Driving dimethyl carbonate synthesis from CO2 and methanol and production of acetylene simultaneously using CaC2

Abstract

The synthesis of dimethyl carbonate (DMC) from CO₂ and methanol is a very interesting reaction, but is thermodynamically limited. In this work, CaC₂ was used to consume the water produced in the reaction to shift the reaction equilibrium, and C₂H₂ was produced at the same time. This is the first work on the combination of driving a thermodynamically unfavorable reaction and producing C₂H₂ using CaC₂.
