Specification: IS: 2142-1992 (reaffirmed in 1997).Description: A dark reddish-brown fuming liquid with a highly irritating odour.
Properties and storage: Liquid bromine is a dark, reddish-brown, fuming, volatile liquid with a suffocating odour. Bromine attacks all metals and organic tissues. It vaporises at room temperature.
One litre of bromine weighs about 3.1 kg. One ml of bromine dissolves in about 30 ml of water. It is freely soluble in alcohol, chloroform, ether, carbon disulphide, carbon tetrachloride and concentrated hydrochloric acid. Liquid bromine should be stored in well-stoppered containers.
Normally, bromine is stored in amber-coloured glass containers or glass-lined steel tanks, but dry bromine can be stored in well-designed lead-lined or monel drums.
Uses: Bromine is used primarily in the manufacture of organic and inorganic bromides. It is an important reagent in the preparation of organic compounds involving a bromination step. It is also used in water treatment, shrink-proofing wool, as an intermediate for fumigants, as fire-extinguisher fluid and military poison gas.
Safety precautions: While handling bromine, always keep ammonia water within reach.
Packing: 3- and 3.5-kg glass bottles.
