The Element Bromine

As the only nonmetallic element in normal room temperature liquid, bromine was produced by a young chemical student Carl Löwig in the summer before the first year of the University of Heidelberg. When he showed his red, smelly liquid to his professor Leopold Gmelin, Gmelin noticed that it was an unknown substance and recommended Löwig to make it more so that they can study in detail. Unfortunately, Löwig's work was postponed due to winter trials and vacations, another chemist Antoine-Jérôme Balard was able to publish a paper that explained the new elements in 1826. Ballard was thought to be this discovery and was named after the Greek word for malodor, bromine. Today, bromine is obtained mainly by treating salt water of wells of Michigan and Arkansas with chlorine.

Bromine element is a harmful substance. Adhering to the skin may cause severe burns, which may irritate the eyes, nose and throat. Most of the bromine produced in the United States is used for the production of ethylene dibromide (C 2 H 4 Br 2) which is added to lead gasoline and prevents lead compounds from accumulating in the engine . Due to the suspension of leaded petrol for unleaded gasoline, the demand for bromine has decreased greatly. Silver bromide (AgBr) is a chemical substance used in photography, and currently occupies the maximum amount of bromine. Other bromine compounds are used in some compounds used to purify fumigants, flame retardants and water. Tyrian purple, an expensive purple dye known to the ancient civilization, is produced from organic bromine compounds secreted by Murasakii keikai called Murex.

Elemental bromine is toxic and may cause chemical burns to human flesh. Inhalation of bromine gas causes similar respiratory irritation, causing coughing, suffocation and shortness of breath, which can lead to death if inhaled. Chronic exposure can lead to frequent bronchial infections and general deterioration of health status. As a powerful oxidizing agent, bromine is not compatible with most organic and inorganic compounds. Care is required when transporting bromine; it is usually carried by a steel tank with lead and is supported by a solid metal frame. The Occupational Safety and Health Administration (OSHA) has designated the permissible exposure limit (PEL) for bromine as a time weighted average (TWA) of 0.1 ppm. The National Institute for Occupational Safety and Health (NIOSH) set the recommended exposure limit (REL) to 0.1 A TWA and for a short period to 0.3 ppm. Bromine (IDLH) harmful to life and health is exposed to 3 ppm

The elemental bromine is very active and therefore essentially free, but as well as salt, it is present in a colorless, soluble crystalline inorganic halide salt. It is very rare in the Earth's crust, but the high solubility of bromide (Br -) leads to its accumulation in the ocean. Commercially, this element is easily extracted mainly from the salt fields of America, Israel, China. The mass of bromine in the sea is about three-thirds of chlorine. At high temperatures, organic bromine compounds readily dissociate and generate free bromine atoms. This is the process of inhibiting the chemical chain reaction of free radicals. This effect makes the organic bromine compound useful as a flame retardant and is used for this purpose in more than half of bromine produced worldwide every year. Due to the same characteristics, ultraviolet rays dissociate volatile organic bromine compounds in the atmosphere, generate free bromine atoms, and cause ozone depletion.
