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: Method for production of n-butylamines involves hydroamination of a butadiene-containing mixture (from cracking fractions, LPG/LNG dehydrogenation or GTL technology) with a primary or secondary amine in presence of alkali metal or metal amide catalyst, followed by transalkylation and hydrogenation. Method for the production of n-butyl-amines (I) from a 1,3-butadiene-containing mixture (II) obtained by cracking petroleum fractions or from the dehydrogenation of LPG or LNG or from GTL technology, involves: (a) reaction of (II) with a primary and/or secondary amine (III) under hydroamination conditions in the presence of alkali metal, metal monoalkylamide, metal dialkylamide or a metal amide of amine (III) as catalyst; (b) reaction of the hydroamination product under transalkylation conditions; and (c) reaction under hydrogenating conditions.

Abstract: The olefin is introduced into the bottom zone of the hydroformylation reactor contg. a liq. reaction zone making up 60-85% of the reactor vol., at 1-40 bar and 50-140 deg. C, using Rh complex cpds. as catalysts. The gaseous reaction prods. and reaction partners are removed from the hydroformylation reactor. The reaction prods. are sepd. and most of the remaining gas is returned to the reactor as recycle gas. The novelty consists in charging 20-80 vol.% of the recycle gas to the hydroformylation reactor above the liq. reaction zone and/or below the liq. surface in the top quarter of the liq. reaction zone.
