Abstract: A process for the preparation of aldehydes or aldehydes and alcohols by hydroformylation of olefins containing more than 3 carbon atoms, comprising a hydroformylation stage, in which the olefin is hydroformylated under a pressure of form 50 to 1000 bar and at a temperature of from 50° to 180° C. by means of a rhodium catalyst dissolved in a homogenous reaction medium and a catalyst recovery stage comprising extraction of the rhodium catalyst with an aqueous solution of chelating agent, isolation of alcohols and/or aldehyde from the extracted hydroformylation product steam, precarbonylation of the aqueous rhodium-containing extract in the presence of carbon monoxide, synthesis gas as, or a gas mixture containing carbon monoxide under a pressure of from 50 to 1000 bar and at a temperature of from 50° to 180° C., separation of the effluent of the precarbonylation stage into an organic phase containing the major portion of the rhodium and an aqueous phase containing the chelating agent and recycling of the organic phase to the hydroformylation stage, where the rhodium catalyst is extracted from the effluent of the hydroformylation stage using an aqueous solution of a sulfonic acid group-free, water-soluble polymer capable of chelating rhodium.

Abstract: In a process for producing n-butylalkyl ethers, (a) 1,3-butadiene or a butadiene-containing hydrocarbon mixture is reacted with an alcohol of formula ROH (I), in which the radical R is a C2-C20 alkyl or alkenyl group substituted or not with 1 to 2 C1-C10 alkoxy or hydroxy groups, a C6-C10 aryl or C7-C11 aralkyl group or a methyl group, at an increased temperature and pressure in the presence of a Brönsted acid or in the presence of a complex of an element of groups Ib, VIIb or VIIIb of the periodic table of elements with a phosphorus- or nitrogen-containing ligand, yielding a mixture of addition products of formulas (II) and (III); (b) the isomers are separated; (c) addition product III is isomerised into addition product II; (d) addition product II is hydrogenated in the presence of a homogeneous or heterogeneous transition metal element catalyst in the liquid phase or in the presence of a heterogeneous, transition metal element-containing catalyst in the gas phase, yielding n-butylalkyl ether of formula (IV).
