Direct carboxylation of methanol (or ethanol) and product separation by distillation. Use of a pervaporation membrane for water separation and enrichment of the mixture in the carbonate, followed by distillation. Use of CH3CN (at two different concentrations) as organic water trap and product separation by distillation. Conversion in a supercritical system with water separation by formation of a liquid phase.
