Procedure

A carboxylic acid is prepared by contacting an aqueous solution of the alkali metal or ammonium carboxylate with a liquid cation exchange agent dissolved in an organic solvent in which the carboxylic acid is substantially water immiscible. As an example, an aqueous solution of trisodium N-(2-hydroxyethyl)ethylenediaminetriacetate is contacted with di(2-ethylhexyl)phosphoric acid in kerosene to thereby form N-(2-hydroxyethyl)ethylenediaminetriacetic acid in the aqueous solution.
