Lithium aluminum hydride (LAH), as well as other aluminum and boron hydrides lose their activity due to interaction with moist, oxygen and CO2 even under good storing conditions. Discarding of such deteriorated reagents is neither economical or safe nor environmentally sound.
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.
