Preparation of 2,6-xylenol and catalyst composition useful therefor

Abstract: A process for preparing 2,6-xylenol in high selectivity and a catalyst composition useful therein are disclosed. The process comprises reacting phenol, o-cresol or mixtures thereof with methanol in presence of water, hydrogen and a catalyst consisting essentially of Fe 2 O 3 , SnO 2 , Cr 2 O 3 , and K 2 O.

Effect of nonpolar field formed by polymer ligand on the oxidation of 2,6-xylenol catalyzed by Cu complexes

Abstract: The oxidative polymerization catalyzed by Cu(II)-poly(vinylpyridine) derivatives and the effect of the nonpolar field formed by the polymer ligand on the catalysis was studied in dimethyl sulfoxide (DMSO) solvent. The catalytic activity of the Cu complex increases in the following order; Cu-(styrene-vinylpyridine copolymer) (St·VP) complex > Cu-partially quarternized (by benzyl chloride) poly(vinylpyridine)(BCQP) complex > Cu-poly(vinylpyridine) (PVP) complex > Cu-pyridine (Py) complex > Cu-partially quarternized (by ethyl bromide) poly(vinylpyridine) (EBQP) complex. This order is the same as that of the reoxidation rate constant of the catalyst. Acceleration of ko process in Cu-St>VP and Cu-BCQP systems, where the active site is in the nonpolar field formed by the polymer ligand, is explained by an increase in strength of the coordination bonds.

Methylation of 2,6-xylenol to produce 2,3,6-trimethylphenol

Abstract: 2,6-xylenol is methylated to yield 2,3,6-trimethylphenol in high selectivity in a liquid phase reaction controlled in temperature, pressure, and reactor residence time.
