    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) R1R2NH, 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).

    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).

    Abstract: In a process for producing alkoxybutenes, 1,3-butadiene or a butadiene-containing hydrocarbon mixture is reacted with an alcohol of formula ROH (I) at an increased temperature and pressure in the presence of a Brönsted acid, yielding a mixture of addition products of formulas (II) and (III), in which the radical R is a C2-C20 alkyl, alkenyl, cycloalkyl or cycloalkenyl group substituted or not with 1 to 2 C1-C10 alkoxy or hydroxy groups, or is a C2-C10 aryl or C7-C11 aralkyl group or a methyl group. The disclosed improvement consists in that the reaction is carried out in the presence of water.
