INTRODUCTION
Lithium bromide (LiBr) is a white, hygroscopic solid. The hygroscopic nature makes it a versatile chemical that can be put to various end uses. It is usually sold in anhydrous form or in aqueous solutions of varying concentrations.
Manufacture
The salt is produced by reaction between lithium carbonate and hydrobromic acid. Alternatively, it is also produced by bromination of lithium hydroxide.

APPLICATIONS
Medicinal Uses
LiBr acts as sedative and is used in treatment of bipolar disorders. It is also a medical humectant.
Air Conditioning
The bromide finds its major application in some air conditioning systems, whereby its 55-60% aqueous solution is used as desiccant (phenomenon of absorption chilling).
Chemical Processes
The salt is further applied in various processes such as:
| Absorption of water vapors (vapor absorption media) |
| Catalyst in dehydrogenation reactions |
| Low temperature heat exchange processes |
| Carbonyl compound condensations with active methylene compounds |
| Some alkylation reactions |
| Inexpensive catalyst in epoxide ring opening using amines |
| Deprotonation and dehydration of organic molecules possessing acidic protons |
| Purification of steroids |
Others
Reconstitution of brines, electrolyte component in Li batteries, and welding flux are some of the feeble uses of LiBr.

N-Acetyl-L-aspartic acid, abbreviated as NAA, is second most abundant molecule in nervous systems after amino acid glutamate. It is synthesized in brain from aspartic acid and acetyl co-enzyme A. It also acts as nutrient.
Pivaloyl chloride is a colorless to light yellow liquid with a pungent mustard-like odor. It hydrolyses in the presence of water.
1,3-Dimethyl-2-imidazolidinone, popular as DMI solvent, is a high boiling aprotic polar molecule. Apart from being a common solvent in derivative GC, it finds applications in diverse industrial verticals.
Iron, Electrolytic, occurs as an amorphous, lusterless, gray-black powder. It is elemental iron obtained by electrode deposition. It is stable in dry air.
Hot melt polyamide adhesives are 100% non-volatile, thermoplastic adhesive resins. These are heat-resistance hot melt adhesive, suitable for bonding materials hard to bond together.
Boron citrate, usually called “boron”, is a micronutrient with diverse and vitally important roles in metabolism that render it necessary for plant, animal, and human health, and, possibly, as recent research suggests, for the evolution of life on Earth.
Ethone, chemically 1-(p-methoxyphenyl)-1-penten-3-one, is a flavor and fragrance ingredient. Available in white to yellow crystalline powder form, it bears sweet and anisolic taste.
Mercuric ammonium chloride, also called white precipitate, is a heavy white odourless amorphous compound used in external treatment of skin diseases and to destroy lice.
Stannic chloride pentahydrate is a tin source compatible with chlorides. Biologically, it induces a slight inhibition in the catalytic activity of the enzyme horse liver alcohol dehydrogenase (HLADH).
