摘要：
ORGANIC AROMATIC NITROGEN CONTAINING COMPOUNDS, SUCH AS P-PHENYLENEDIAMINE OR 4,4''-METHYLENEDIANILINE, CAN BE HYDROGENATED BY ADMIXING THE COMPOUNDS WITH HYDROGEN AT A HYDROGEN PARTIAL PRESSURE OF AT LEAST 200 P.S.I., A TOTAL PRESSURE OF FROM 200 P.S.I. TO 15,000 P.S.I., A TEMPERATURE IN THE RANGE OF FROM 100*C. TO 300*C. IN THE PRESENCE OF FROM 0% TO 200% BY WEIGHT, BASED ON THE WEIGHT OF THE COMPOUND TO BE HYDROGENATED, OF ADDED AMMONIA, AND IN THE PRESENCE OF FROM 0.001% TO 10% BY WEIGHT, BASED ON THE COMPOUND TO BE HYDROGENATED AND CALCULATED AS METALLIC RUTHENIUM, OF A RUTHENIUM CATALYST SUPPORTED ON AN INERT CARRIER SELECTED FROM THE GROUP CONSISTING OF CALCIUM CARBONATE, RARE EARTH OXIDES, RARE EARTH CARBONATES, MIXED RARE EARTH OXIDE-CARBONATES, AND MIXTURES THEREOF.
