Sodium hydride is the chemical compound with the empirical formula NaH. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis. NaH is a saline (salt-like) hydride, composed of Na+ and H− ions, in contrast to molecular hydrides such as borane, methane, ammonia, and water. It is an ionic material that is insoluble in organic solvents (although soluble in molten Na), consistent with the fact that H− ions do not exist in solution. Because of the insolubility of NaH, all reactions involving NaH occur at the surface of the solid.
Uses: Despite its dangerous reactivity, NaH is widely used as a powerful deprotonating and reducing agent for many organic reactions. It can also be used as a desiccant or drying agent for laboratory chemicals. Due to its ability to release hydrogen gas, it is being explored as a hydrogen storage agent in fuel cell vehicles.
NaH is a base of wide scope and utility in organic chemistry. As a superbase, it is capable of deprotonating a range of even weak Brønsted acids to give the corresponding sodium derivatives. Typical “easy” substrates contain O-H, N-H, S-H bonds, including alcohols, phenols, pyrazoles, and thiols.
Hydrogen storage
Although not commercially significant sodium hydride has been proposed for hydrogen storage for use in fuel cell vehicles. In one experimental implementation, plastic pellets containing NaH are crushed in the presence of water to release the hydrogen. One challenge with this technology is the regeneration of NaH from the NaOH.
The principal use of sodium hydride is to carry out condensation and alkylation reactions which proceed through the formation of a carbanion (base-catalyzed). The sodium hydride dispersion has been evaluated in comparison with dry sodium hydride, sodium metal, sodamide, and sodium methylate.
