Ammonium Chloride

Description

Properties: 1) Colorless cubic crystal or white crystalline substance with a salted and light bitter taste 2) The specific gravity is 1.**7 3) It begins to vaporize without melting at **0°C and boil at **0°C 4) It is highly soluble in water, readily forming a slightly acidic solution whose acidity will be stronger 5) It is also soluble in liquid ammonia and slightly soluble in alcohol but not soluble in acetone and aether 6) It observably volatilizes when heated at **0°C and dissociates into ammonia and HC1, which combine into NH4C1 again when cooling in the form of white foggy substance containing extremely small granules of NH4C1 7) This substance can not precipitate and become extremely insoluble in water 8) It has a weak hygroscopicity but can cake due to water absorption in wet or rainy days 9) It corrodes black metals and other non-ferrous metals, especially copper, but it does not corrode pig iron Usages: 1) Principal use is in mining, tannery and fertilizer 2) It is also extensively employed as a constituent of dyeing, electro-bath and soldering fluxes 3) Also it is used in galvanizing, tinning, medicine, candle making, adhesive, chromizing and precision casting and producing dry and storage batteries and other ammonium saltIndustry grade: NH4C1: *9.5, *9.0% min. Storage: 1) Store in a cool, dry, and ventilated house away from moisture 2) Avoid handling or transporting together with acidic or alkaline substances 3) Prevent the material from rain and insolation 4) Load and unload carefully and protect from package damage 5) In the event of a fire, use water, soil or carbon dioxide fire extinguishing media.
