FLUORINE-BASED SURFACE-ACTIVE SUBSTANCES Russian patent published in 2015 - IPC C07C309/17 C07C303/06 C07C69/65 B01F17/00 C11D1/00 

FIELD: chemistry.

SUBSTANCE: in general formula

groups Z_i (Z₁, Z₂ and Z₃) independently on each other represent branched or non-branched alkyl groups or groups of structure R_i(A(CR¹R²)_ci(CR³R⁴)_c'i)_di, where respective indices ci and c'i independently on each other represents 0-6, and di=0-5, where R_i represents branched or non-branched fluorine-containing alkyl radical, R¹-R⁴ independently on each other represent hydrogen or branched or non-branched C_1-4alkyl group, ci and c'i are not simultaneously 0, and A=O, Y₁ represents anionic polar group, selected from $$-S{O}_3^{-}$$ , $$-S{O}_3^{-}$$ , $$-P{O}_3^{2-}$$ and $$-P{O}_3^{2-}$$ , and Y₂ represents hydrogen atom, X represents cation, selected from H⁺, alkali metal cation or $$N{R}_4^{+}$$ , where R=H⁺ or C₁-C₆-alkyl, and all R can be identical or different, and, at least, one of groups Z_i represents group of structure R_i(A(CR¹R²)_ci(CR³R⁴)_c'i)_di.

EFFECT: claimed invention relates to compounds of formula (I), containing fluorinated terminal groups, to based on them composition, their application as surface-active substances and to methods of obtaining claimed compounds.
