Liquid cation exchanger

摘要

The invention relates to a method for removing an organic compound having one or more positive charges from an aqueous solution. Said method consists of the following steps a) the aqueous solution containing the organic compound, and a hydrophobic organic solution which contains a hydrophobic liquid cation exchanger having one or more negative charges and a negative total charge, are provided, b) the aqueous solution and the organic solution are brought into contact with each other and c) the organic solution is separated from the aqueous solution.

主权项

1. A method for removing an organic compound from an aqueous solution, the method comprising:
a) contacting an aqueous solution comprising an organic compound with a hydrophobic organic solution comprising a hydrophobic liquid cation exchanger, and b) separating the organic solution from the aqueous solution, wherein the organic compound has a formula I
NH3+-A-COOR1  (I), wherein R1 is hydrogen, methyl, ethyl or a negative charge and A is an unsubstituted, linear alkylene group comprising at least three carbon atoms, wherein the liquid cation exchanger is a fatty acid, and wherein the contacting is performed at a temperature of 28 to 70° C.
