Title
(DE) VERFAHREN ZUR HERSTELLUNG VON UNSYMMETRISCHEN SEKUNDÄREN TERT-BUTYLAMINEN IN DER FLÜSSIGPHASE
(EN) PROCESS FOR PREPARING UNSYMMETRICAL SECONDARY TERT-BUTYLAMINES IN THE LIQUID PHASE
(FR) PROCÉDÉ DE FABRICATION DE TERT-BUTYLAMINES SECONDAIRES ASYMÉTRIQUES EN PHASE LIQUIDE
Abstract
(DE) Die vorliegende Anmeldung betrifft ein Verfahren zur Herstellung von unsymmetrischen sekundären tert-Butylaminen, die neben dem tert-Butylrest noch einen Alkyl-, Cyclo-alkyl- oder Benzylrest enthalten. Ihre Herstellung erfolgt durch Umsetzung entsprechender Aldehyde mit tert-Butylamin und Wasserstoff in Gegenwart von Hydrierkatalysatoren (reduktive Aminierung) in der Flüssigphase.
(EN) The present invention relates to a process for preparing unsymmetrical secondary tert-butylamines which, in addition to the tert-butyl radical, also contain 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.
(FR) La présente invention concerne un procédé de fabrication de tert-butylamines secondaires asymétriques qui, outre le radical tert-butyle, contiennent également un radical alkyle, cycloalkyle ou benzyle. Lesdites tert-butylamines sont obtenues par réaction d'aldéhydes correspondants avec de la tert-butylamine et de l'hydrogène en présence de catalyseurs d'hydrogénation (amination réductrice) en phase liquide.
