Abstract
Mercaptans contained in petroleum fractions are oxidized to disulphides by oxygen or a gas containing oxygen in the presence of a catalyst composition containing a sulphur dye and a metal or metal compound. Metal compounds which may be used include salts, hydroxides, oxides, sulphides and chelates of such metals as cobalt, iron, nickel, copper, lead, tin, bismuth, antimony, silver, gold, chromium, manganese, mercury, and vanadium. The catalyst may be prepared by simply mixing the two components or by using a solvent, suitably an aqueous alkaline solution.ALSO:A process for the oxidation of mercaptans to disulphides comprises subjecting a mercaptan to oxidation by oxygen or a gas containing oxygen, e.g. air, in the presence of a catalyst composition comprising a sulphur dye and a metal or metal compound. Mercaptans which may be oxidized are aliphatic, aromatic or heterocyclic in nature and may be contained in petroleum fractions. Metal compounds which may be used include salts, hydroxides, oxides, sulphides, and chelates of metals such as cobalt, iron, nickel, copper, lead, tin, bismuth, antimony, silver, gold, chromium, manganese, mercury and vanadium. Sulphur dyes which may be used include those formed from the reaction of amines, phenols, nitro compounds, heterocyclic compounds with sulphur, sulphides, thiosulphates and sulphur chloride. The catalyst composition may be prepared by simply mixing the two components or by dissolving them in solvents, suitably aqueous alkaline or acid solutions.ALSO:Catalyst compositions comprise a sulphur dye and a metal or metal compound and may be prepared by mixing the components alone or in solution, e.g. in H2SO4 or aq. alkali or by dissolving the sulphur dye in aqueous solutions of sodium sulphide or sodium hydrosulphite or in water alone and adding an aqueous solution of a metal compound followed by the addition of sodium hydroxide solution. Metals which may be used include cobalt, iron, nickel, copper, lead, tin, bismuth, antimony, silver, gold, chromium, manganese, mercury, and vanadium; classes of compounds which may be used include salts, hydroxides, oxides, sulphides and chelate compounds.
