Aplicação

Calcium hydride (CaH₂) is a metal hydride that can be used for a variety of greener applications such as:

• fabrication of hydrogen storage systems for fuel cell applications
• synthesis of porous aromatic frameworks (PAFs) for adsorption of organic pollutants
• formation of high temperature superconductors

Calcium hydride is widely used as a drying agent for organic solvents.1 It has been used to dry ε-caprolactone,benzene and toluene.
