  • Process for the manufacture of carbon oxysulfide
    Patent number: 4007254
    Abstract: Carbon oxysulfide is obtained in high yield and with high product selectivity and conversion rates by the sulfurization of methanol in the gas phase at elevated temperatures. The starting methanol utilized in the process may be advantageously supplied from natural gas generated at petroleum production sites.

  • Process for preparing hydrogen sulfide
    Patent number: 3961035
    Abstract: The invention is a method for preparing hydrogen sulfide by reacting a gas mixture containing carbon monoxide with sulfur to provide a gas mixture containing carbonyl sulfide and reacting the gas mixture containing carbonyl sulfide with water in the vapor phase to provide a gas mixture containing hydrogen sulfide. The process is preferrably operated continuously. The water can be present in the step in which the carbon monoxide is reacted with the sulfur.
