1,1-Dibromoethane is a clear, slightly brown, flammable chemical compound. [3] It is classified as the organobromine compound, and has the chemical formula C 2 H 4 Br 2 [4] and it is a position isomer of 1,2-dibromoethane. It is commonly seen in industrial chemistry, where it is used as a fuel additive. [5]

Dibromoethane can refer to either of two isomeric organobromides with the molecular formula C 2 H 4 Br 2: 1,1-Dibromoethane (ethylidene dibromide) 1,2-Dibromoethane (ethylene dibromide)
1,2-Dibromoethane has wider applications in the preparation of other organic compounds including those carrying modified diazocine rings [9] and vinyl bromide that is a precursor to some fire retardants. [4] In organic synthesis, 1,2-dibromoethane is used to brominate carbanions and to activate magnesium for certain Grignard reagents.
Dibromomethane is used as a solvent, gauge fluid, and in organic synthesis (often as 1 H-NMR internal standard). [3] It conviently converts polyols (such as catechols ) to their methylenedioxy derivatives, and bromomethylenates enolates .
Iodine, methyl iodide, and 1,2-dibromoethane are common activating agents. The use of 1,2-dibromoethane is advantageous as its action can be monitored by the observation of bubbles of ethylene. Furthermore, the side-products are innocuous: Mg + BrC 2 H 4 Br → C 2 H 4 + MgBr 2

The binder is a combination of silica sol and water glass. The organic fraction is limited to 5 mass percent similar to dispersion silicate paint allowing for chemical setting and retaining of the silicate specific advantages. The sol silicate paint allows use on non-mineral plaster. [4] For these the bonding occurs chemically and physically.
