A PROCESS FOR PREPARING ALCOHOLS WHICH COMPRISES INTRODUCING INTO A REACTION VESSEL A MIXTURE OF CARBON MONOXIDE, HYDROGEN, AND A HYDROXYLATED SOLVENT OF THE CLASS CONSISTING OF WATER AND PRIMARY HYDROXYALKANES, HEATING THE SAID MIXTURE IN THE PRESENCE OF A RUTHENIUMCONTAINING CATALYST OF THE CLASS CONSISTING OF RUTHENIUM METAL, RUTHENIUM OXIDES AND RUTHENIUM CARBONYLS, AT A TEMPERATURE WITHIN THE RANGE OF 100* TO 250* C. UNDER A PRESSURE WITHIN THE RANGE OF 200 TO 1000 ATMOSPHERES, THE MOL RATIO THE HYDROGEN TO CARBON MONOXIDE BEING INITIALLY FROM 1.5:1 TO 10:1, WHEREBY A REACTION OCCURS RESULTING IN THE FORMATION FROM THE SAID MIXTURE OF CARBON MONOXIDE, HYDROGEN AND HYDROXYLATED SOLVENT OF A MIXTURE OF STRAIGH CHAIN PRIMARY HYDROXYALKANES IN WHICH THE NUMBER OF CARBON ATOMS PER MOLECULE IS WITHIN THE RANGE OF FROM 3 TO 50 AS SUBSTANTIALLY THE ONLY REACTION PRODUCTS, AND THEREAFTER SEPARATING FROM THE RESULTING MIXTURE, HYDROXYALKANES IN WHICH THE NUMBER OF CARBON ATOMS PER MOLECULE IS WITHIN THE RANGE OF FROM 3 TO 50.
