Abstract
The present invention relates to a process for the production of alkanesulfonic acid. More particularly, the present invention relates to a process for the production of alkanesulfonic acid from alkyl mercaptan effluents generated in chemical industries. The process of the invention comprises the oxidation of the entire alkyl mercaptan generated as an effluent in the chemical industries to serve two concomitant purposes: (1) complete removal of obnoxious odor, and (2) value addition by the production of alkanesulfonic acids selectively in quantitative yields.
Claims13
A process for the production of an alkanesulfonic acid comprising reacting in situ the corresponding alkyl mercaptan that is generated as an effluent gas in a chemical process and aqueous hydrogen peroxide in the presence of alkanesulfonic acid as a catalyst wherein the alkanesulfonic acid is in the range of 1 to 10 mol % with respect to the alkyl mercaptan.
