Abstract
Metal carbonyls are obtained by forming an amalgam of the carbonyl forming metal, subjecting the amalgam to vacuum distillation, to remove mercury therefrom, contacting the metallic residue with a stream of gaseous carbon monoxide, and condensing the metal carbonyl from the gas stream, the amalgam and metal being maintained under non-oxidizing conditions during the above steps. The metallic distillation residue to be treated with carbon monoxide may contain a minor proportion of mercury. Iron, cobalt, and nickel carbonyl may be so prepared. The amalgam may be prepared electrolytically, for example iron amalgam may be prepared by the electrolysis of a solution of ferrous ammonium sulphate using a mercury cathode, the solution being preferably slightly acidified with sulphuric acid, the mercury being kept agitated, and the electrolysis being continued until a relatively thick amalgam is formed. The distillation may be effected at a temperature of 350 DEG C. In the carbonyl formation step atmospheric pressure, and a temperature of 60 DEG C. in the case of iron and of 25 DEG C. in the case of nickel, may be employed.
