(FR) PROCEDE POUR LA SEPARATION PAR DISTILLATION DE MELANGES CONTENANT DU TETRAHYDROFURANE, DE LA $G(G)-BUTYROLACTONE ET/OU DU 1,4-BUTANEDIOL
Abstract: front page image
(DE)Verfahren zur kontinuierlich betriebenen, destillativen Trennung von Tetrahydrofuran, $g(g)-Butyrolacton und/oder 1,4-Butandiol enthaltenden Gemischen in mindestens drei Fraktionen, bei dem man die Trennung in einer Anordnung von Destillationskolonnen, die mindestens eine Trennwandkolonne oder mindestens eine Anordnung von thermisch gekoppelten konventionellen Destillationskolonnen enthält, durchführt.
(EN)The invention relates to a method for continuos distillative separation of mixtures containing tetrahydrofuran, $g(g)-butyrolactone and/or 1,4-butanediol into at least three fractions, wherein separation is carried out in an array of distillation columns containing at least one dividing wall column or at least one array of thermally-coupled conventional distillation columns.
(FR)L'invention concerne un procédé pour séparer par distillation en continu des mélanges contenant du tétrahydrofurane, de la $g(g)-butyrolactone et/ou du 1,4-butanediol. Ce procédé consiste à effectuer la séparation dans un agencement de colonnes de distillation qui comprend au moins une colonne à paroi séparatrice ou au moins un agencement de colonnes de distillation classiques, couplées par voie thermique.
