VERFAHREN ZUR HYDRIERUNG EINES UNGESAETTIGTEN ALIPHATISCHEN KOHLENWASSERSTOFFES

摘要

The invention provides a process for the catalytic hydrogenation of an unsaturated hydrocarbon, particularly useful for the hydrogenation of alkynes such as acetylene to alkenes such as ethylene. The unsaturated hydrocarbon is brought into contact with hydrogen in the presence of a catalyst which comprises cations selected from the group consisting in five-coordinate and six-coordinate complex cations of ruthenium (II) having the general formula (1): (RuXLn)+(1) in which: X is a radical; L is a donor ligand; and n is an integer not greater than 5.
