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: 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 process for preparing a C 13 -alcohol mixture comprises a) bringing a butene-containing C 4 -hydrocarbon stream containing less than 5% by weight, based on the butene fraction, of isobutene into contact with a nickel-containing heterogeneous catalyst at elevated temperature, b) isolating a C 12 -olefin fraction from the reaction mixture, c) hydroformylating the C 12 -olefin fraction by reaction with carbon monoxide and hydrogen in the presence of a cobalt catalyst and d) hydrogenating the product from c). The alcohol mixture is suitable for preparing surfactants by alkoxylation, glycosidation, sulfation, phosphation, alkoxylation and subsequent sulfation or alkoxylation and subsequent phosphation.

Abstract: The invention relates to a method for producing a C13 alcohol mixture, according to which a) a stream of C4 hydrocarbon containing butenes, which includes less than 5 % by weight of iso-butene in relation to the butene fraction, is brought into contact with a heterogeneous catalyst containing a nickel at a raised temperature, b) a C12 olefin fraction is isolated from the reaction mixture, c) the C12 olefin fraction is hydroformulated by being reacted with carbon dioxide and hydrogen in the presence of a cobalt catalyst and d) is hydrated. The alcohol mixture thus obtained is suitable for producing surfactants by alkoxylation, glycosidation, sulphation, phosphation, alkoxylation and subsequent sulphation or alkoxylation and subsequent phosphation.
