Where is bromine most commonly found?

seawaterBromine is found naturally in the earth's crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire).

Where is bromine obtained from?

How is bromine produced?

It is produced on a large scale by direct reaction of bromine with excess fluorine at temperatures higher than 150 °C, and on a small scale by the fluorination of potassium bromide at 25 °C. It is a very vigorous fluorinating agent, although chlorine trifluoride is still more violent.

What is the role of bromide in sea life?

The role of biological organobromine compounds in sea life such as algae has been known for much longer. 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.

What are binary bromides?

Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2 ); extreme nuclear instability hampering chemical investigation before decay and transmutation (many of the heaviest elements beyond bismuth ); and having an electronegativity higher than bromine's ( oxygen, nitrogen, fluorine, and chlorine ), so that the resultant binary compounds are formally not bromides but rather oxides, nitrides, fluorides, or chlorides of bromine. (Nonetheless, nitrogen tribromide is named as a bromide as it is analogous to the other nitrogen trihalides.)

How much bromoform is released in the ocean?

The oceans are estimated to release 1–2 million tons of bromoform and 56,000 tons of bromomethane annually. An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced.

What are the two isotopes of bromine?

Bromine has two stable isotopes, 79 Br and 81 Br . These are its only two natural isotopes, with 79 Br making up 51% of natural bromine and 81 Br making up the remaining 49%. Both have nuclear spin 3/2− and thus may be used for nuclear magnetic resonance, although 81 Br is more favourable. The relatively 1:1 distribution of the two isotopes in nature is helpful in identification of bromine containing compounds using mass spectroscopy. Other bromine isotopes are all radioactive, with half-lives too short to occur in nature. Of these, the most important are 80 Br ( t1/2 = 17.7 min), 80m Br ( t1/2 = 4.421 h), and 82 Br ( t1/2 = 35.28 h), which may be produced from the neutron activation of natural bromine. The most stable bromine radioisotope is 77 Br ( t1/2 = 57.04 h). The primary decay mode of isotopes lighter than 79 Br is electron capture to isotopes of selenium; that of isotopes heavier than 81 Br is beta decay to isotopes of krypton; and 80 Br may decay by either mode to stable 80 Se or 80 Kr.

Foci of bronchopneumonia were found in animals that died several days after exposure and there was evidence of functional disturbances in CNS.

How is brine made?

Raw brine is warmed in a heat exchanger and caused to pass successively through two packed towers by gravity flow. In the upper (smaller) tower, it meets a recycle stream of gases from which chlorine and bromine are absorbed. Near the bottom of the lower tower, chlorine and steam are introduced; as they pass upward, the chlorine reacts with bromide in the brine, and a mixture of bromine vapor and chlorine (about 85:15 by weight) with steam is taken off the top. The water and most of the halogens are condensed, the liquid phases enters a gravity separator and the gas goes to the upper tower. From the separator, water containing dissolved halogens is sent to the lower (steaming-out) tower and the heavier bromine layer, containing some chlorine, flows to a fractionating column. The chlorine vapors join the stream to the upper tower while the liquid bromine, about 99 % pure, is drawn off either for direct use in the manufacture of bromine compounds or to be further purified for sale or for more exacting uses.
