Applications

Sodium hydride is used to enhance the condensation reactions of carbonyl compounds through the Dieckmann condensation, Stobbe condensation, Darzens condensation and Claisen condensation. It acts as a reducing agent used to prepare diborane from boron trifluoride. It is also used in fuel cell vehicles. Further, it is used to dry some organic solvents. In addition to this, it is involved in the preparation of sulfur ylides, which is utilized for the conversion of ketones into epoxides.

Notes

Air and moisture sensitive. Incompatible with alcohols, water, oxidizing agents, acids, halogens, oxygen, acetylene and sulfur compounds.
