Applications

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.

Notes

Air & Moisture Sensitive. Store away from acids, alcohols, oxidizing agents, air, water/moisture. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas.

A procedure for activation involves treatment with TMS chloride and a catalytic amount of Zn or a Zn salt. This reagent will reduce a ketone to the TMS ether of the alcohol: J. Org. Chem., 59, 217 (1994).

GHS Hazard and Precautionary Statements

Hazard Statements: H260-H314-H318

In contact with water releases flammable gases which may ignite spontaneously. Causes severe skin burns and eye damage. Causes serious eye damage.

Precautionary Statements: P210-P231+P232-P262-P280-P305+P351+P338-P308-P310-P378m

Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Handle under inert gas. Protect from moisture. Do not get in eyes, on skin, or on clothing. Wear protective gloves/protective clothing/eye protection/face protection. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. IF exposed or concerned: Immediately call a POISON CENTER or doctor/physician. Use for extinction: Limestone powder.
