METHOD FOR PRODUCING QUATERNARY SALT PHENOLATE SOLUTIONS AND FOR REGENERATING AND RECYCLING QUATERNARY SALT PHENOLATE SOLUTIONS FROM REACTION MIXTURES

摘要

A process for the preparation of a solution of a quaternary cation and an anion from a deprotonated hydroxy aromatic in an organic solvent by means of a reactive extraction of a quaternary salt in the presence of an aqueous hydroxide solution, a hydroxy aromatic and an organic solvent is disclosed. Also disclosed is a process for the recycling of a quaternary salt phenolate solution from a reaction mixture.
