Properties
changeLithium aluminium hydride is a colorless solid, but commercial samples are usually gray because of contamination.[2] It can be purified by recrystallization from diethyl ether.[2] It reacts violently with water.[2] Some commercial samples contain mineral oil to stop reactions with moisture in the atmosphere.[2]
Uses
changeLithium aluminum hydride is used in organic chemistry as a reducing agent.[2] Lithium aluminum hydride is most commonly used for the reduction of esters and carboxylic acids to primary alcohols.[3]
