Uses and applications
What the substance is used for, by industry and function
The active ingredient is no longer contained in any registered products ... "cancelled.".
Soil and grain fumigant, as lead scavenger in anti-knock gasolines.
EDB is a versatile reagent in organic synthesis. Major uses in this category are as an intermediate for pharmaceuticals (tetramisole, theodrenaline), herbicides (diquat dibromide), and dyes (Vat Blue 16), where it provides an ''ethylene bridge'' in the molecular structure. EDB is used as a nonflammable solvent for resins, gums, and waxes. Additionally, EDB can be used as a raw material in the synthesis of chemicals such as vinyl bromide (a precursor of flame-retardants) and styrenic block copolymers.
Ethylene dibromide was used in the past as an additive to leaded gasoline, however, since leaded gasoline is now banned, it is no longer used for this purpose. Ethylene dibromide is currently used in the treatment of felled logs for bark beetles and termites, and control of wax moths in beehives.
Industrial uses: Fuel agents.
Consumer uses: Fuel agents.
Use classes: Volatile organic compounds.

Pharmacology
Ethylene Dibromide is a clear, colorless, volatile liquid brominated hydrocarbon with a mild, sweet, chloroform-like odor that emits corrosive and toxic fumes when heated to decomposition. Ethylene dibromide is used as a chemical intermediate in the synthesis of resins, waxes, gums, dyes and pharmaceuticals and is used to produce vinyl bromide. Exposure to ethylene dibromide severely irritates the skin and causes depression and collapse. Ethylene dibromide affects DNA integrity by alkylation and is reasonably anticipated to be a human carcinogen.
How it is made
Made from ethylene and bromine, also from acetylene and hydrobromic acid.
EDB is manufactured via uncatalyzed, liquid-phase bromination of ethylene. Gaseous ethylene is brought into contact with bromine by various methods, allowing for dissipation of the heat of the reaction.
The commercial manufacturing process is carried out in a glass column reactor consisting of a lower packed section and an unpacked upper section containing a number of superimposed, high-capacity, coil heat exchangers.

Liquid bromine is continuously added above the packed section while a slight excess of ethylene is continuously fed countercurrently from the bottom of the packed section. The exothermic reaction between ethylene and bromine occurs in the liquid phase on the surfaces of the cooling coils, and heat is removed at a rate sufficient to maintain a maximum temperature of 100 °C and the section of the column. Some reaction also occurs in the gas phase above the bromine feed where product is condensed and separated from the vent gas (ethylene, hydrogen bromide, and interact material). As the crude liquid product passes downward through the packed section, it provides a contacting surface for rising ethylene to convert any residual dissolved bromine. Ethylene dibromide is continuously withdrawn from the reactor into a hold-up tank where it is irradiated with ultraviolet light to eliminate minor amounts of unconverted starting materials.
