A MIXTURE OF THE STEREOISOMERS OF 4,4''-METHYLENEDI(CYCLOHEXYLAMINE) NOT AT EQUILIBRIUM IS CONVERTED TO A MIXTURE OF STEREOISOMERS APPROACHING EQUILIBRIUM RATIO BY HEATING THE MIXTURE OF STEROISOMERS TO A TEMPERATURE OF FROM 150* TO 300*C. IN THE PRESENCE OF HYDROGEN AT A PARTIAL PRESSURE OF FROM 50 TO 5500 POUNDS PER SQUARE INCH AND AT A TOTAL PRESSURE OF FRM 500 TO 15,000 POUNDS PER SQUARE NCH IN THE ABSENCE OF ADDED AMMONIA AND IN THE PRESENCE OF FROM 0.001 TO 10 WEIGHT PERCENT OF RUTHENIUM CATALYST, CALCULATED AS RUTHENIUM METAL AND BASED ON THE STARTING WEIGHT OF MIXED ISOMERS, THE RUTHENIUM BEING SUPPORTED ON AN INERT CARRIER SELECTED FROM THE GROUP CONSISTING OF CALCIUM CARBONATE; RARE EARTH OXIDES, RARE EARTH CARBONATES AND MIXED RARE EARTH OXIDECARBONATES. |
