Abstract:
The present invention refers to a method for the production of haloalkane sulfonic acid, in which SO3 and an haloalkane are contacted with each other in the presence of a solvent, said solvent does constitute a superacid and the combination of said solvent with one or more of the reactants also gives rise to a superacid.
