Carl Jacob Lowig, a German chemist born on March 17, 1803 – died on March 27, 1890. Lowig was the discoverer of bromine periodic table element.


Facts about bromine

Both eminent scientist Antoine Balard and Justus von Liebig discovered bromine. Bromine is the only liquid nonmetallic element. It is a member of the halogen group. It is a heavy, volatile, mobile, dangerous reddish-brown liquid.


Bromine atoms may also react directly with other radicals to help terminate the free radical chain-reactions that characterize combustion.


Bromine is available commercially so it is not normally necessary to make it in the laboratory. Bromine also occurs in seawater as the sodium salt but in much smaller quantities than chloride. It is recovered commercially through the treatment of seawater with chlorine gas and flushing through with air.


Bromine is used in industry to make organobromo compounds. A major one was dibromoethane an agent for leaded gasoline, before they were largely phased out due to environmental considerations. Other organ bromines are used as insecticides, in fire extinguishers and to make pharmaceuticals.


Bromine is used in making fumigants, dyes, flame proofing agents, water purification compounds, sanitizes, medicinals, agents for photography and in brominates vegetable oil, used as emulsifier in many citrus-flavored soft drinks. Bromine is also used in the production of brominated vegetable oil, which is used as an emulsifier in many citrus-flavored soft drinks


Bromine has no essential function in mammals, though it is preferentially used over chlorine by one antiparasitic enzyme in the human immune system.


Bromine may be economically recovered from bromide-rich brine wells and from the Dead Sea waters. Bromine will also oxidize metals and metalloids to the corresponding bromides.


Anhydrous bromine is less reactive toward many metals than hydrated bromine, however. Dry bromine reacts vigorously with aluminum, titanium, mercury as well as alkaline earths and alkali metals.


Bromine vapor is used as the second step in sensitizing daguerreotype plates to be developed under mercury vapor. Bromine acts as an accelerator to the light sensitivity of the previously iodized plate.


Bromine is also used to reduce mercury pollution from coal-fired power plants. Bromine can also be artificially substituted for the methyl substituent in the nitrogenous base thymine of DNA, creating the base analog 5-bromouracil.
