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.[1]
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.
