The present invention relates to novel uses of organic peroxoacids comprising functional groups as catalysts in the preparation of alkane sulfonic acids from alkanes and sulfur trioxide, methods for the production of alkane sulfonic acids employing said catalysts as well as reaction mixtures comprising said catalysts. The invention particularly relates to the production of methane sulfonic acid from methane and sulfur trioxide employing organic peroxoacids comprising functional groups as catalysts. La présente invention concerne de nouvelles utilisations d'acides peroxoacides organiques comprenant des groupes fonctionnels en tant que catalyseurs dans la préparation d'acides alcanesulfoniques à partir d'alcanes et de trioxyde de soufre, des procédés de production d'acides alcanesulfoniques utilisant lesdits catalyseurs ainsi que des mélanges réactionnels comprenant lesdits catalyseurs. L'invention concerne en particulier la production d'acide méthane sulfonique à partir de méthane et de trioxyde de soufre utilisant des peroxoacides organiques comprenant des groupes fonctionnels en tant que catalyseurs.
