Abstract: The invention relates to a process for the prepartaion of alkanesulfonic acids, comprising the following steps:(a) oxidation of alkylmercaptans and/or dialkyl disulfides and/or dialkyl polysulfides having from three to nine sulfur atoms with nitric acid to form alkanesulfonic acids, water, nitrogen oxides and other byproducts,(b) regeneration of the nitrogen oxides obtained from step (a) with oxygen to give nitric acid and recycling of the nitric acid to step (a),where steps (a) and (b) are carried out in reaction chambers separate from one another.

Abstract: The invention relates to a method of producing alkane sulfonic acid, comprising the following steps: (a) oxidizing alkyl mercaptans and/or dialkyldisulfides and/or dialkylpolysulfides having three to nine sulfur ato ms with nitric acid to give alkane sulfonic acids, water, nitrogen oxides and further by-products, (b) regenerating the nitrogen oxides obtained in step ( a) with oxygen to give nitric acid and feeding the nitric acid to step (a). Ste ps (a) and (b) are carried out in separate reaction spaces.
