Bromine (greek "bromos" meaning "stench") is a hard, volatile, corrosive liquid with a pungent odor. Bromine vapors are very toxic upon inhalation. It has a dark-violet color in reflected light and a dark-red in transmitted light. Bromine is a halogen element and has the physical form of a diatomic molecule, Br2; Br4 molecules were discovered in vapours. Molecular bromine is diamagnetic. It is soluble in water (3.58g in 100g of water at 20°C), solubility rises in the presence of chlorides and bromides. It is miscible in most organic solvents. Bromine is highly reactive and is a powerful oxidizing agent. With many of the metals and elements, anhydrous bromine is less reactive than wet bromine; however, dry bromine reacts vigorously with aluminium, titanium, mercury as well as alkaline earth metals and alkaline metals. It is readily reacts with organic compounds. Most typical reactions are additions to multiple bond and substitution of hydrogen atom. Bromine acts with hydrogen to give hydrogen bromide HBr. Its solution is called hydrobromic acid; salts - bromides. Bromine also forms a number of oxygen-containing acids, such as hypobromous acid (HBrO), bromous acid (HBrO2), bromic acid (HBrO3) and perbromic acid HBrO4.


Due to leaching, bromide salts have accumulated in sea water and may be economically recovered from it or lacustrine and underground brines.


Elemental bromine is used:

  • in making a number of inorganic chemistry products such as NaBr, KBr, HBr and other. It also used to produce some reagents for photography;
  • much bromine output were used previously in the production of 1,2-dibromoethane (ethylene dibromide), a lead scavenger used in making petrol antiknock compounds before they were largely phased out due to environmental considerations;
  • to produce organic compounds - fumigants, brominated flame-retardants, water purification compounds, dyes, desinfectants;
  • to make pharmaceuticals;
  • to manufacture herbicides, insecticides and other agricultural chemicals;

  • Manufacturer(s) OJSC Brom
