FIELD: chemistry. ^ SUBSTANCE: invention relates to production of fluorine-containing organic compounds, specifically to a method of producing sulphonylfluorides of perfluorocarboxylic acid fluorides via isomerisation of perfluoroalkane sultones using a gaseous catalyst - trimethylamine, the catalytic amount of which is optimally equal to 0.02-0.14% of the weight of perfluoroalkane sultone. The process is carried out at temperature 0-20C. ^ EFFECT: method provides mild, non-emission reaction, high output of the raw isomer used in synthesis of monomers easily copolymerisable with olefins to obtain polymers for producing ion-exchange membranes for fuel cells, as well as bifunctional semi-products which can be used in several syntheses of fluorine-containing compounds. ^ 3 cl, 3 ex |
