    Abstract: IN A PROCESS FOR PREPARING ALDEHYDES OR ALDEHYDES AND ALCOHOLS BY HYDROFORMYLATION OF OLEFINS IN THE PRESENCE OF A CATALYST COMPLEX WHICH IS HOMOGENEOUSLY DISSOLVED IN THE REACTION MIXTURE AND COMPRISES A METAL OF GROUP VIIIA OF THE PERIODIC TABLEE OF THE ELEMENTS AND AS LIGAND A PHOSPHORUS-FREE, POLYDENTATE NITROGEN COMPOUND CAPABLE OF COMPLEX FORMATION, AT FROM 50 TO 100oC AND PRESSURES OF FROM 20 TO 1000 BAR, AND RECYCLING OF THE CATALYSTCOMPLEX TO THE HYDROFORMYLATION REACTION, A ) THE LIGANDS USED ARE MODIFIED POLYAMINES WHICH ARE ESSENTIALLY INSOLUBLE IN WATER, ARE CAPABLE OF COMPLEX FORMATION, HAVE A MEAN MOLECULAR WEIGHT OF GREATER THAN 1000 DALTON AND CONTAIN AT LEAST 10 NITROGEN ATOMS, B ) AFTER THE HYDROFORMYLATION REACTION IS COMPLETE AND THE ALDEHYDES AND ALCOHOLS HAVE BEEN SEPARATED OR PARTIALLY SEPARATED FROM THE REACTION MIXTURE BY DISTILLATION, THE CATALYST COMPLEX AND EXCESS LIGAND REMAINING IN THE DISTILLATION BOTTOMS ARE COMPLETELY OR PARTIALLY RECYCLED TO THE HYDROFORMYLATION AND C ) AT LEAST PART OF THE HIGH BOILERS ARE BLED OFF, CONTINUOUSLY OR AT LEAST BATCHWISE, FROM THE BOTTOMS FROM THE DISTILLATION OF THE REACTION MIXTURE.

    Abstract: The invention relates to a method for separating a mixture containing a) a monoethylenically unsaturated compound that can be obtained by adding two terminal olefins carrying the functional groups necessary for producing the monoethylenically unsaturated compound containing at least two functional groups, or a saturated compound obtained by hydrogenating one such compound, b) a compound that can be obtained by adding more than two of the terminal olefins cited in a) or a compound obtained by hydrating one such compound, a nd c) a compound which contains a transition metal, is homogeneous in relation to the mixture, and is suitable as a catalyst for producing a monoethylenically unsaturated compound by adding two terminal olefins carrying the functional groups necessary for producing the monoethylenically unsaturated compound containing at least two functional groups. According to said method, the mixture is separated by means of a semi-permeable membrane, obtaining a permeate and a retentate, in such a way that the weight ratio of constituent b) to constituent c) in the mixture supplied to the semi-permeable membrane is smaller than in the retentate.

    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).
