Lithium bromide

Lithium bromide (CAS 7550-35-8), commonly abbreviated as LiBr, is an inorganic salt used across industrial refrigeration, pharmaceutical manufacturing, and life sciences.

Where is Lithium bromide used?

• Industrial refrigeration: absorption refrigerant and desiccant in gas drying systems
• Commercial HVAC and industrial cooling: absorbent fluid in absorption chiller systems
• Chemical synthesis: reagent whose strong affinity for water vapor drives the refrigeration cycle without mechanical compression
• Pharmaceutical manufacturing: reagent in synthesis and buffering agent in select formulations requiring controlled ionic conditions
• Biotechnology and life sciences: solutions precipitate and purify RNA
• Water treatment: biocide and pH-regulation contexts where lithium-based chemistry is specified
• Used in organic synthesis to facilitate carbon-carbon bond formation and catalyze the creation of cyclic compounds.
• Converts alcohols into alkyl bromides.
• An essential reagent in aldol condensations.
• High-purity grades serve as standard reference material or auxiliary component in certain analytical tests.
• In lithium bromide refrigerators, lithium chromate is a common corrosion inhibitor.

Formulation notes

• Aqueous solutions are corrosive to metals; use with corrosion inhibitors is recommended.
• Releases heat when mixed with water.

Typical specification

• Available in an anhydrous form.
• Hydrate offered in a Suprapur grade with a purity of 99.95%.

Regulatory status

• Carries hazard statement H302 (harmful if swallowed).
• Waste directive 2008/98/EC must be observed for disposal.

Storage, packaging and handling

• When working with lithium bromide, moisture control must be ensured and containers must always be kept tightly closed.
• Each drum contains a net content of 30 kg, 300 kg, or 1500 kg, and can be packed according to customer specifications.

Frequently asked questions about Lithium bromide

What role does octanol play in lithium bromide solution?

Octanol is widely used as the surfactant in lithium bromide solution to improve the absorption effect of the absorber and the condensation effect of the condenser.
