Zusammenfassung:A HOMOGENEOUS PROCESS FOR THE HYDROGENATION OF DICARBOXYLIC ACIDS AND/OR ANHYDRIDES IN THE PRESENCE OF A CATALYST COMPRISING :(a)RUTHENIUM, RHODIUM, IRON, OSMIUM OR PALLADIUM; AND (b) AN ORGANIC PHOSPHINE;WHEREIN THE HYDROGENATION IS CARRIED OUT IN THE PRESENCE OF AT LEAST ABOUT 1BY WEIGHT WATER AND WHEREIN THE REACTION IS CARRIED OUT AT A PRESSURE OF FROM ABOUT 500 PSIG TO ABOUT 2000 PSIG AND A TEMPERATURE OF FROM ABOUT 200°C TO ABOUT 300°C SUCH THAT FROM ABOUT 1 MOL TO ABOUT 10 MOL OF HYDROGEN ARE USED TO STRIP 1 MOLE OF PRODUCT FROM THE REACTOR.
