Abstract: PROBLEM TO BE SOLVED: To inhibit the growth of pop-corn polymer by adding a specific aliphatic alcohol to not-stabilized substance that contains an olefinically unsaturated organic compound and has a tendency of forming pop corn polymer so that the yield, selectivity and the catalyst life is improved advantageously. SOLUTION: An aliphatic alcohol of the formula: ROH (R is a 3-20C alkyl or alkylene), preferably n-butanol is added to a substance that contains an olefinically unsaturated organic compound and has a tendency of forming pop corn polymer, preferably in an amount of 0.1-90 wt.% thereby inhibiting the growth of pop-corn polymer. The olefinically unsaturated organic compound that has a tendency of forming pop-corn polymer has the conjugated diene group and is preferably 1,3-butadiene or isoprene. They may be added batchwise or continuously. The batchwise addition is advantageous in the case where the substance is stored in a tank or transported to a tightly closed vessel.

Abstract: The invention relates to a method for producing n-butyraldehyde and/or n-butanol, whereby a) 1.3 butadiene or hydrocarbon mixtures containing butadiene are reacted with an alcohol of the formula (I) ROH wherein the radical R is an unsubstituted C2- to C20-alkyl- or alkenyl- or a C2- to C20-alkyl- or alkenyl- substituted with 1 to 2 C1- to C10-alkoxy- or hydroxy groups, a C6- to C10-aryl- or a C7- to C11- arylkyl group or methyl group at a high temperature and under high pressure in the presence of a bronsted acid or in the presence of a complex of an element from group IA, VIIA or VIIIA of the periodic table of elements with ligands containing phosphor or nitrogen to form a mixture of adducts of formulae (II) and (III); b) isomerizing adduct (III) to adduct (II); c) converting adduct (III) into acetal of formula (IV) in the presence of a sufficient quantity of an alcohol ROH I to form acetal (IV) and a homogeneous or heterogeneous transitional metal element catalyst which is different from dicobaltoctacarbonyl or hydridocobalttetracarbonyl in the liquid phase in essentially water-free conditions and d) then reacting this acetal (IV) with hydrogen and water or water in the presence of a homogenous or heterogeneous transitional metal element catalyst which is different from dicobaltoctacarbonyl or hydridocobalttetracarbonyl in liquid phase to produce n-butyraldehyde and/or n-butanol and releasing the alcohol ROH I and returning the released alcohol ROH I to the reaction in accordance with partial reaction a) and/or c).

Abstract: The invention relates to a method for producing acetals by reacting allyl ethers with alcohols. According to said method, an allyl ether is reacted with an alcohol in liquid phase in the presence of a homogenous catalyst from an organometallic compound of an element from group VIA and/or VIIIA of the periodic table of elements or in the presence of a heterogeneous catalyst containing one or more elements from the groups IA, VIA, VIIA and/or VIIIA of the periodic table of elements in essentially water-free conditions.

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.
