Calcium Carbide (CaC2) as a C2-Synthon by Mechanochemistry.

ChemPlusChem
Mechanochemical reactions by ball milling have opened new avenues in chemical synthesis. Particularly, mechanochemistry has facilitated the reaction of insoluble materials to simplify stablished synthetic protocols and develop new ones.

Thermodynamic Analysis of Calcium Carbide Production

Industrial & Engineering Chemistry Research, 2014
CaC2 production is studied from the viewpoint of thermodynamics using an equilibrium composition model with total Gibbs free energy minimization. It is found that CaC2 is formed directly from the reaction of C and CaO without an intermediate step under the conditions of industrial practice.

Collapsible Gypseous Soil Stabilization by Calcium Carbide Residue and Sulfonic Acid

Sustainability
Gypseous soil is a collapsing soil that has not yet been approved as a construction material since its behavior under water, temperature, and pressure is unreliable and unpredictable.

Construction of pyrazolo[1,5-a]pyrimidines and pyrimido[1,2-b]indazoles with calcium carbide as an alkyne source.

Organic and biomolecular chemistry
An efficient method for the construction of 5-arylpyrazolo[1,5-a]pyrimidines using calcium carbide as a solid alkyne source instead of flammable and explosive gaseous acetylene, pyrazole-3-amine and (hetero)aromatic aldehydes as starting materials in the
