The Oxidative Coupling of 2,6-Xylenol Catalyzed by Polymeric Complexes of Copper, 1. Kinetic Study of the Catalysis by Copper(II)-Complexes of Partially Aminated Polystyrene

Abstract: The oxidative coupling reaction of 2,6-xylenol catalyzed by copper(II) complexes of chemically modified polystyrene was investigated. Under the applied reaction conditions the main reaction product was 2,6,2',6'-tetramethyl-1,1'-dioxo-4,4'-bicyclohexa-2,5-dienylidene. It was found that the polymeric complexes behave quite different from the low molecular analogue and that these differences can mainly be ascribed to a better complexation of copper within polymer coils. It appeared that a Michaelis-Menten description of the kinetics fits rather well when the concentration of the phenol was not too high.

Using tert-Butyl Alcohol as an Adductive Agent for Separation of an m-Cresol and 2,6-Xylenol Mixture

Abstract: The solid−liquid equilibrium (SLE) phase boundaries of the ternary mixture of m-cresol, 2,6-xylenol, and tert-butyl alcohol and those of the three constituent binary mixtures were experimentally de...

Process for the synthesis of 2,6-xylenol and 2,3,6-trimethylphenol

Abstract: Phenol is methylated over an alumina catalyst using methanol, and the reaction product therefrom is combined with additional methanol over a promoted magnesium oxide catalyst. Major reaction products are ortho-cresol, 2,6-xylenol and 2,3,6-trimethylphenol. The promoted magnesium oxide catalyst contains metal promoters selected from the group consisting of titanium, chromium, and uranium together with sulfate ions.
