Brief Overview
Sodium Hydride is a chemical compound with formula NaH. It is an ionic material that is insoluble in organic solvents (although soluble in molten Na), consistent with the fact that H− remains an unknown anion in solution. Because of the insolubility of NaH, all reactions involving NaH occur at the surface of the solid. It is highly flammable and ignites or explodes in contact with air of high humidity.
Manufacturing Process
Sodium hydride is prepared by passing hydrogen gas into molten sodium metal dispersed in oil. Alternatively, the hydride can be made by passing hydrogen into sodium dispersed over the surface of an inert solid, such as hydrocarbon at above 200°C. The chemical reaction is as follows:
2Na + H2 → 2NaH
