Abstract

119,518. Selden Co., and Gibbs, H. D. Oct. 1, 1917. Aldehydes; carboxylic acids; phthalic anhydride; quinones.-The oxidation of aromatic hydrocarbons containing a plurality of side chains or a plurality of rings or their lower oxidation products is effected by passing the vapour of the hydrocarbon mixed with air or other oxygen-containing gas at 250 to 650‹ C. over a catalyst consisting of an oxide of a metal of the fifth or sixth periodic group, for example, antimony, bismuth, chromium, tungsten, uranium, and particularly vanadium or molybdenum. Xylene (o-, m-, or p-) vapour and air passed over vanadium pentoxide at, say, 350 to 550‹ C., give methylbenzaldehydes, phthalaldehydes, benzene dicarboxylic acids, and some toluic and benzoic acid and benzaldehyde; naphthalene vapour treated similarly gives phthalic anhydride and acid, 1 : 4-naphthoquinone, benzoic acid, etc.; anthracene vapour at 350 to 600‹ C. gives anthraquinone. The catalysts may be used singly or mixed, in a state of coarse or fine division, and on a carrier or not.
