Carbonyls of metals of Groups VI and VII of the Periodic Table according to Mendeleeff and carbonyls of Co and V are produced by carbonylation of the metals or derivatives or salts thereof, salts requiring the presence of Fe and/or Ni and/or other reducing agent with heating under pressure followed by condensation of the carbonyls from the vapour-gas mixture, characterized in that the condensation is carried out while the vapour-gas mixture is simultaneously sprayed with liquid carbonyls of F3 and/or Ni. The vapour-gas mixture may be sprayed with liquid Fe and/or Ni carbonyl formed as by-products in the process of carbonylation of a salt in the presence of Fe and/or Ni. Preferred starting materials are the metals, oxides, hydroxides, or sulphides.
