| titleOfInvention | Method for producing fluosulfonic acid anhydride |
| abstract | The invention relates to a fluorosulfonic anhydride technology 5205 p2 used in organic syntheses, which simplifies the process and increases the yield of fluorosulfonic anhydride. For the production of fluorosulfonic anhydride, chlorine fluorosulfate or peroxydisulfuryl difluoride is treated with carbon monoxide in a fluorosulfonic acid medium containing 20-22% antimony tetrafluoride under normal conditions. In a reactor, a mixture of 4 g of fluorosulfonic acid, 1 g of antimony tetrafluoride and 40 g of chlorine fluorosulfate is bubbled into carbon dioxide at 10 ° C for 1 h. 26.6 g of anhydride are obtained by distillation in 97.5% yield. In a reactor, a mixture of 10 g of fluorosulfonic acid, 2.5 g of antimony tetrafluoride and 39.6 g of peroxydisulfuryl difluoride was bubbled into carbon monoxide at 40 ° C for 1.5 h. 35.6 g of the anhydride are obtained by distillation in 98% yield. 1 3. p.
