Process for producing carbonyl sulfide |
| abstract |
An efficient process is provided in which sulfur is reacted with carbon monoxide in a liquid phase to produce carbonyl sulfide. In the presence of a base catalyst, carbon monoxide is continuously introduced into a reactor in which a liquid reaction mixture obtained by dissolving or suspending sulfur in an organic solvent is held, and the sulfur is reacted with the carbon monoxide at a pressure of 0.2-3.0 MPa and a temperature of 40-120° C. to yield carbonyl sulfide. The gaseous-phase part is withdrawn from the reactor, and the withdrawn gaseous-phase part is cooled with a cooler to condense the carbonyl sulfide contained in the gaseous-phase part. The condensed carbonyl sulfide is continuously withdrawn, and the gas that has not been condensed with the cooler is returned to the reactor. Thus, carbonyl sulfide is continuously produced. |
