Abstract
A process is provided for synthesis of dialkylcarbonate, e.g., dimethylcarbonate, by reacting an alcohol, e.g., methanol, with a cyclic carbonate, e.g., propylene carbonate, in the presence of a catalyst comprising an alkaline earth metal halide, e.g., magnesium iodide, and a solid support having a high surface area and controlled surface hydroxyl concentration.
