    Abstract: In a process for producing n-butyraldehyde and/or n-butanol, (a) 1,3-butadiene is reacted with an alcohol having the formula ROH, in which the residue R stands for a non-substituted C2-C20-alkyl or alkenyl group that may also be substituted by 1 or 2 C1-C10-alkoxy or hydroxy groups, a C6-C10-aryl or C7-C11-aralkyl group or the methyl group, at a higher temperature and pressure in the presence of a Brönsted acid or in the presence of a compound of an element from groups IB, VIIb or VIIIb of the periodic table of elements with phosphoric or nitrogenated ligands, so as to produce a mixture of addition compounds having the formulas (II) and (III); (b) the addition compound III is isomerised into the addition compound II; (c) the addition compound II is isomerised in the presence of a homogeneous or heterogeneous transition metal element catalyst in liquid phase or in the presence of a heterogeneous transition metal element-containing catalyst in gaseous phase, so as to produce an enol ether having the formula (IV); and (d) n-butyraldehyde and/or n-butanol are generated by reacting said enol ether IV with hydrogen and water or with water 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 gaseous phase. The alcohol ROH released is recycled into the partial reaction (a).

    Abstract: The invention relates to a method for producing formic acid by generating the corresponding ammonium formate by means of catalytic hydrogenation of c arbon dioxide with hydrogen on a catalyst comprising a metal of groups 8 thr ough 10 of the periodic system, in the presence of a primary, secondary, and /or tertiary amine, and by cleaving the ammonium formate by heating it in fo rmic acid and the amine, characterized in that the primary, secondary, or te rtiary amine is selected from the amines of formula I or the mixtures thereo f, R1 through R3 being identical or different and being hydrogen, linear or branched alkyl radicals having 1 to 18 carbon atoms, cycloaliphatic radicals having 5 to 7 carbon atoms, aryl radicals and/or aryl alkyl radicals, at le ast one of the radicals R1 to R3 carrying a hydroxyl group, and that said hy drogenation is performed in a solvent having a boiling point of >=105°C a t normal pressure, and that the formic acid is obtained in the hydrogenation reaction mixture comprising the high-boiling solvent by thermal cleavage of the ammonium formate and distillation of the formic acid.

    Abstract: A system comprising a diphosphine of the formula R 1 >P-(CH) n -PR 2 R 3 where R 1 is a divalent radical which together with the phosphorus atom to which it is linked forms an unsubstituted or substituted 2-phosphatricyclo[3.3.1.1{3,7}]decyl group or a derivative thereof in which one or more of the carbon atoms are replaced by heteroatoms, R 2 , R 3 are each, independently of one another, a monovalent radical having from 1 to 20 atoms or together form a divalent radical having from 2 to 20 atoms, n is 4 or 5, and a mixture of such diphosphines, and palladium or a palladium compound is suitable as carbonylation catalyst for the carbonylation of a conjugated diene.

    Abstract: A process for separating a mixture comprising a) a monoolefinically unsaturated compound which is obtainable by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, or a saturated compound obtained by hydrogenating such a compound, b) a compound which is obtainable by adding more than two of the terminal olefins mentioned in a) or a compound obtained by hydrogenating such a compound, and c) a compound which contains a transition metal, is homogeneous with respect to the mixture and is suitable as a catalyst for preparing a monoolefinically unsaturated compound by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, by means of a semipermeable membrane to obtain a permeate and a retentate in such a way that the weight ratio of component b) to component c) in the mixture fed to the semipermeable membrane is smaller than in the retentate.
