HYDROGENERATION CATALYST AND REACTION USING THE SAME

Japanese Patent JP3560377

B2

PURPOSE: To obtain a catalyst promoting hydrogenation under low temp. and low hydrogen pressure reaction conditions by using a Raney ruthenium catalyst as a catalyst for hydrogenating a part showing aromatic properties contained in a molecule.
CONSTITUTION: A Raney ruthenium catalyst is used as a catalyst for hydrogenating a part showing aromatic properties contained in a molecule of an aromatic hydrocarbon ring or the like. This Raney ruthenium catalyst is a metal catalyst obtained by eluting a metal soluble in alkali or acid from an alloy produced from a metal soluble in alkali or acid such as aluminum or silicon and a metal insoluble in alkali or acid, and the metal compsn. in this metal catalyst is a Rany catalyst based on ruthenium. This catalyst is adapted to benzene, naphthalene or derivatives thereof, pyridine or nitrogen-containing aromatic derivtives. The hydrogenating condition is pref. set so that temp. is 40-150°C and hydrogen partial pressure is 5-10kg/cm2.
