Description
individuellen Kohlenwasserstoffen für die Herstellung von Dienmonomeren durch Dehydrierung oder Pyrolyse verwendet werden.individual hydrocarbons for manufacture of diene monomers can be used by dehydrogenation or pyrolysis.
In den nachstehenden Beispielen wird das Verfahren der r.rfindung näher erläutert.In the examples below, the procedure is the invention explained in more detail.
Beispiel I
Dimerisation des ÄthylensExample I.
Dimerization of ethylene
In einen Glasreaktor, der mit einem Thermometer, Barboteur zur Zuführung des gasförmigen Olefins und mit äui3erer Kühlung versehen ist, wurden im Argonstrom 50 ml tert-Butyltoluol, gereinigt durch Destillation über Natrium, 50 ml Sesquichlorid des Äthylaluminiums sowie 7,5 ml Nickeloleatlösung in Benzol mit einem Gehalt an Nickel von 0,012 g/ml eingebracht und 10 ml Triphenylphosphinlösung in lert-Butyltoluol bei einem Molverhältnis von Triphenylphosphin zu Nickel von 2: 1 hinzugefügt. Der Reaktor wurde in ein Kühlbad eingebracht und Äthylen mit einer Geschwindigkeit von 101/Std. bei einer Temperatur von 20cC und atmosphärischem Druck während 3 Stunden durchgeleitet. Es wurden Butene mit einer Ausbeute von gegen 80 Gewichtsprozent (bezogen auf das umgesetzte Äthylen) bei einer Umwandlung von Äthylen von 48% erhalten. Die Verwendung von Diisobutylaluminiumchlorid statt des Sesquichlorids des Äthylaluminiums und von Di-tertbulylbenzoat statt des Nickeloleats unter sonst gleichen Bedingungen ergab eine Ausbeute an Butenen von 70 bis 75% bei einer Umwandlung von gegen 40%.50 ml of tert-butyltoluene, purified by distillation over sodium, 50 ml of sesquichloride of ethylaluminum and 7.5 ml of nickel oleate solution in benzene were placed in a glass reactor equipped with a thermometer, a barber for feeding the gaseous olefin and with external cooling with a nickel content of 0.012 g / ml and added 10 ml of triphenylphosphine solution in lert-butyltoluene at a molar ratio of triphenylphosphine to nickel of 2: 1. The reactor was placed in a cooling bath and ethylene at a rate of 101 / h. passed through at a temperature of 20 c C and atmospheric pressure for 3 hours. Butenes were obtained with a yield of about 80 percent by weight (based on the converted ethylene) with a conversion of ethylene of 48%. The use of diisobutylaluminum chloride instead of the sesquichloride of ethylaluminum and of di-tertbulylbenzoate instead of the nickel oleate under otherwise identical conditions gave a yield of butenes of 70 to 75% with a conversion of about 40%.

Dimerisation des PropylensExample 2
Dimerization of propylene
Die Reaktion wurde in einem Glasreaktor mit einer Rüttelvorrichtung, der mit einem Druckmesser, einem Thermoelement und einem Kühlmantel versehen war, durchgeführt. In den Reaktor wurden im Argonstrom 15 ml tert-Butyltoluol, 15 ml einer Lösung der in der Tabelle I angegebenen Aluminiumverbindung in n-Heptan, 10 ml einer Lösung von Oleat oder Di-tertbutylbenzoat von Nickel in tert-Butyltoluol eingebracht und 0,45 g Triphenylphosphin in 10 ml tert-Butyltoluol hinzugefügt. Dann führte man bei den in Tabelle I angegebenen Temperaturen und unter Umrühren Propylen aus der Flasche unter einem Druck von 6 at während 1,5 Stunden ein. Das Reaktionsprodukt wurde auf einer Rektifizierkolonne abdestil- liert und Chromatographisch analysiert. Es wurden die in Tabelle I zusammengefaßten Ergebnisse erhalten.The reaction was carried out in a glass reactor with a shaker fitted with a pressure gauge, a Thermocouple and a cooling jacket was provided. In the reactor were in a stream of argon 15 ml of tert-butyltoluene, 15 ml of a solution of the aluminum compound given in Table I in n-heptane, 10 ml of a solution of oleate or di-tert-butyl benzoate of nickel in tert-butyl toluene and added 0.45 g of triphenylphosphine in 10 ml of tert-butyltoluene. Then the in Table I indicated temperatures and stirring propylene from the bottle under pressure of 6 at for 1.5 hours. The reaction product was distilled off on a rectification column. lated and analyzed by chromatography. There were the results summarized in Table I are obtained.
