Zinc dichloride fume

Synonyms/Trade Names Zinc dichloride fume... 

ZINC DICHLORIDE (7646-85-7) ZnCij Noncombustible solid. Reacts with water, forming a medium-strong acidic solution (pH about 4) zinc oxychloride may be formed with large amoimts of water. V iolent reaction with strong bases, amines, amides, and inorganic hydroxides potassium. Attacks metals as fume or in the presence of moisture. Thermal deconq)osition forms toxic zinc oxides and hydrogen chloride fumes. 

General caution and safety. The metal alkyls trimethylaluminum, trimethylgallium, trimethylindium, triethylindium, dimethylzinc, and diethyl-zinc all spontaneously inflame in air (pyrophoric) and are violently reactive toward water and carbon dioxide. Dimethylcadmium fumes upon exposure to air but does not inflame, and decomposes, sluggishly, in water. As with cadmium dichloride, and in common with all cadmium compounds, dimethylcadmium is extremely toxic. A dry powder extinguisher, sand bucket, and fire blanket should be at hand at all times. 

DOT CLASSIFICATION 5.1 Label Oxidizer SAFETY PROFILE Explosive reaction when heated with carbon, 2-aminophenol + tetrahydrofuran (at 65°C). Forms a friction-sensitive explosive mixture with hydrocarbons. Violent reaction with diselenium dichloride, ethanol, potassium-sodium alloy. May ignite on contact with organic compounds. Incandescent reaction with metals (e.g., arsenic, antimony, copper, potassium, tin, and zinc). When heated to decomposition it emits toxic fumes of K2O. See also PEROXIDES. 

ALBUS (10124-48-8) Reacts violently with halogens barium, chlorine, fluorine, and metal salts of amines. Contact with acids or acid fumes causes decomposition, producing hydrogen chloride fumes. Incompatible with organic anhydrides, acrylates, alcohols, aldehydes, alky-lene oxides, substituted allyls, cresols, caprolactam solution, epichlorohydrin, ethylene dichloride, glycols, isocyanates, ketones, maleic anhydride, nitrates, nitromethane, phenols, vinyl acetate. May corrode aluminum, copper, zinc, and some stainless steel in the presence of moisture.
