Abstract
Iron carbonyl is produced by treating with carbon monoxide a comminuted initial material containing iron and sulphur which has been prepared by fusion followed by solidification wherein the fused material is cast in layers not thicker than 3 centimetres and quenched either by a water spray, a current of air, by water-cooled moulds or by using iron plates as lining for the casting bed. A sulphur content between 2 and 7 per cent. is preferred in the solidified product. Scrap iron and pyrites or iron sulphide from a previous carbonylation may be fused together or the sulphur may be supplied by copper sulphide, or iron oxide may be fused with pyrites, under reducing conditions, if desired with the addition of sodium sulphate and slag formers. Carbonylation may be effected at 200-220 DEG C at 200 atmospheres pressure, the grain size of the iron sulphide being 5-10 millimetres.
