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.

Abstract: Manufacture of 6-aminocapronitrile or 6-aminocapronitrile/hexamethylene diamine mixtures, involving a) the reaction of at least one pentennitrile, selected from the group consisting of 2,3 and 4-pentennitrile with carbon monoxide and hydrogen in the presence of catalysts, which contain at least one element of the eighth subgroup as active components, obtaining a hydrogenation formylating discharge (I), b) the optional separation of carbon monoxide, hydrogen and the catalyst from the hydrogenation formylating discharge (I), obtaining a hydrogenation formylating discharge (II), c) the separation of 5formyl valeronitrile from the hydrogenation formylating discharge (I) or (II), d) the reaction of separated 5-formyl valeronitrile with ammonia and hydrogen in the presence of hydrogenating catalysts, selected from the group consisting of rhenium, copper and its compounds as well as metals and metallic compounds of the eighth group, obtaining a hydrogenation discharge, and e) obtaining 6aminocapronitrile and if necessary hexamethylene diamine.

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: The production of 5-formyl valeric acid ester with a yield of not less than 90 % by the distillation of a mixture of 5-formyl valeric acid ester and either 3 or 4-formyl valeric acid ester or a mixture of 3 and 4-formyl valeric acid esters, in which the ester radicals of the formyl valeric acid esters are identical, by separating the 3 or 4-formyl valeric acid esters of their mixtures from the 5-formyl valeric acid ester at a pressure between 2 and 100 mbar and a temperature not exceeding 150 ~C (measured as the column well temperature) in a distillation column, and using the corresponding ethyl or ethyl ester as the esters, and in which the purity of the 5-formyl valeric ester is no lower than 98 % and 4-formyl valeric acid ester is present as an impurity in a quantity of no more than 100 ppm.
