This invention relates to the formation of metal carbonyls from metal oxides and specially the formation of molybdenum carbonyl and iron carbonyl from their respective oxides. Copper is used here in admixed form or used in chemically combined form as copper molybdate. The copper/metal oxide combination or combined copper is utilized with a solvent, such as toluene and subjected to carbon monoxide pressure of 25 atmospheres or greater at about 150.degree.-260.degree. C. The reducing metal copper is employed in catalytic concentrations or combined concentrations as CuMoO.sub.4 and both hydrogen and water present serve as promoters. It has been found that the yields by this process have been salutary and that additionally the catalytic metal may be reused in the process to good effect.
A catalytic or stoichiometric process for producing a carbonyl from an oxide selected from molybdenum and iron in the presence of copper as free metal, oxide, or chemically combined, which comprises reacting said molybdenum or iron oxide with CO at about 25 atm. or greater and about 150.degree.-260.degree. C. and recovering carbonyl.
A catalytic or stoichiometric process for producing a carbonyl from an oxide selected from molybdenum and iron in the presence of copper as free metal, oxide, or chemically combined, which comprises reacting said molybdenum or iron oxide with CO at about 25 atm. or greater and about 150.degree.-260.degree. C. in the presence of H.sub.2 promoter and recovering carbonyl.
