Product Application:

It is used for air conditioning, as a soldering aid, a drying agent, a chemical reagent, and for making fireworks, and also for dry batteries and metallic lithium, etc.

Production Methods and Others:

Evaporating the LiCl aqueous solution yields LiCl·H2O crystals. Above 98℃, the anhydrous salt can be obtained. However, before all the water in the crystals is removed by heating, the product loses some HCl through hydrolysis, making it alkaline. Pure anhydrous LiCl (with a pH of 6-7 in the aqueous solution) needs to be obtained by reducing pressure dehydration and heating with NH4Cl. It can also be prepared by heating in a dry HCl gas flow at 200℃ under an oxygen-free condition or by spraying pure nitrogen. LiCl·H2O or the anhydrous salt readily absorb moisture in the air and turn into droplet-like forms. The anhydrous LiCl is mainly used for electrolytic production of metallic lithium, soldering and brazing aids, and dehumidifying agents in non-freezing air conditioners. Industrially, it is mainly extracted from lithium mica, lithium spodumene, and the salt brine obtained after extracting NaCl and KCl. Usually, it is produced by reacting Li2CO3 or LiOH with hydrochloric acid. Some chemical reagent factories often obtain anhydrous LiCl as a block-like substance by hot filtration when evaporating the LiCl aqueous solution to 100-110℃, with a moisture content of 3-5%.
