Brief Overview


Lithium Chloride is extremely soluble in polar solvents such as water due to the small size of Li+ ion. LiCl form crystalline hydrates, unlike other alkali metal c hlorides. The anhydrous salt can be regenerated by heating the hydrates. LiCl also absorbs up to four equivalents of ammonia/mol.


Manufacturing Process


There are many ways of manufacturing Lithium Chloride:


Method 1: Lithium chloride may be prepared by reaction of lithium carbonate or lithium hydroxide with hydrochloric acid followed by crystallization:

Li2CO3+ 2HCl → 2LiCl + CO2+ H2O LiOH + HCl → LiCl + H2O

Crystallization above 95°C yields anhydrous salt. Hot solution upon cooling forms crystals of monohydrate, LiCl.H2O.


Method 2: Reaction of lithium ores with chlorides or natural brines.

Chemical Industry:


  • Mainly used to produce lithium metal by electrolysis of a LiCl/KCl which melts at 450 °C (842 °F)


  • Also used as a brazing flux for aluminium in automobile parts.


  • An additive in the Stille reaction in organic synthesis.


Other Applications:


  • Flame colourant to produce dark, red flames


  • Preparation of carbon nanotubes, graphene and lithium niobite


  • Desiccant in dehumidification systems.
