Lithium Bromide
LiBr | CAS: 7550-35-8 | HS: 28275900
Product Description
Lithium Bromide is the critical working fluid in absorption refrigeration and air-conditioning systems, where a concentrated LiBr-water solution functions as the absorbent in the refrigeration cycle — enabling large-scale, electrically efficient chilling of commercial buildings, industrial processes, and district cooling networks. It is also used as a powerful industrial desiccant and as a reagent in pharmaceutical and organic synthesis. MITCHEM supplies consistent purity with controlled heavy metal limits and full CoA documentation for HVAC equipment manufacturers and chemical processors.
Applications by Industry
LiBr solution is the absorbent in LiBr-water absorption chillers used for large-scale commercial cooling; systems are driven by waste heat or gas rather than electrical compressors, offering significant energy savings.
Concentrated LiBr solution is used in liquid desiccant air-handling systems for pharmaceutical manufacturing, food processing, and humidity-controlled storage facilities.
Used as a reagent for halogen exchange reactions (Finkelstein-type), as a solubility enhancer for certain polymers, and as a source of bromide in specialty synthesis.
Applied in fibre dissolution systems for producing regenerated cellulose fibres, where LiBr-ZnCl₂ or LiBr-DMSO solvent systems dissolve cellulose for wet spinning.
