Title
(DE) VERBESSERTES VERFAHREN ZUR HERSTELLUNG VON TRIACETONDIAMIN UND DESSEN DERIVATEN
(EN) IMPROVED METHOD FOR PRODUCING TRIACETONDIAMINE AND THE DERIVATIVES THEREOF
(FR) PROCÉDÉ AMÉLIORÉ POUR LA PRÉPARATION DE TRIACÉTONEDIAMINE ET DE SES DÉRIVÉS
Abstract
(DE)
Die vorliegende Erfindung betrifft ein verbessertes Verfahren zur Herstellung von Triacetondiamin und dessen alkylsubstituierten Derivaten. Dieses zeichnet sich dadurch aus, dass das Eduktgemisch über einer festen Säure vorbehandelt wird und/ oder die Umsetzung in Gegenwart der festen Säure erfolgt.
(EN)
The present invention relates to an improved method for producing triacetondiamine and the alkyl-substituted derivatives thereof. Said method is characterized in that the educt mixture is pretreated on a solid acid and/or the reaction is carried out in the presence of the solid acid.
(FR)
La présente invention concerne un procédé amélioré pour la préparation de triacétonediamine et de ses dérivés substitués par alkyle. Celui-ci se caractérise en ce que le mélange d'éduits est prétraité sur un acide solide et/ou la transformation a lieu en présence de l'acide solide.
