    摘要: A process for preparing amines of the formula I, by reacting a carbonyl compound of the formula II with an amine of the formula III where R1 and R2 are different and are each an organic radical which has from 1 to 20 carbon atoms and may optionally also comprise heteroatoms, R3 is a C1-C6-alkyl group and R4 is an aryl group which may be partly or fully halogenated and/or may bear from one to three radicals from the group of cyano, nitro, C1-C6-alkyl, C1-C6-haloalkyl, hydroxyl, C1-C6-hydroxyalkyl, C1-C6-alkoxy, C1-C6-haloalkoxy, hydroxycarbonyl, C1-C6-alkoxycarbonyl, C1-C6-alkylamino, di(C1-C6-alkyl)amino, aryl and aryl(C1-C6-alkyl); and * represents the S or R configuration, and ** represents the S and/or R configuration; which comprises performing the reaction in the presence of a heterogeneous imination catalyst, of a hydrogenation catalyst and of hydrogen.

    摘要: A method for producing 3-pentenenitrile is provided that includes: (a) isomerizing an educt stream containing 2-methyl-3-butenenitrile on at least one dissolved or dispersed isomerisation catalyst to form a stream (1), which contains the isomerisation catalyst(s), 2-methyl-3-butenenitrile, 3-pentenenitrile and (Z)-2-methyl-2-butenenitrile; (b) distilling the stream (1) to obtain a stream (2) as the overhead product, which contains 2-methyl-3-butenenitrile, 3-pentenenitrile and (Z)-2-methyl-2-butenenitrile and a stream (3) as the bottom product, which contains the isomerisation catalyst(s); (c) distilling the stream (2) to obtain a stream (4) as the overhead product, which is enriched with (Z)-2-methyl-2-butenenitrile in comparison to stream (2), and a stream (5) as the bottom product, which is enriched with 3-pentenenitrile and 2-methyl-3-butenenitrile in comparison to stream (2); (d) distilling stream (5) to obtain a stream (6) as the bottom product, which contains 3-pentenenitrile and a stream (7) as the head product containing 2-methyl-3-butenenitrile.
