Abstract: The present invention relates to an alkane-sulfonation process using alkane and sulfur trioxide, especially pure sulfur trioxide (100%) under solvent-free conditions in the presence of an initiator. It further relates to the use of a precursor which forms "in-situ" an initiator for manufacturing of alkanesulfonic acids, especially methanesulfonic acids. (Figure 1)
