Abstract: In a process for producing alkoxybutenes, 1,3-butadiene or a butadienecontaining 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.

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).
