6 CH 2 BrCl + 3 Br 2 + 2 Al → 6 CH 2 Br 2 + 2 AlCl 3 CH 2 BrCl + HBr → CH 2 Br 2 + HCl. In the laboratory, it is prepared from bromoform using sodium arsenite and sodium hydroxide: [4] CHBr 3 + Na 3 AsO 3 + NaOH → CH 2 Br 2 + Na 3 AsO 4 + NaBr. Another way is to prepare it from diiodomethane and bromine.
EuBr 3 + 1 / 2 H 2 → EuBr 2 + HBr 2 TaBr 4 TaBr 3 + TaBr 5. Most of the bromides of the pre-transition metals (groups 1, 2, and 3, along with the lanthanides and actinides in the +2 and +3 oxidation states) are mostly ionic, while nonmetals tend to form covalent molecular bromides, as do metals in high oxidation states from +3 and above.
This can be seen from the standard electrode potentials of the X 2 /X − couples (F, +2.866 V; Cl, +1.395 V; Br, +1.087 V; I, +0.615 V; At, approximately +0.3 V). Bromination often leads to higher oxidation states than iodination but lower or equal oxidation states to chlorination.
2 NaCN + Br 2 → (CN) 2 + 2 NaBr (CN) 2 + Br 2 → 2 (CN)Br. When refrigerated the material has an extended shelflife. Like some other cyanogen compounds, cyanogen bromide undergoes an exothermic trimerisation to cyanuric bromide ((BrCN) 3). This reaction is catalyzed by traces of bromine, metal salts, acids and bases.
DBDMH (also known as 1,3-Dibromo-5,5-Dimethylhydantoin) is an organic compound derived from the heterocycle called dimethylhydantoin.This white crystalline compound with a slight bromine odor is widely used as a disinfectant used for drinking water purification, recreational water treatment, as a bleaching agent in pulp and paper mills, and for treating industrial/commercial water cooling systems.
