Abstract
Aromatic hydrocarbons are selectively partially hydrogenated to cyclic olefins by contacting the aromatic hydrocarbon with hydrogen and a ruthenium catalyst in an aqueous dispersion containing a salt of a phosphorus acid.
Claims21
A process for the conversion of aromatic hydrocarbons to the corresponding cyclic olefins which comprises partially hydrogenating an aromatic ring contained within said aromatic hydrocarbon with hydrogen and a ruthenium catalyst at a temperature of 0.degree. to 300.degree. C. under a pressure of 1 to 300 kg/cm.sup.2 in an aqueous dispersion containing a metal salt of a phosphorus acid, wherein said metal is a member selected from the group consisting of Group II to Group VIII metals and wherein said ruthenium catalyst is supported on a solid carrier.
