When heating, it is unstable, decomposition without melting, hydrolysis reaction of sodium hydride with water to prepare sodium hydroxide and hydrogen.Pure sodium hydride is silver needle-like crystals, commercially available sodium hydride merchandise usually is subtle gray crystalline powder, the proportion of sodium hydride is 25% to 50% dispersed in oil. Sodium hydride can be used for condensation and alkylation reaction and can be used as a polymerization catalyst, used for the manufacture of drug synthetic and used in fragrance industry, used for manufacturing boron hydrides, used as metal surface rust, reducing agents, condensing agent, desiccant and Clay Johnson's reagents. Used as a condensing agent, an alkylating agent and a reducing agent, etc. It is an important reductant for Pharmaceutical, perfumes, dyes, but also as a drying age…
