Use
Calcium hydride is a relatively mild desiccant. It is safer than the more reactive agents such as sodium metal. Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine in organic syntheses. It is also used to pre-dry solvents prior to the use of a more reactive desiccant. The compound has, however, been widely used for decades as a safe and convenient means to inflate weather balloons. Likewise, it is regularly used in laboratories to produce small quantities of highly pure hydrogen for experiments.
