| 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. |
