ABSTRACT:
Carbon monoxide is reacted with sulfur in the vapor phase at 250.degree.-650.degree. C. to prepare carbonyl sulfide, wherein a reactor is used, in which at least the inner surface is made of an alloy consisting essentially of, based on the weight of the alloy, 20-60% of Cr, 40-65% of Ni, 0-10% of Mo, 0-4% of Nb+Ta, and 0-3% of Fe. The reactor not only possesses good corrosion resistance to the gaseous reaction mixture, but also minimizes the reduction in the purity of carbonyl sulfide produced, which reduction occurs with the lapse of operation time.
