Bromine was not produced in large quantities until 1858, when the discovery of salt deposits in Stassfurt enabled its production as a by-product of potash. Other sources claim that the French chemist and physicist Joseph-Louis Gay-Lussac suggested the name brôme for the characteristic smell of the vapors. The name brôme (bromine) derives from the Greek βρῶμος ( brômos, 'stench'). In his publication, Balard stated that he changed the name from muride to brôme on the proposal of M. Īfter the French chemists Louis Nicolas Vauquelin, Louis Jacques Thénard, and Joseph-Louis Gay-Lussac approved the experiments of the young pharmacist Balard, the results were presented at a lecture of the Académie des Sciences and published in Annales de Chimie et Physique. The properties of the resulting substance were intermediate between those of chlorine and iodine thus he tried to prove that the substance was iodine monochloride (ICl), but after failing to do so he was sure that he had found a new element and named it muride, derived from the Latin word muria ('brine'). Balard distilled the bromine from a solution of seaweed ash saturated with chlorine. The seaweed was used to produce iodine, but also contained bromine. īalard found bromine chemicals in the ash of seaweed from the salt marshes of Montpellier. The publication of the results was delayed and Balard published his results first. With this liquid as a sample of his work he applied for a position in the laboratory of Leopold Gmelin in Heidelberg.

After evaporation of the ether, a brown liquid remained. Löwig used a solution of the mineral salt saturated with chlorine and extracted the bromine with diethyl ether. Löwig isolated bromine from a mineral water spring from his hometown Bad Kreuznach in 1825. History Antoine Balard, one of the discoverers of bromineīromine was discovered independently by two chemists, Carl Jacob Löwig and Antoine Balard, in 18, respectively. They retain niche uses as antiepileptics. As a pharmaceutical, the simple bromide ion (Br −) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter-acting drugs. The role of biological organobromine compounds in sea life such as algae has been known for much longer. However, a clear biological role for bromide ions and hypobromous acid has recently been elucidated, and it now appears that bromine is an essential trace element in humans. Large amounts of bromide salts are toxic from the action of soluble bromide ions, causing bromism. Bromine compounds are still used in well drilling fluids, in photographic film, and as an intermediate in the manufacture of organic chemicals. As a result, many organobromine compounds-such as the pesticide methyl bromide-are no longer used.

The same property causes ultraviolet sunlight to dissociate volatile organobromine compounds in the atmosphere to yield free bromine atoms, causing ozone depletion. This effect makes organobromine compounds useful as fire retardants, and more than half the bromine produced worldwide each year is put to this purpose. At high temperatures, organobromine compounds readily dissociate to yield free bromine atoms, a process that stops free radical chemical chain reactions. The mass of bromine in the oceans is about one three-hundredth that of chlorine.Īt standard conditions for temperature and pressure it is a liquid the only other element that is liquid under these conditions is mercury. Commercially the element is easily extracted from brine evaporation ponds, mostly in the United States and Israel. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br −) has caused its accumulation in the oceans. Instead, it can be isolated from colourless soluble crystalline mineral halide salts analogous to table salt, a property it shares with the other halogens. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος (bromos) meaning 'stench', referring to its sharp and pungent smell.Įlemental bromine is very reactive and thus does not occur as a free element in nature. Its properties are intermediate between those of chlorine and iodine. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Bromine is a chemical element with the symbol Br and atomic number 35.
