Description

Verfahren zur Gewinnung von Butylen Für die Gewinnung von Butylen durcli Polyznerisation von Äthylen in Gegenwart von Kätalysatoren hat man bereits verschiedene Verfahren vorgeschlagen.Process for the production of butylene For the production of butylene The polymerization of ethylene in the presence of catalysts has already been done various procedures proposed.

Es wurde nun gefunden, daß die Polymerisation besonders vorteilhaft verläuft, wenn man hierbei als Katalysatoren Kobalt oder Kobaltverbindungen, z. B. Kobaltoxyde, die sich auf aktiver Kohle befinden, verwendet. Mit derartigen Katalysatoren erhält man bereits bei niedrigen Temperaturen, z. B. bei 20o°, und bei gewöhnlichem Druck einen erheblichen Umsatz des Äthylens zu Butylen. Man erzielt aber auch beim Arbeiten unter höheren Drucken mit den genannten Katalysatoren bessere Ausbeuten als bei Verwendung der üblichen, z. B. aluminiumchloridhaltigen Katalysatoren. Einen für das Verfahren geeigneten Katalysator erhält man z. B. durch Imprägnieren einer aktiven Kohle mit einer Lösung von Kobaltnitrat oder -acetat, Calcinieren und Reduzieren bei möglichst niedrigen Temperaturen, beispielsweise bei 300°.It has now been found that the polymerization is particularly advantageous runs if you here as catalysts cobalt or cobalt compounds, z. B. cobalt oxides, which are on active carbon, are used. With such catalysts is obtained even at low temperatures, e.g. B. at 20o °, and at ordinary Pressure a considerable conversion of the ethylene to butylene. But one also achieves with Working under higher pressures with the catalysts mentioned gives better yields than when using the usual, z. B. aluminum chloride-containing catalysts. A Suitable catalyst for the process is obtained, for. B. by impregnating a active charcoal with a solution of cobalt nitrate or acetate, calcining and reducing at the lowest possible temperatures, for example at 300 °.

Es ist zwar bekannt, daß Äthylen beim Leiten über Kobalt bei Temperaturen von 3oo" an aufwärts, zersetzt wird, daraus kann man aber nicht ableiten, daß man bei Verwendung der vorerwähnten speziellen Katalysatoren und vorwiegend niedrigen, z. T. ganz niedrigen Temperaturen eine Polymerisation des Äthylens zu Butylen bewirken kann.It is known that ethylene when passed over cobalt at temperatures from 300 "upwards, is decomposed, but one cannot deduce from this that one when using the aforementioned special catalysts and predominantly low, z. Sometimes very low temperatures cause the ethylene to polymerize to butylene can.

Beispiel i Über einen Katalysator aus mit Phosphorsäure hergestellter aktiver Kohle, auf der i % Kobalt niedergeschlagen ist, und der bei 300° calciniert und reduziert wurde, wird bei Atmosphärendruck und 2oo° in langsamem Strom Äthylen geleitet. Dabei werden i 9 % des angewandten Äthylens in Butylen umgewandelt.Example i Using a catalyst made from phosphoric acid active coal on which 1% cobalt is deposited and which is calcined at 300 ° and was reduced, is ethylene at atmospheric pressure and 2oo ° in a slow stream directed. During this process, 9% of the ethylene used is converted into butylene.

Beispiel a Man adsorbiert an dem -in Beispiel i angegebenen Katalysator bei o° und unter vermindertem Druck Äthylen. Nach 15 Minuten sind 2-1 %, nach 45 Minuten 61 %, nach 9o Minuten ioo % des vorn Katalysator adsorbierten Äthylens in Butylen umgewandelt. Nimmt man die Behandlung des, Äthylens bei ,25° bzw. 5o° vor, so sind nach 15 Minuten 7 9 bzw. i oo % des adsorbierten Äthylens in Butylen übergegangen. Zur Entfernung des entstandenen Butylens wendet man Vakuum oder mäßig erhöhte Temperaturen oder beide Mittel an und wiederholt dann den Vorgang.Example a Ethylene is adsorbed on the catalyst given in Example i at 0 ° and under reduced pressure. After 1 5 minutes 2-1%, after 45 minutes 61%, of the converted according to 9o minutes ioo% front catalyst adsorbed in ethylene butylene. Taking the treatment of, ethylene at 25 ° or 5o ° before, as five minutes 7 or 9 i oo% of the adsorbed ethylene in butylene have been transferred to the first To remove the butylene formed, use vacuum or moderately elevated temperatures, or both, and then repeat the process.

Beispiel 3 Über einen Katalysator, der aus auf aktiver Kohle niedergeschlagenem Kobalt besteht, wird bei, 25o0 langsam ein Strom von Äthylen geleitet. Dabei werden 5 % des Äthylens in Butylen übergeführt, das durch fraktionierte Kondensation von unverändertem Äthylen abgetrennt wird. - Das wiedergewonnene Ätliyl,en kann dann von neuem über den Katalysator geleitet werden.Example 3 About a catalyst made from precipitated on active charcoal Cobalt is made a stream of ethylene is slowly passed at. 5% of the ethylene is converted into butylene by fractional condensation is separated from unchanged ethylene. - The recovered ethyl can then be passed over the catalyst again.
