Abstract: The invention relates to a process for removing and recycling the amine, complexing and metal components from the catalyst-separation effluent produced in the preparation of high-molecular-weight polyphenylene ethers in the presence of an organic solvent and obtained by treating the solution with aqueous complexing agents, treating the aqueous phase with a strong acid and separating off the complexing agent, separating off the copper ions from the aqueous phase by precipitation with sulphide ions or by electrolytic deposition of the copper in an electrolysis cell, deposition of the amine by addition of a base, which causes the pH to be adjusted to > 11, separating off the amine and reusing the amine as a catalyst component.
