When bromine reacts with a concentrated, heated solution of sodium carbonate, it produces sodium bromate, sodium bromide, and carbon dioxide as the products[3]. 3Br2+ 3Na2CO3→ 5NaBr + NaBrO3+ 3CO2 Sodium bromate is formed through electrolytic oxidation of sodium bromide in which stainless stee...
It is an associative thickener that forms a reversible three-dimensional supramolecular network in solution through intra- and intermolecular associations of the hydrophobic groups. Uses 1. HydroxyEthyl Cellulose and sodium ascorbate disperse in the organic solvent, and by spray drying, the encapsulated ...

By using abundant cellulose in the natural world as the raw material, all 6-site hydroxyl groups of the cellulose 尾-1,4-polyglucose is oxidized into carboxyl groups to form glucuronic acid under the action of a sodium bromide (NaBr)-2,2,6,6-tetramethyl piperidine oxide (TEMPO)-sodium ...
hydrogen-bonding to gener- ate counteranions as nucleophiles or bases for halogen- exchange reactions of octyl bromide (11a) with sodium iodide (NaI) or elimination reactions of 2-bromoethyl- (12a) and 2-iodoethylbenzenes (12b) to styrene (13) in the presence of potassium hydroxide (KOH). ...
Bromine has other uses, as in making variousdyesand the compoundstetrabromoethane (C2H2Br4) andbromoform (CHBr3), which are used as liquids in gauges because of their highspecific gravity. Until the development ofbarbituratesin the early 20th century, bromides ofpotassium,sodium,calcium,strontium...
