Abstract

Abstract Translated from German Die vorliegende Erfindung betrifft ein Verfahren zur Gewinnung von 1-Buten aus 2-Butene und gegebenenfalls 1-Buten enthaltenden C4-Kohlen-wasserstoffgemischen durch katalytische Isomerisierung der 2-Butene zu 1-Buten bei erhöhten Temperaturen und Abtrennung des 1-Butens, bei dem man die Isomerisierung der 2-Butene zu 1-Buten in Gegenwart eines sauren Katalysators bei Temperaturen von 150°C bis 500°C durchführt, das aus der Isomerisierungszone erhaltene Isomerisierungsgemisch in eine Destillationszone leitet, am Kopf der Destillationszone 1-Buten abzieht, im unteren Drittel der Destillationszone eine 2-Butene enthaltende Fraktion abzieht und in die Isomerisierungszone leitet und das 2-Butene und gegebenenfalls 1-Buten enthaltende Ausgangs-C4-Kohlenwasserstofgemisch der Destillationszone und/oder Isomerisierungszone zuführt. The present invention relates to a process for the production of 1-butene from 2-butenes and C4-hydrocarbon mixtures optionally containing 1-butene by catalytic isomerization of the 2-butenes to 1-butene at elevated temperatures and removal of the 1-butene, in which the isomerization of the 2-butenes to 1-butene is carried out in the presence of an acidic catalyst at temperatures from 150 ° C. to 500 ° C., the isomerization mixture obtained from the isomerization zone is passed into a distillation zone and 1-butene is drawn off at the top of the distillation zone, in the bottom Withdraws a fraction containing 2-butenes from the third of the distillation zone and feeds it into the isomerization zone and feeds the starting C4-hydrocarbon mixture containing 2-butenes and optionally 1-butene to the distillation zone and / or isomerization zone.
