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.

Method for the hydroformylation of olefins comprising 2 to 8 carbons atoms

A process for preparing C -alcohols comprises a) providing a C -hydrocarbon stream comprising butene and butane; b) subjecting the C -hydrocarbon stream to oligomerization over an olefin oligomerization catalyst and fractionating the resulting reaction mixture to give an octene-containing stream and a butene-depleted C -hydrocarbon stream; c) subjecting the butene-depleted C -hydrocarbon stream to steam reforming or partial oxidation to give carbon monoxide and hydrogen; d) hydroformylating the octene-containing stream by means of carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to form C -aldehydes, where the carbon monoxide used and/or the hydrogen used originate at least in part from step c); and e) catalytically hydrogenating the C -aldehydes by means of hydrogen. In a variant of the process, part of the butenes present in the C -hydrocarbon stream are hydroformylated to form C -aldehydes, these are subjected to an aldol condensation and the product of the aldol condensation is hydrogenated to form C -alcohols. The process allows the C -hydrocarbon stream used to be substantially utilized as material.
