Excerpt from The Chemical News and Journal of Physical Science With Which Is Incorporated the "Chemical Gazette," 1906, Vol. 93: A Journal of Practical Chemistry in All Its Applications to Pharmacy, Arts, and Manufactures The best method of decomposing the compound found to be treatment with alcoholic potash solution in a sealed tube at 100° C. When a bulb containing pure iron carbonyl was broken in alcoholic potash solution, beautiful colourless tabular crystals havings pearly lustre were at once produced at the surface of the liquid these were at once oxidised by the air with the formation of a reddish brown precipitate. The mixture contained in a sealed tube was heated to 100° C. For a short time, the tube cooled, opened (no pressure is produced by this decomposition), the contents washed out, and evaporated to dryness. The residue was treated with nitric acid, again evaporated down, and the iron precipitated by hot caustic potash to separate it from aluminium which was dissolved out of the glass.
