaction with water or steam it emits toxic fumes of F− and Cl−.
