Abstract

La présente invention concerne un procédé de préparation d'amine de triacétone (TAA) qui comprend (i) la réaction d'acétone et d'ammoniac pour produire un produit de réaction comprenant TAA, de l'acétone, de l'oxyde de mésityle et du TMDP ; (ii) l'acheminement du produit de réaction vers une tour de séparation d'acétone pour obtenir un flux d'acétone n'ayant pas réagi ; et un premier flux de fond ; (iii) l'acheminement du premier flux de fond vers une tour de séparation azéotrope pour obtenir un flux de distillat azéotrope contenant des azéotropes aqueux d'oxyde de mésityle et de TMDP ; et un deuxième flux de fond ; (iv) l'acheminement du deuxième flux de fond vers une tour de séparation de chaudière intermédiaire pour obtenir un flux de chaudière intermédiaire ; et un troisième flux de fond ; (v) l'acheminement du troisième flux de fond vers une tour de finition pour obtenir du TAA pur en tant que flux de distillat ; (vi) la soumission du flux de distillat azéotrope à une séparation de phase pour obtenir une phase organique et une phase aqueuse ; l'acheminement de la phase organique vers une tour de séparation de TMDP pour obtenir un flux de distillat de produits recyclables contenant de l'oxyde de mésityle, et un flux de fond contenant du TMDP ; et (vii) le recyclage du flux d'acétone n'ayant pas réagi, le flux de chaudière intermédiaire et le flux de distillat de produits recyclables au moins partiellement à l'étape (i) ; et l'élimination du flux de fond de TMDP.
