Lithium Aluminum Hydride CAS#16853-85-3

Lithium aluminum hydride (LiAlH4) is considered a promising hydrogen storage material due to its high gravimetric and volumetric hydrogen density as well as its relatively low decomposition temperature. Like other metastable hydrides, LiAlH4 cannot be formed through direct hydrogenation under practical hydrogen pressures, leading to significant interest in developing alternative regeneration methods from the dehydrogenated products LiH and Al.

In addition, lithium aluminum hydride is widely used as a reducing agent in the preparation of reduced graphene oxide (rGO).

Product Application of Lithium Aluminum Hydride CAS#16853-85-3

Lithium aluminum hydride (LiAlH4) is a highly effective reducing agent widely used in chemical synthesis. It can reduce esters, carboxylic acids, acyl chlorides, aldehydes, epoxides, and ketones to their corresponding alcohols. In addition, compounds such as amides, nitro compounds, nitriles, imines, oximes, and azides can be converted into amines using LiAlH4.

LiAlH4 is also considered a promising material for hydrogen storage applications due to its high gravimetric and volumetric hydrogen densities. Furthermore, it can be used as a reducing agent in the preparation of reduced graphene oxide (rGO).
