Abstract: Oxygen-containing compounds are prepared by oxidizing a hydrocarbon in the liquid phase with a gas containing molecular oxygen, at elevated temperatures and under superatmospheric pressure, by a continuous process in which the said gas is fed into the liquid reaction mixture, in a downward direction, at several points along the reaction zone via nozzle apertures, so that it emerges at each nozzle aperture with a velocity of from 0.01 to 1 m/sec in an amount of from 0.001 to 10 liters per second per nozzle aperture, and the said reaction mixture is brought into substantially uniform contact with the gas containing molecular oxygen, over the volume of the reaction zone.

Abstract: N-(1-4C alkyl)-caprolactams are prepd. by reacting oligomers of caprolactam with 1-4C alkanols, in an alumina vortex layer, in presence of steam at 290-400 deg.C. The ratios by wt. are oligomer:alkanol = 1:0.3-10; oligomer:water (as steam) 1:0.005-10. The pref. alkanol is methanol. The oligomer may be fed as liq. or solid into the Al2O3 vortex layer. gamma-Alumina is pref.
