Preparation of Sodium Hydride: The preparation of Sodium Hydride involves a precise process. Clean metallic sodium is placed in a reactor (typically steel, porcelain tray, or a hard-melted glass tube). Air is removed from the reactor by passing hydrogen through it. The sodium-containing metal tray is then heated to 370°C, while the hydrogen used is purified by drying over phosphorus pentoxide and passing it through molten sodium. The resulting Sodium Hydride condenses as a white plaque on the colder parts of the tube. While this method yields high-quality Sodium Hydride, it may contain a small amount of metallic sodium as an impurity. Pure crystalline white Sodium Hydride can ignite at 230°C in an oxygen atmosphere, emphasizing the need for careful handling.

Uses of Sodium Hydride: The versatility of Sodium Hydride makes it invaluable across many sectors:

• Owing to its strong base characteristics, Sodium Hydride finds wide application in organic and inorganic fine chemical preparation.
• Sodium Hydride acts as a powerful reducing and deprotonating agent for numerous organic reactions.
• It serves as an effective desiccant or drying agent for many organic reactions, showcasing its broad utility.
• On account of its ability to release hydrogen (Na+H-), the potential of Sodium Hydride as a hydrogen storage agent in fuel cell vehicles is currently being explored.
