Conclusions
-
1.
The reaction of tetrafluoroethane-β-sultone with H2SO4 was investigated. One of the reaction products was the unstable trifluorovinylsulfuric acid, which decomposes to form difluoroketene.
-
2.
The stability of the alkylpolyfluoroalkenyl sulfates was investigated, and their ability to change into alkyl fluorosulfates was demonstrated.
-
3.
Thermal decomposition of hexafluoropropane-2-β-sultone in the presence of H2SO4 takes place with the formation ofα-hydrotetrafluoropropionyl fluoride.
