Lithium Bromide

Lithium Bromide (LiBr), a hygroscopic compound composed of lithium and bromine, is widely utilized in industrial and chemical applications due to its unique physicochemical properties. It is synthesized via reactions such as treating lithium carbonate with hydrobromic acid or reacting lithium hydroxide with bromine, yielding crystalline hydrates distinct from other alkali metal bromides.   LiBr exhibits exceptional solubility in water, alcohol, and ether, with concentrated aqueous solutions displaying low water vapor pressures. This property, combined with its high hygroscopicity, makes it an efficient desiccant and liquid sorbent, particularly in absorption refrigeration and air-conditioning systems. Additionally, its ability to dissolve polar organic compounds like cellulose expands its utility in specialized chemical processes, including catalytic dehydrohalogenation for olefin synthesis.   In water treatment and crystal growth applications, LiBr’s solubility and ultra-high purity forms (submicron/nanopowders) are advantageous. The bromide ion can be detected in aqueous solutions using carbon disulfide and chlorine. However, handling requires caution: LiBr generates significant heat upon dissolution (due to negative enthalpy of solution) and poses hazards as a mildly corrosive and psychoactive substance.   UrbanMines supplies LiBr in various grades (Mil Spec, ACS, Pharmaceutical, etc.), packaging options, and purities, adhering to ASTM, USP, and EP/BP standards. Technical support, safety data (MSDS), and unit conversion tools are provided to ensure safe and optimized application across industries.
