Latest Patents

Shiho Irie holds a patent for a process for producing carbonyl sulfide. This efficient process involves the reaction of sulfur with carbon monoxide in a liquid phase. In the presence of a base catalyst, carbon monoxide is continuously introduced into a reactor containing a liquid reaction mixture of dissolved or suspended sulfur in an organic solvent. The reaction occurs at a pressure of 0.2-3.0 MPa and a temperature of 40-120°C, yielding carbonyl sulfide. The gaseous-phase part is withdrawn from the reactor, cooled to condense the carbonyl sulfide, and continuously withdrawn while returning the uncondensed gas to the reactor. This method allows for the continuous production of carbonyl sulfide.
