摘要： A process is provided for the hydrogenation of chloromethanes of the formula CH.sub.n Cl.sub.m, where n=0 to 3 and m=4-n, with hydrogen at a temperature of 150.degree. to 250.degree. C. and under an absolute pressure of 1 to 10 bar, by means of a supported catalyst comprising an activated charcoal support with a BET surface area of more than 500 m.sup.2 /g, 0.5 to 20% by weight of copper in elemental or chemically bonded form and 0.01 to 1.0% by weight of rhodium or palladium in elemental or chemically bonded form, and with 0.1 to 10.0% by weight of a water-soluble phosphonium halide.
