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: In the continuous prodn. of alkyl pentenoates (I) by reacting 4 C fractions (II) contg. butadiene (IIA) with alkanols and CO in the presence of Co carbonyl catalysts (III) and heterocyclic aromatic tert. N bases at 100-160 deg.C and 400-1200 bar, the reaction mixt. is passed through a treatment zone, without back-mixing, as it is formed at 100-160 deg.C, pressure of 250-1200 bar and dwell time of 5-60 min.

Abstract: The device for distributing a hydrogenation gas in a hydrogenation reactor consists of a cylindrical reaction part and two spherical ends, the hydrogenation gas and the coal suspended in a liquid being fed together to the hydrogenation reactor via a line arranged centrally in the lower spherical end, and an impingement plate being provided above the outlet of the centrally arranged line in the lower spherical end. With this impingement plate, rapid and uniform distribution of the hydrogenation gas from the cross-section of the feed line to the very much larger cylindrical reactor cross-section is achieved and, at the same time sedimentation of the finely disperse coal is prevented.

Abstract: A method for the continuous production of alkyl esters of pentenric acid by reacting butadiene-containing C4 sections with alkanols and carbon monoxide in the presence of cobalt carbonyl catalysts and heterocyclic aromatic tertiary nitrogen bases at a temperature of 100 to 160 DEG C and under a pressure of 100 to 1200 bar, characterised in that the reaction mixture is passed essentially without remixing through a treatment zone at the rate at which it is formed at a temperature of 100 to 160 DEG C under a pressure of 250 to 1200 bar and with a residence time of 10 to 60 minutes.

Abstract: Expansion valve, consisting of a valve body with an expansion nozzle and a valve tip and of a high-pressure vessel attached to the valve body for the expansion of hydrogenation residues of coal and heavy-oil hydrogenation, in which - the expansion nozzle and the valve tip form a channel narrowing in the expansion direction, - the expansion nozzle has a rounded inlet in the expansion direction, - the smallest diameter of the expansion nozzle is 0.3 to 0.6 times the nominal valve width, and - arranged immediately after the smallest diameter of the expansion nozzle is a conical widening, the total aperture angle of which is > 30 DEG and
