Title (EN) REACTIVE SEPARATION PROCESS TO CONVERT CYCLIC ALKYLENE UREAS INTO THEIR CORRESPONDING ALKYLENE AMINES
(FR) PROCÉDÉ DE SÉPARATION RÉACTIVE PERMETTANT DE CONVERTIR DES ALKYLÈNE-URÉES CYCLIQUES EN LEURS ALKYLÈNE-AMINES CORRESPONDANTES
Abstract:
(EN) The present invention relates to a process to convert cyclic alkylene ureas into their corresponding alkylene amines by reaction with an amine compound chosen from the group of primary amines or secondary amines that have a higher boiling point than the alkylene amines formed during the process, wherein the process is a reactive separation process and the reaction mixture contains less than 10 wt% of water on the basis of total weight of the reaction mixture.
(FR) La présente invention concerne un procédé de conversion d'alkylène-urées cycliques en leurs alkylène-amines correspondantes par réaction avec un composé amine choisi dans le groupe des amines primaires ou des amines secondaires qui ont un point d'ébullition plus élevé que les alkylène-amines formées pendant le procédé, le procédé étant un procédé de séparation réactive et le mélange réactionnel contenant moins de 10 % en poids d'eau sur la base du poids total du mélange réactionnel.
