It can serve as a flame colorant to generate dark red flames, a brazing flux for aluminum in automobiles, a hygrometer and a desiccant for drying air streams. On exposure to air, it becomes a solution with the concentration directly related to ... WebLithium chloride is useful for the production of lithium metal and for the generation of Mn(0) species which can be used in free radical cyclizations. It can serve as a flame colorant to … Lithium chloride is mainly used for the production of lithium metal by electrolysis of a LiCl/KCl melt at 450 °C (842 °F). LiCl is also used as a brazing flux for aluminium in automobile parts. It is used as a desiccant for drying air streams. In more specialized applications, lithium chloride finds some use in organic synthesis, e.g., as an additive in the Stille reaction. Also, in biochemical applications, it can be used to precipitate RNA from cellular extracts. エクスプローラー 変更履歴
