A process is described for preparing 3-pentenenitrile, characterized by the following process steps:

Method for producing linear pentenenitrile

The present invention relates to a composition comprising a pesticide and an alkoxylate. Moreover, the invention relates to the alkoxylate, to a process for its preparation and to its use as adjuvant in pesticide-comprising spray mixtures. The invention furthermore relates to a method of controlling phytopathogenic fungi and/or undesired vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil and/or on undesirable plants and/or the crop plants and/or their environment. Furthermore, the invention relates to seed comprising the composition.

Composition comprising a pesticide and an alkoxylate of iso-nonylamine

A process for preparing O-alkylated amino alcohols by reacting N-unsubstituted or N-monosubstituted amino alkoxide salts with alkyl halides, the amino alkoxide salts being formed by means of alkali metal or alkaline earth metal hydroxides.

Method for producing O-Alkylated aminoalcohols

Composition comprising a pesticide and an alkoxylate of 2-propylheptylamine

The present invention relates to a process for preparing unsymmetric secondary tert-butylamines by continuous amination in the gas phase, wherein tert-butylamine is converted over hydrogenation catalysts in the presence of an alcohol or aldehyde and hydrogen.

Process for preparing unsymmetric secondary tert-butylamines in the gas phase

The present application relates to a process for preparing unsymmetric secondary tert-butylamines which, as well as the tert-butyl radical, also comprise an alkyl, cycloalkyl or benzyl radical. They are prepared by reacting corresponding aldehydes with tert-butylamine and hydrogen in the presence of hydrogenation catalysts (reductive amination) in the liquid phase.

Process for preparing unsymmetric secondary tert-butylamines in the liquid phase

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 isomerization catalyst to form a stream (1), which contains the isomerization 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 isomerization 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.
