Description

General description

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.

Calcium hydride is an alkaline earth metal hydride. Its solid state reaction with hexachlorobenzene has been investigated.

Application

Calcium hydride (CaH₂) may be employed as a reducing agent in the one-pot two-step Knoevenagel condensation reaction.
It may also be used as a reagent furing metallothermic synthesis of Nb₃Al.
CaH₂ can be used as a hydrogen source during the synthesis of monomethylated and dimethylated amines and in a ball milling process for the dechlorination of liquid and solid chlorinated compounds.
