Vapor-phase catalytic oxidation of aβ-picoline fraction

The vapor-phase catalytic oxidation with atmospheric oxidation of a β-picoline fraction consisting of a mixture of 3- and 4-methylpyridines and 2,6-lutidine containing small amounts of 2-methylpyridine and pyridine has been studied. On a vanadium oxide catalyst at 440° C with a contact time of 1.2 sec and a molar ratio of oxygen to steam to methylpyridine of 7 ∶ 54 ∶ 1, a high degree of conversion of the 4-methylpyridine and the 2,6-lutidine into pyridine-4-aldehyde and 6-methylpyridine-2-aldehyde, respectively, has been achieved. The main component of the aqueous solution of the catalyzate (after the isolation of thepyridine aldehydes in the form of oximes) is 3-methylpyridine.
