Application

Lithium aluminum hydride (LiAlH4) is an effective reducing agent that can be used in chemical synthesis to reduce esters, carboxylic acids, acyl chlorides, aldehydes, epoxides, and ketones into the corresponding alcohols. In addition, amide, nitro, nitrile, imine, oxime, and azide compounds are converted into amines.
LiAlH4 is a promising substance for hydrogen storage applications. Its properties include high gravimetric and volumetric hydrogen densities . It can also be used as a reducing agent in the preparation of reduced graphene oxide (rGO).
