Abstract
The present invention relates to novel uses of stable inorganic peroxoacids as catalysts in the preparation of alkanesulfonic acids from alkanes and sulfur trioxide, methods for the production of alkanesulfonic acids employing said catalysts as well as reaction mixtures comprising said catalysts. The invention particularly relates to the production of methanesulfonic acid from methane and sulfur trioxide employing stable inorganic peroxoacids as catalysts.
Claims17
A process of preparing an alkanesulfonic acid, the process comprising catalyzing a reaction of an alkane and sulfur trioxide with a compound comprising an inorganic peroxoacid or a salt thereof, wherein the inorganic peroxoacid is stable at room temperature.
A process of preparing an alkanesulfonic acid, the process comprising catalyzing a reaction of an alkane and sulfur trioxide with a mixture comprising hydrogen peroxide, an inorganic oxoacid and optionally a solvent.
A mixture comprising an alkane, sulfur trioxide, an inorganic peroxoacid stable at room temperature and optionally a solvent.
A mixture comprising an alkane, sulfur trioxide, an inorganic oxoacid, hydrogen peroxide and optionally a solvent, wherein the inorganic oxoacid is capable of forming an inorganic peroxoacid which is stable at room temperature.
