(FR) PROCÉDÉ ET APPAREIL POUR ÉLIMINER LES ALDÉHYDES PRÉSENTS DANS DE L'ACÉTONE
Abstract:
(EN) The present invention relates to process and apparatus for removing aldehydes from acetone. More specifically, the present invention relates to a process and apparatus for removing aldehydes from acetone by reacting the aldehydes with caustic in an acetone column and washing the organic phase with a plurality of water streams.
(FR) La présente invention se rapporte à un processus et un appareil permettant d'éliminer les aldéhydes présents dans de l'acétone. Plus spécifiquement, la présente invention concerne un processus et un appareil permettant d'éliminer les aldéhydes présents dans de l'acétone, par une réaction des aldéhydes avec une susbtance caustique dans une colonne d'acétone et le lavage de la phase organique avec une pluralité de courants d'eau.
