Abstract

L'invention se rapporte à la séparation d'acide acrylique à partir de ses solutions dans le phosphate de tri-n-butyle. Le procédé consiste : a. à constituer une phase vapeur comprenant tout l'acide acrylique et une partie du phosphate de tri-n-butyle par chauffage de la solution de départ dans des conditions qui évitent la dégradation du phosphate de tri-n-butyle, b. puis, après condensation partielle ou totale de la phase vapeur, à effectuer, à partir de cette phase, une distillation d'acide acrylique en maintenant dans le pied de la colonne une teneur en acide acrylique suffisante pour éviter la dégradation du phosphate de tri-n-butyle dans les conditions opératoires, c. éventuellement à recycler à l'alimentation du stade a le résidu de distillation du stade b.
