Process for preparing alkylsulfonic anhydrides |
| abstract |
This invention relates to a process for preparing an alkylsulfonic anhydride comprising contacting (A) a dehydrated phosphoric acid with (B) an alkylsulfonic acid having 1 to 6 carbon atoms, under conditions of temperature and pressure to result in the substituted absence of phosphoric/alkylsulfonic mixed anhydride and production of a mixture of alkylsulfonic acid and its corresponding anhydride at a conversion of at least 10% of alkylsulfonic acid to the corresponding alkylsulfonic anhydride. |
