Process for preparing a sulphonic acid anhydride |
| abstract |
The present invention relates to a process for preparing a sulphonic acid anhydride, and more particularly to the preparation of triflic anhydride. The process for preparing a sulphonic acid anhydride according to the invention is characterized in that it comprises reacting a sulphonic acid or a mixture of two sulphonic acids with a reactant exhibiting pseudo acid halide tautomerism with at least one carbon atom which is involved in the tautomerism bearing two halogen atoms. |
