1. Performance and use
At room temperature, lithium chloride appears as white powder or small particles, and is the most easily deliquescent salt known; The taste is very salty, like chloride; When heated to a dark red color, it melts into a clear liquid, and when heated to white heat, it evaporates.
Lithium chloride has a wide range of applications, and electrolytic production of metallic lithium is the most consumed field of lithium chloride. Currently, the only industrial method for producing metallic lithium is the lithium chloride molten salt electrolysis method proposed by Guntz in 1893. Lithium metal and its alloys and compounds have wide applications in many fields such as atomic energy industry, metallurgical industry, batteries, glass, ceramics, chemical industry, aerospace industry, etc. In recent years, lithium chloride has been widely used in fields such as biology and medicine. In medicine, it is used to treat diabetes, genetic research, etc; Used in biology for the extraction and purification of RNA and small amounts of plasmid DNA; As a mutagen, it is widely used in industries such as food (beer), medicine, and environmental protection to select high-quality strains, cultivate high-yield strains, synthesize pharmaceutical intermediates, and genetically modify strains; In terms of organic structure analysis, LiCl is an important cationic additive; In the field of new materials, it is widely used in the production of chitin; As an adsorbent and dehumidifier in air conditioners and dehumidifiers.
