FIELD: chemistry.
SUBSTANCE: invention relates to a method of sulphonylating a fluorinated or perfluorinated aliphatic alcohol with a halide of perfluoroalkyl sulphonic acid of formula (II): 
, where R2 is a perfluoroalkyl hydrocarbon group of the type Rf, having the formula CpHaFb, wherein p is a number from 1 to 10; b is a number from 3 to 21 and a+b=2p+1, Z is a fluorine, chlorine or bromine atom, in an organic medium, in the presence of a mineral heterogeneous base selected from ammonium hydroxide or a univalent metal and/or a bivalent metal, a carbonate or bicarbonate of an alkali or alkali-earth metal, in the presence of an apolar organic solvent.
EFFECT: high efficiency of the method.
