  • Mercaptans by addition of hydrogen sulfide to olefins in presence of carbon disulfide
    Patent number: 3963785
    Abstract: In a method for preparing mercaptans by the addition of hydrogen sulfide to olefins in the presence of sulfactive catalysts a method is provided for increasing the total conversion of reactants to mercaptans by including carbon disulfide in the reaction mixture. In a preferred embodiment carbon disulfide is present in the reaction mixture of hydrogen sulfide and ethylenically unsaturated compounds in an amount in the molar ratio of about 5/1 to about 30/1 hydrogen sulfide to carbon disulfide.
