Abstract: In the hydroformylation of 2-8 carbon (C) olefins (I), (a) a hydrocarbon charge is subjected to thermal and/or catalytic cracking and/or dehydrogenation; (b) the cracked gas containing olefin or a fraction is separated into streams with higher and lower (I) contents; and (c) the (I)-enriched stream, carbon monoxide and hydrogen are reacted in the presence of hydroformylation catalyst. Unreacted (I) and saturated 2-8 C hydrocarbon are separated and recycled to (b). In the production of hydroformylation products from 2-8 carbon (C) olefins (I), (a) a hydrocarbon charge is fed into a cracking/dehydrogenation zone and subjected to thermal and/or catalytic cracking and/or dehydrogenation, giving a cracked gas containing olefin; (b) the cracked gas or a fraction is separated into streams with higher and lower (I) contents; (c) the (I)-enriched stream, carbon monoxide and hydrogen are fed into a hydroformylation zone and reacted in the presence of a hydroformylation catalyst; and (d) a stream of unreacted (I) and saturated 2-8 C hydrocarbon is separated from the product stream and recycled to stage (b).

Abstract: Essentially monounsaturated polyalkylenes having from 30 to 700 carbon atoms are continuously hydroformylated by a process in which i) a hydroformylation-active cobalt carbonyl catalyst is prepared from a catalyst precursor dissolved in an aqueous phase in the absence of the polyalkylenes, ii) the polyalkylenes are hydroformylated by means of synthesis gas in the presence of the cobalt carbonyl catalyst in a reaction zone, iii) the cobalt carbonyl catalyst is separated from the output from the reaction zone with at least partial reformation of the catalyst precursor and the catalyst precursor is recirculated to step i).

Abstract: The invention relates to a hydroformylation process in which at least one olefin having from 2 to 6 carbon atoms is reacted continuously with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst in a reaction zone in which a liquid phase is present and a stream S) is taken from the liquid phase, heat is removed from this stream and the stream is subsequently returned to the reaction zone without removal of a material component.

Abstract: Hydroformylation of 2-8C olefins comprises: (a) catalytically reacting an olefin containing saturated hydrocarbon (SHC) with CO and H2; (b) separating off a stream of unreacted olefin and SHC and contacting it with an olefin-selective membrane to give an olefin-enriched permeate and an olefin-depleted retentate; and (c) recycling at least part of the permeate back to the reaction zone.

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.

Abstract: Treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, comprises acidifying the wastewater to pH 0-6 and extracting it with an organic liquid produced by stripping the acidified or acidified and extracted wastewater, condensing the stripped compounds and phase-separating the condensate. An independent claim is also included for treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, by acidifying the wastewater to pH 0-6, extracting it with an organic liquid and removing volatile organic impurities and a stripping apparatus, where the organic liquid is a low boiler fraction from the distillation of a crude alcohol produced by hydrogenating an aldehyde, the alcohol/aldehyde being n-butanol/n-butyraldehyde, isobutanol/isobutyraldehyde, n-pentanol/n-valeraldehyde, n- and isopentanol/n- and isovaleraldehyde, 2-ethylhexanol/2-ethylhexenal and/or 2-propylheptanol/2-propylheptenal.
