Lithium bromide is used as a medium for air-conditioning, and a desiccant industrial drying system. It finds use as a sedative and hypnotic. Further it is employed in manufacturing pharmaceuticals, in alkylation processes, and as brazing and welding fluxes. In addition, lithium bromide-water solution is widely used in absorption refrigeration systems, absorption heat pumps and absorption heat transformers. l-Proline lithium bromide monohydrate (LPLBM) is a promising semi-organic nonlinear optical material.
Lithium bromide is prepared industrially by the reaction of either
lithium hydroxide monohydrate or lithium carbonate with hydrobromic acid, which may
be prepared in situ by the reduction of bromine. The solution may be evaporated to yield
anhydrous lithium bromide if desired.
