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.

What is Lithium Bromide (LiBr) used for?
Lithium Bromide (LiBr) serves diverse roles across industrial, chemical, and pharmaceutical sectors. A 50–60% aqueous LiBr solution is extensively employed in air-conditioning and absorption refrigeration systems, where its hygroscopic nature enables efficient moisture absorption and heat transfer, facilitating energy-efficient cooling. Similarly, LiBr acts as a coolant in industrial absorption-based air-cooling systems, leveraging its thermodynamic properties for temperature regulation.
In organic synthesis, solid LiBr is a versatile reagent. It enhances catalytic processes such as oxidation and hydroformylation, aids in deprotonation and dehydration of acidic organic compounds, and supports purification of complex molecules like steroids and prostaglandins. Its solubility in polar solvents further enables applications in specialized chemical syntheses.
Within the pharmaceutical industry, LiBr functions as a drying agent and participates in manufacturing processes. Historically, it was utilized as a sedative and treatment for bipolar disorder and epilepsy, though its medical use declined post-1940s due to safety concerns and the advent of alternatives.
LiBr’s solubility in alcohol and ether also makes it valuable in photographic technology, particularly in formulating collodion dry plate emulsions. Additionally, high-purity LiBr is applied in niche industrial processes, including water treatment and crystal growth, where its stability and ionic properties are advantageous.
Combining versatility with functional efficiency, LiBr remains critical in advanced cooling systems, chemical manufacturing, and specialized industrial applications, underscoring its adaptability across technical fields.
