Abstract
1413035 Process for the oxidation of hydrocarbons BAYER AG 19 Oct 1973 [8 Dec 1972] 48827/73 Heading C2C The invention comprises a process for oxidizing a C 4 - to C 20 -hydrocarbon in which the hydrocarbon is reacted with a gas comprising molecular oxygen in the presence of a boron compound; the resulting reaction mixture, containing at least one basic acid ester, is hydrolysed by an aqueous medium containing boric acid; the hydrolysate is separated into a substantially organic component, from which the required oxidation product is obtained, and into a substantially aqueous component, containing boric acid and one or more water-soluble organic secondary products; boric acid is recovered from the aqueous component; the residual boric acid mother liquor, or part thereof, is oxidized in the liquid phase with a gas comprising molecular oxygen at a temperature of at least 200‹ C. and under a pressure sufficient to keep at least some of the water in the liquid phase; and the resulting solution is returned to the hydrolysis medium. The gas for the oxidation of the boric acid mother liquor preferably contains oxygen in at least the stoichiometric quantity sufficient for burning all the organic impurities in a reaction zone heated to at least 200‹ C. under a pressure sufficient to keep at least some of the water in the liquid phase.
