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.

Abstract: A method for producing carbon disulfide by sulfurization of sulfur-containing organic compounds is described. Conventional apparatus may be employed with realization of reactant conversion rates approaching 100%, and production of undesirable by-products is insignificant.

Abstract: Process for the synthesis of methyl mercaptan by the reaction of methanol with hydrogen sulfide wherein a high degree of conversion and enhanced selectivity for the product are obtained by dividing the quantity of catalyst utilized in the reaction into a minimum of three separate portions to form a plurality of reactive catalyst zones and introducing the total amount of hydrogen sulfide reagent into the first of such catalyst zones and thereafter introducing equivalent or alternatively different amounts of the methanol reagent into the consecutive interconnected catalytic zones to react with hydrogen sulfide flowing therethrough while maintaining a molar ratio of hydrogen sulfide to methanol between 1.1 and 2.5.
