THE INTERACTION OF HEXAFLUOROACETIC ACID WITH METHANE SULPHONIC ACID AND WITH SULPHURIC ACID

The reaction between methanesulphonic acid and hexafluoroacetic anhydride yields methanesulphonyltrifluoroacetic anhydride. The reaction of an excess of sulphuric acid with hexafluoroacetic anhydride an a 1:1 mixture of nitromethane and dichloromethane results in the formation of trifluoracetyl hydrogen sulphate.However, at higher concentrations of hexafluoroacetic anhydride, bistrifluoroacetyl sulphate is formed.The rates of the reactions are dependent on the concentration of hexafluoroacetic anhydride and independent of the concentration of the acids when these are in excess.At low concentration of sulphuric acid a more complex relationship is observed.
