Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing alkanesulphonic acid by oxidizing an alkyl mercaptan, a dialkyl disulphide and/or a dialkyl polysulphide having three to nine sulphur atoms with an oxidizing agent, wherein additional oxidizing agentis fed into the oxidation if as yet unoxidized alkyl mercaptan and/or unoxidized dialkyl disulphide and/or at least one intermediate from the oxidation of the dialkyl disulphide and/or of the dialkyl polysulphide is present in the reaction output, and a corresponding apparatus for performance of oxidation reactions.
