英文摘要:

      As a very important inorganic and organic synthesis reagents, sodium hydride is widely used in the field of fine chemicals. Due to its reactivity and purity closely related to dispersion, the synthesis of highly reactive sodium hydride was aroused attention in recent years. Several synthetic methods of sodium hydride have been reported, in which the best method of synthesis is to react molten sodium with hydro- gen in mineral oil. The article discusses several synthesis methods of sodium hydride, and describes a brief account on its properties and application.
