Description

General description

The crystal structure of calcium hydride is a slightly distorted hexagonal close packing. At elevated temperatures, calcium hydride acts as a strong reducing agent.1 Solid state reaction between hexachlorobenzene and calcium hydride has been studied in detail.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

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.
