Chemical Description

Sodium bromide is a salt that is commonly used as a source of bromide ions in chemical reactions.

Use Description

Sodium bromide, a chemical compound, finds applications in various fields. In the medical industry, it has historically been used as a sedative and anticonvulsant, although its medical use has declined in favor of safer alternatives. In the oil and gas industry, sodium bromide is utilized as a dense brine fluid in drilling fluids, aiding in wellbore stability and preventing blowouts. In the photography sector, it plays a crucial role as a component in silver bromide emulsions used in traditional black-and-white photography. Additionally, sodium bromide is used in some chemical synthesis processes and as a disinfectant in water treatment, particularly in hot tubs and swimming pools. Its ability to control microbial growth in water makes it valuable for maintaining water quality. While its applications have evolved over time, sodium bromide continues to be relevant in these various fields for its unique properties and functions.

Chemical Reactions

Utilized in the electrochemical bromination of enamide derivatives, facilitating the formation of C(sp2)鈭払r bonds.
Applied in the electro-oxidation of sulfides to sulfones, providing a chemo-selective method for sulfoxidation.
Sodium bromide serves as the oxidant in the electro-oxidation process, contributing to environmentally friendly reactions with high efficiency and mild conditions.

Synthesis Reaction

Synthesized by combining sodium (Na) and bromine (Br2), forming sodium bromide (NaBr) through a synthesis reaction.

Surface Activity and Ionic Liquids

Dodecylbenezenesulfonate-based anionic surface active ionic liquids (DBS-ILs) paired with onium cations have been synthesized. DBS-ILs exhibit high surface activity and can form micelles, which can be transformed into vesicles with the addition of sodium bromide (NaBr).
The transition from micelles to vesicles is driven by entropy factors and increased electrostatic interactions between sulfonate headgroups and counterions, along with cation-蟺 or 蟺鈥撓? interactions.
