Abstract: A process for preparing alkanesulfonic acids from sulfur trioxide and an alkane, wherein sulfur trioxide, the alkane and dialkylsulfonoyi peroxide (DASP) react as components, characterized in that the following steps are performed: a) sulfur trioxide is charged in a high-pressure reactor in a condensed phase; b) a temperature of at least 25° C. is set; c) the gaseous alkane is introduced to the high-pressure reactor until a pressure of at least 10 bar is reached; d) dialkylsulfonoyi peroxide (DASP) is added; and e) after a duration of at least 5 hours, the produced alkanesulfonic acid is withdrawn.
