Description

CAS: 7580-67-8 | HLi | 7.948 g/mol

Used for preparation of anhydrous Li salts of carboxylic acids prior to reaction with organothium reagents (most often methyl or phenyl) as a useful route to ketones. Also used in the preparation of LiCN by reaction with acetone cyanohydrins. It is also applied as a desiccating and condensing agent and a shielding material in nuclear energy production. It is used in the manufacture of catalysts for polyolefin plastics; in fuels for aircraft, missiles. It is used in metallurgy, as degasifier, deoxidizer, desulfurizer; as grain refiner in non-ferrous metals. Employed as a chemical intermediate for butyllithium polymerization catalyst; in alloys with aluminum or magnesium for aerospace uses.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
