Patent
CA 2477085
The present invention relates to an improvement in a process for preparing primary amines by hydrogenating nitriles. The improvement in the hydrogenation process is that a hydrogenation catalyst modified ex situ with preadsorbed alkali metal carbonate or hydrogencarbonate such as K2CO3 or KHCO3 is used.
La présente invention concerne une amélioration apportée à un procédé pour produire des amines primaires par hydrogénation de nitriles. Cette amélioration du procédé d'hydrogénation consiste à utiliser un catalyseur d'hydrogénation modifié ex situ avec du carbonate ou de l'hydrogénocarbonate de métal alcalin pré-adsorbé, tel que K2CO3 ou KHCO3.
