Abstract: Disclosed is a method for the hydroformylation of olefins comprising 2 to 8 atoms, whereby a) an inflow containing olefins and a gas mixture containing hydrogen and carbon monoxide are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, b) the reaction product which is released from the raw hydroformylation product is redirected into the reaction zone during the extraction of a gaseous recovery flow. The inventive method is characterised in that c) the recovery flow is brought into intimate contact with a wash liquid in order to eliminate the unreacted olefins contained therein, the wash liquid being a vented hydroformylation product, and the olefin-charged wash liquid and the raw hydroformylation product are redirected for regeneration. Said inventive method enables unreacted olefins to be reclaimed to a large extent from the recovery flow.

Abstract: A liquid output from a continuous hydroformylation, which comprises essentially aldehydes, high-boiling by-products, a homogeneously dissolved hydroformylation catalyst, unreacted olefins, low-boiling by-products and dissolved synthesis gas, is worked up by a process in which a) the liquid hydroformylation output is depressurized in a first depressurization stage to a pressure which is from 2 to 20 bar below the reactor pressure, resulting in separation into a liquid phase and a gas phase, and b) the liquid phase obtained in the first depressurization stage is depressurized in a second depressurization stage to a pressure which is lower than the pressure of the first depressurization stage, resulting in separation into a liquid phase comprising essentially high-boiling by-products of the hydroformylation, the homogeneously dissolved hydroformylation catalyst and small amounts of hydroformylation product and unreacted olefin and a gas phase comprising essentially the major part of the hydroformylation product, unreacted olefin and low-boiling by-products.

Abstract: Disclosed is a method for the hydroformylation of olefins comprising 2 to 8 carbon atoms, whereby (i) an inflow containing olefins and an added saturated hydrocarbon comprising 2 to 8 carbon atoms, as well as carbon monoxide and hydrogen, are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, (ii) a flow consisting essentially of unreacted olefins and saturated hydrocarbons is separated from the discharge from the reaction zone, (iii) said flow is separated into an olefin-enriched fraction and an olefin-depleted fraction by means of rectification, and (iv) the olefin-enriched fraction is at least partially redirected into the reaction zone.

Abstract: A process for preparing hydroformylation products of propylene and for preparing acrylic acid and/or acrolein comprises a) feeding a propylene-containing feed in which from 2 to 40% by weight of propane is present and also carbon monoxide and hydrogen into a reaction zone and reacting this mixture in the presence of a hydroformylation catalyst to form hydroformylation products of propane, b) separating a stream consisting essentially of unreacted propylene and propane from the output from the reaction zone, and c) subjecting the stream consisting essentially of propylene and propane to a catalytic gas-phase oxidation in the presence of molecular oxygen to form acrylic acid and/or acrolein.

Abstract: Mixtures containing cyclohexyl hydroperoxide, cyclohexanol and cyclohexanone and having a high cyclohexyl hydroperoxide content are prepared by a continuous process which comprises the oxidation of cyclohexane with molecular oxygen, or with a gas containing this, in the liquid phase, in which 1. in a first stage, molecular oxygen is dissolved in cyclohexane by bringing the latter into contact with molecular oxygen, or with a gas containing this, at from 10 to 110.degree.C and under superatmospheric pressure, and 2. in a second stage, the cyclohexane containing dis solved molecular oxygen is passed through an elongated, tubular reaction zone at from 130 to 250.degree.C and under superatmospheric pressure, virtually with plug flow and without the formation of a gas phase, the residence time being between a) the time required for the consumption of 50% of the amount of dissolved molecular oxygen and b) 1.2 times the time required for the consumption of 99.9% of the dissolved molecular oxygen.

Abstract: Aromatic nitriles, in particular phthalodinitriles, are prepared from an appropriately alkyl-substituted aromatic hydrocarbon by catalytic oxidation with oxygen or an oxygen-containing gas in the presence of ammonia at elevated temperatures in the vapor phase, in the presence of a catalyst which contains from 2 to 10% by weight of vanadium(V) oxide, from 1 to 10% by weight of antimony(III) oxide, from 0.02 to 2% by weight of an alkali metal oxide and alumina, by a process in which from 0.01 to 1.0% by weight of an alkaline earth metal, or of a compound of an alkaline earth metal, in particular barium or a barium compound, is added to the catalyst.
