Abstract
Organic compounds of reduced sulphur content and sulphur-free organic compounds can be prepared from organic mercapto and/or disulphide compounds in a particularly advantageous manner by hydrogenolytic elimination of hydrogen sulphide if the elimination of hydrogen sulphide is carried out in the presence of an organic solvent by means of an aqueous, non-oxidizing, strong acid and elemental iron, aluminium and/or zinc in the presence of catalytic amounts of nickel and/or cobalt.
