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.
