Abstract: IN A PROCESS FOR PREPARING ALCOHOLS BY CATALYTIC HYDROGENATION OF CARBONYL COMPOUNDS OVER A CATALYST COMPRISING RHENIUM ON ACTIVATED CARBON, THE CATALYST USED COMPRISES RHENIUM (CALCULATED AS METAL) IN A WEIGHT RATIO TO THE ACTIVATED CARBON OF FROM 0.0001 TO 0.5, PLATINUM (CALCULATED AS METAL) IN A WEIGHT RATIO TO THE ACTIVATED CARBON OF FROM 0.0001 TO 0.5 AND, IF APPROPRIATE,AT LEAST ONE FURTHER METAL SELECTED FROM AMONG Zn, Cu, Ag, Au, Ni, Fe, Ru, Mn, Cr, Mo, W AND V IN A WEIGHT RATIO TO THE ACTIVATED CARBON OF FROM 0 TO 0.25, AND THE ACTIVATED CARBON HAS BEEN NONOXIDATIVELY PRETREATED. IT IS ALSO POSSIBLE TO PREPARE ETHERS AND LACTONES IF THE HYDROGEN PRESSURE IS NOT MORE THAN 2500 kPa (25 BAR). IN THIS CASE, THE ACTIVATED CARBON IN THE CATALYST MAY ALSO HAVE BEEN NONOXIDATIVELY PRETREATED.
