    Abstract: PCT No. PCT/EP95/00825 Sec. 371 Date Sep. 13, 1996 Sec. 102(e) Date Sep. 13, 1996 PCT Filed Mar. 6, 1995 PCT Pub. No. WO95/25080 PCT Pub. Date Sep. 21, 1995An industrial preparation of aldehydes and/or alcohols from olefins of more than 3 carbon atoms by a catalytic hydroformylation of the olefin reactant at a pressure of from 50 to 1000 bar and a temperature of from 50 to 180 DEG C. in the presence of an uncomplexed rhodium catalyst homogeneously dissolved in the reaction medium. The catalytic activity of the rhodium is maintained, first by extracting it from the initially discharged reaction mixture by means of an aqueous solution of a nitrogen-containing complexing agent such as sulfonated or carboxylated pyridines, quinolines or the like. In a recycle of the complexed rhodium to be reused in the hydroformylation reaction, the aqueous rhodium-containing extract is fed to a precarbonylation stage where it subjected to a required precarbonylation in the presence of an essentially water-insoluble organic liquid and in the presence of carbon monoxide, synthesis gas or another gas mixture containing carbon monoxide at from 50 to 1000 bar and from 50 to 180 DEG C. The mixture discharged from this precarbonylation stage is then separated into an organic phase containing the main part of the rhodium and an aqueous phase containing the complexing agent. The resulting rhodium-containing organic phase with the regenerated catalyst is then fed into the hydroformylation stage to complete its recycle.

    Abstract: The proposed process for producing n-butyraldehyde and/or n-butanol involves the following steps: (a) 1,3-butadiene is allowed to react with an amine of formula (I) R R NH, in which the groups independently of one another represent hydrogen, optionally substituted aliphatic or cyclo-aliphatic groups, or aryl or aralkyl groups, or are connected to a bridging unit which can contain heteroatoms, at high temperature and pressure and in the presence of a compound of a group VIIIb element, in the presence of an alkali metal amide, or in the presence of a basic metal oxide, to form a mixture of addition compounds of formula (II) and (III); (b) addition compound (III) is isomerised to addition compound (II); (c) addition compound (II) is isomerised in the presence of a homogeneous or heterogeneous transition metal catalyst in liquid phase or in the presence of a heterogeneous catalyst containing transition metal in the gas phase to produce enamine of formula (IV); and (d) the enamine (IV) is converted, by reaction with hydrogen and water, or water, in the presence of a homogeneous or heterogeneous transition metal catalyst in liquid phase, in the presence of a heterogenous catalyst containing transition metal in the gas phase, in the presence of an acid or in the presence of one of the above mentioned catalysts and of an acid, to n-butyraldehyde and/or n-butanol, the amine (I) being released and the released amine (I) being led back into sub-reaction (a).
