Anwendungen & Verwendung
Verwenden
It is used as a absorbent in refrigeration process, as a catalyst, and in photography. It is also useful for organic synthesis, pessat iodination, cleavage of esters, ethers, epoxides, decarboethoxylation, carbonylation, and aldol condensation. It is used for manufacturing medicines and mineral waters. It is used in electochemicstry and redox reactions. Lithium iodide is also a catalyzed conjugate addition reaction of β-dicarbonyl compounds. It is also useful for tetrathioquinodimethane.
Herstellung & Synthese
synthetische
The trihydrate salt is obtained by neutralization of lithium hydroxide or lithium carbonate solution with pure hydriodic acid followed by concentration of the solution for crystallization: LiOH + HI → LiI + H2O When heated in a vacuum, the trihydrate dehydrates to anhydrous salt.
