Abstract

1284839 Polyphenylene ethers ATLAS CHEMICAL INDUSTRIES Inc 24 Nov 1970 [24 Nov 1969] 55820/70 Heading C3R [Also in Divisions C2] Polyphenoxy ethers are prepared by the oxidation of 2,6-dialkyl phenols or monoalkyl phenols by a process which comprises heating a slurry of the phenol, a solvent selected from saturated aliphatic mono-alcohols of two or more carbon atoms and ketones with more than four carbon atoms, and a chelated manganous or cerous compound as the sole catalyst, whilst simultaneously contacting the slurry with an oxygen containing gas so as to intimately contact the oxygen, the catalyst and the reactant.
