LIQUID CATION EXCHANGER Russian patent published in 2016 - IPC C07C227/40 C07C229/08 B01D11/04 B01J39/04 B01J39/16 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for removal of organic compounds from aqueous solution. Method includes steps a)-c). Step a) preparing an aqueous solution containing an organic compound and a hydrophobic organic solution, which comprises a liquid cation exchanger, wherein liquid cation exchanger is hydrophobic. Step b) bringing aqueous solution into contact with organic solution. Step c) separating organic solution from aqueous solution. Organic compound is a compound of formula (I) NH₃ ⁺-A-COOR¹ (I), where R¹ represents hydrogen, methyl, ethyl or a negative charge, A is an unsubstituted straight-chain alkylene group with at least three carbon atoms, and liquid cation exchanger is a fatty acid. Disclosed method enables to achieve maximum displacement of equilibrium distribution in direction of hydrophobic organic phase.

EFFECT: invention also relates to reaction mixture for removal of organic compounds from aqueous solution.
