Lithium hydride, 97+%


Chemical Properties

Formula Weight
Melting point
Storage & Sensitivity
Moisture Sensitive. Air Sensitive. Store under Argon. Ambient temperatures.
Reacts violently with water. Soluble in ether, liquid ammonia. Insoluble in benzene, and toluene.


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.


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: H261-H314

In contact with water releases flammable gas. Causes severe skin burns and eye damage.

Precautionary Statements: P223-P231+P232-P260-P264b-P271-P280-P301+P330+P331-P303+P361+P353-P304+P340-P305+P351+P338-P310-P335+P334-P363-P370+P378q-P501c

Keep away from any possible contact with water, because of violent reaction and possible flash fire. Handle under inert gas. Protect from moisture. Do not breathe dust/fume/gas/mist/vapours/spray. Wash face, hands and any exposed skin thoroughly after handling Use only outdoors or in a well-ventilated area. Wear protective gloves/protective clothing/eye protection/face protection. IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER or doctor/physician. Brush off loose particles from skin. Immerse in cool water/wrap in wet bandages. Wash contaminated clothing before reuse. In case of fire: Use CO2, dry chemical, or foam Dispose of contents/ container to an approved waste disposal plant
