METHOD OF OBTAINING I-BUTENE AND/OR HEXENES

A method of obtaining I-butene and/or hexenes consists in dimerization of ethylene and/or codimerization of ethylene and propylene in an organic solvent at a high pressure and at a temperature of 0-100 DEG C in the presence of a complex metal-organic catalyst containing titanium alcoholate of formul...

Summary:A method of obtaining I-butene and/or hexenes consists in dimerization of ethylene and/or codimerization of ethylene and propylene in an organic solvent at a high pressure and at a temperature of 0-100 DEG C in the presence of a complex metal-organic catalyst containing titanium alcoholate of formula Ti(OR)4, where R is an alkyl radical having 1 to 8 carbon atoms or aryl, trialkylaluminium of formula AlR3, where R is an alkyl radical having 1 to 6 carbon atoms, a magnesium-organic compound of formula MgR2 and/or MgRX, where R is an alkyl radical having 1 to 4 carbon atoms and X is Br, Cl, I. Un procédé d'obtention du butane-I et/ou des héxènes consiste à dimériser de l'éthylène et/ou co-dimériser de l'éthylène et du propylène dans un solvant organique à pression élevée et à une température de 0 à 100°C en présence d'un catalyseur organo-métallique complexe contenant de l'alcoolate de titane ayant la formule Ti(OR)4, où R est un radical alkyle ayant de 1 à 8 atomes de carbone ou de l'aryl, trialkylaluminium de formule AlR3, où R est un radical alkyle ayant de 1 à 6 atomes de carbone, un composé de magnésium organique de formule MgR2 et/ou MgRX où R est un radical alkyle ayant de 1 à 4 atomes de carbone et X représente Br, Cl, I.
