ABSTRACT:
Carbon dioxide is used as a reaction solvent in the hydrogenation of organic compounds. The carbon dioxide is preferably a liquid or a supercritical fluid. The hydrogenation method can be used advantageously in methods for making tetrahydroiso-alpha-acids from alpha-acids, iso-alpha-acids, or beta-acids. If beta-acids are used to make tetrahydroiso-alpha-acids, an acidic lower alcohol is preferably added to the carbon dioxide reaction medium to act as a promoter.
