Abstract: The process for removing and reusing the amine, complexing and metal components from the waste water from catalyst removal, which are produced in the preparation of high molecular weight polyphenyl ethers in the presence of an organic solvent and are obtained by treating the solution with aqueous complexing agents, entails making the aqueous phase alkaline and separating out the amine which deposits, removing the complexing agent and precipitating the copper ions from the filtrate.

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.

Abstract: Polyphenylene ethers are prepared from monohydric phenols, which possess alkyl substituents in the two ortho-positions and, if desired, in the meta-position, but not in the para-position, by an oxidative coupling reaction with oxygen at from 15 DEG to 50 DEG C. and under from 1 to 10 bar in the presence of a catalyst complex, of a solvent and, if required, of an activator, by a method in which the conversion of the phenols is carried out in two more reaction zones, in which some or all of the solvent, the catalyst complex and the phenols and, where relevant, the activator is initially taken and is circulated by means of a conveying unit, and about 60-100% of the stoichiometric amount of oxygen required for the oxidative coupling is introduced into the first reaction zone and from 0 to about 40% of the said stoichiometric amount is introduced into the second reaction zone.
