Method for producing methanol from carbon dioxide and hydrogen gas in homogeneously catalyzed reactions and in an aqueous medium

The invention relates to a method for producing methanol from hydrogen and carbon dioxide gas in homogeneously catalyzed reactions, composed of the carbon dioxide hydrogenation reaction to formic acid and the formic acid disproportionation reaction into methanol, both being conducted in aqueous media at mild conditions (temperature in the range from 20 to 100 °C, total hydrogen and carbon dioxide gas pressure up to 100 bar).
