Abstract: The present invention relates to a method for producing aminocarboxylates starting from amines using a reaction sequence of ethoxylation to form amino alcohols and subsequent oxidative dehydrogenation to form the corresponding aminocarboxylates, in particular the alkali or alkaline earth salts of the complexing agents MGDA (methylglycinediacetic acid), EDTA (ethylenediaminetetraacetic acid) and GLDA (glutamic acid diacetic acid) or the free acids thereof.

Abstract: A process is described for isomerizing pentenenitrile in a reactant stream, wherein the isomerization is effected over a heterogeneous catalyst in a distillation column in such a way that, during the isomerization of the isomerization reactant, it is distillatively depleted in relation to the isomerization product in the reaction column of the distillation column.

Abstract: A process is described for preparing 3-pentenenitrile by hydrocyanating 1,3-butadiene, wherein 1,3-butadiene is reacted with hydrogen cyanide in the presence of at least one catalyst and the stream resulting therefrom is purified distillatively, the bottom temperature during the distillation not exceeding 140° C.
