Abstract

1326398 Oxidation of dialkyl phenols ATLAS CHEMICAL INDUSTRIES Inc 24 Nov 1970 [24 Nov 1969] 55819/70 Heading C2C [Also in Division B1] 2,6-Dialkyl phenols are oxidized to form a mixture of 2,6-dialkylquinone, the corresponding diphenoquinone and a polyphenoxy ether in which at least 25% of the alkyl groups have been oxidized by heating a mixture of a 2,6-dialkyl phenol, a solvent consisting of tertiary amyl alcohol, tertiary hexyl alcohol or methylisobutyl ketone and a catalyst consisting of a mixture of cupric or ferric nitrate and a salt selected from palladium chloride, palladium acetate, ruthenium chloride or rhodium chloride while simultaneously contacting the mixture with an oxygen-containing gas. The products have the formulae in which X is an alkyl radical; R is alkyl, hydroxyalkyl, carboxyalkyl, alkanoyl or a group COOR, in which R 1 is alkyl or 2,6- dialkyl phenyl, at least 25% of the group R containing hydroxy, carboxy, or carbonyl groups; and n is 2-30. Examples describe the oxidation of 2,6-xylenol, 2-methyl-6-ethylxylenol, and 2,6-dipropyl phenol.
