Abstract (en)
[origin: WO03055849A1] The invention relates to a method for the production of solutions a quaternary cation and an anion from a deprotonated hydroxy aromatic in an organic solvent by a reactive extraction of a quaternary salt in the presence of an aqueous hydroxide solution, a hydroxy aromatic and an organic solvent, in addition to a method for the recycling of quaternary salt phenolate solutions from reaction mixtures.
