Abstract
Tungsten or molybdenum carbonyl is prepared by reacting an oxychloride of tungsten or molybdenum, or an inferior grade of the chloride of tungsten or molybdenum containing substantial amounts of oxychloride, with carbon monoxide in the presence of not more than 2 per cent of a carbonyl of iron, nickel, or cobalt; alternatively an iron group metal may be present at the start of the reaction, so that the carbonyl is formed as reaction proceeds. The reaction may be carried out in a pressure vessel at 1.500lbs./sq. inch and 100 DEG C in the precence of powdered aluminium or aluminium alloy, e.g. containing copper, aluminium, and zinc, and of ether. In an example the reaction is effected in the presence of anhydrous iron chloride instead of iron or iron carbonyl, which shows that iron in a form unsuitable for making carbonyl during the reaction is not effective in the process.
