FIELD: chemistry.
SUBSTANCE: present invention relates to process variants for the preparation of a halogenated fluorinated ether-containing compound that can be used to prepare peroxide curable elastomers. One of the process variants comprises the following steps: (i) halogenating the difluorosulfuryl peroxide followed by reaction with the first fluoroolefin to form a halogenated fluorine organic acid fluoride; (ii) reacting the halogenated fluorocarbonic acid fluoride with a first compound selected from at least one of: (a) a second fluoroolefin in the presence of a halogenated compound to form a halogenated fluorinated ether-containing compound; and (b) hexafluoropropylene oxide (HFPO) to form the corresponding acid fluoride and converting the corresponding acid fluoride to a halogenated fluorinated ether-containing compound.
EFFECT: proposed invention makes it possible to obtain target products using a simplified technology.
