The specification discloses a process for the manufacture of carbon disulfide from sulfur dioxide and carbon monoxide comprising two catalytic reactions. In the first reaction, sulfur dioxide and carbon monoxide are converted to carbonyl sulfide and carbon dioxide. In the second reaction, carbonyl sulfide is disproportionated to carbon disulfide and carbon dioxide. The second reaction is conducted in the presence of a solvent, which continuously removes the carbon disulfide product so as to drive the reaction to completion.
