A METHOD OF PREPARING VANADIUM HEXACARBONYL, V(CO)6, THIS METHOD COMPRISING REACTING WITH CARBON MONOXIDE A VANADIUM COMPOUND SELECTED FROM THE GROUP CONSISTING OF VANADIUM HALIDES, VANADIUM ACETYLACETONATES, VANADIUM ALKOXIDES, VANADYL HALIDES, AND VANADYL ACETYLACETONATES, IN THE PRESENCE OF A REDUCING SYSTEM COMPRISING: (1) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF THE METALS SODIUM, POTASSIUM, LITHIUM, BERYLINUM, MAGNESIUM, CALCIUM, ZINC, AND ALUMINUM, HYDRIDES OF SAID METALS, ALKYL HYDRIDES OF SAID METALS, AND MIXTURES THEREOF; (2) AN AMINE SELECTED FROM THE GROUP CONSISTING OF PYRIDINE, QUINOLINE, AND TERTIARY AMINES; AND (3) WHEN SAID VANADIUM COMPOUND DOES NOT CONTAIN A HALOGEN, A COMPOUND SELECTED FROM THE GROUP CONSISTING OF ELEMENTARY HALOGENS, HALIDES OF METALS OF GROUPS IV-VIII OF THE PERIODIC TABLE, ALKYL HALIDES, CYCLOALKYL HALIDES, AND ARYL HALIDES; AT A TEMPERATURE OF FROM ABOUT 50 TO 250*C. AND A PRESSURE OF AT LEAST 10 ATMOSPHERES, CONCENTRATING THE RESULTING REACTION PRODUCTS BY EVAPORATION, ACIDIFYING WITH A NON-OXIDIZING ACID TO A PH NOT EXCEEDING 4 TO LIBERATE VANADIUM HEXACARBONYL, AND SEPARATING SAID LIBERATED VANADIUM HEXACARBONYL.
