FIELD: chemistry.
SUBSTANCE: invention relates to fluorinated compounds, method of their obtaining, fire-extinguishing compositions which include fluorinated compounds, and methods of fire extinguishing, control or prevention by means of said compositions. Fire-extinguishing composition contains solvent and fluorinated compound, representing fluoralkenylpoly[1,6]glycoside and containing C1-C20 fluorocarbon group. Compounds and compositions, described in the document, are useful as intermediate compounds in obtaining compositions of aqueous film-generating foams or as additives to compositions of aqueous film-generating foams, applied in extinguishing burning fuel and solvents.
EFFECT: compounds enhance fire-extinguishing properties and improve foam stability to a considerable degree.
