Product details

Product name:Bromine
Molecular formula:Br2
Appearance:It is the only non-metallic substance in liquid form at room temperature, appearing as a dark reddish brown liquid.
Property:Melting point -7.2 ℃ Boiling point 58.78 ℃ Relative density 3.119 (20 ℃).
Slightly soluble in water, with a solubility of 3.58g/100ml of water (20 ℃); Easily soluble in ethanol, ether, chloroform, carbon tetrachloride, kerosene, Carbon disulfide and other organic solvents; It is also soluble in hydrochloric acid, Hydrobromic acid and bromine compound solutions. 
It is volatile and has a suffocating odor. Highly toxic, burns the skin, severely irritates the mucous membranes and respiratory tract. Slightly soluble in water, easily soluble in organic solvents. The chemical activity is slightly lower than that of chlorine. Can combine with most metals and non-metals. Strong oxidant, bromine mainly exists in seawater as alkali metal bromide. It can be extracted from bromide in seawater.

Main use:Bromine, also known as industrial bromine, is an important chemical raw material widely used in industries such as flame retardants, fire extinguishing agents, refrigerants, photosensitive materials, pharmaceuticals, pesticides, and petrochemicals. It is widely used in the petroleum industry to produce dibromoethylene, which is used as an antiknock agent for petroleum fuels. Although a small amount is added, the performance of gasoline can be greatly improved. Bromine is used in the pharmaceutical industry to produce sedatives such as Sodium bromide, Potassium bromide, Ammonium bromide, Calcium bromide, and mercuric solutions, as well as hormone intermediates for manufacturing antibiotics such as Chloramphenicol, Chlortetracycline, and synmycin, and vitamin A. In the plastic industry, the development of bromine series flame retardants has significantly improved the fire resistance of plastic products. In the fuel industry, it is used to manufacture eosin, tetrabromo indigo, etc. Used in the production of fumigants, insecticides, and plant growth hormones in pesticides. In addition, bromine can also produce various inorganic chemical products such as Bromous acid, Potassium bromate, Lithium bromide, Hydrobromic acid, etc.
