Iron pentacarbonyl is prepared by reacting iron with carbon monoxide in suspension and in the presence of a mixture of alkali metal sulfide and sulfur as a catalyst.

Preparation of iron pentacarbonyl

Iron pentacarbonyl is prepared by reacting iron with carbon monoxide in suspension and in the presence of a polysulfide of the general formula RSR' as a catalyst, where R is an organic radical and x is a number from 2 to 8.

A method for the treatment of catalysts or catalyst carriers by: a) introducing and distributing a gas in the lower section of a reactor containing a catalyst or catalyst carrier bulk material; b) forming a fluidized bed in the reactor; c) treating the particles in the fluidized bed while removing the fine particles an/or retaining the course particles by means of a separating organ and d) discharging the reactor. To this end, a reactor bottom which tapers downwards is used.
