PROCESS FOR THE ISOMERIZATION OF ALPHA-OLEFIN DIMERS

摘要

A process for isomerization of alpha -olefin dimers which comprises dimerizing a lower alpha -olefin with a Ziegler type catalyst comprising a nickel compound and an organo-aluminum compound, and then continuing the reaction with addition of at least one compound, prior to deactivation of said catalyst, which is selected from the group consisting of the following organo-halogen compounds of the formulae (I), (II), (III) and (IV), (I) (II) (III) (IV) wherein X1 to X11 are the same or different and are each a halogen or hydrogen atom or an alkyl group having 1 to 20 carbon atoms and at least one of them in each formula is a halogen atom, R is a hydrocarbon group having 1 to 20 carbon atoms, R1, R2 and R3 are the same or different and are each a hydrogen or halogen atom or a hydrocarbon group having 1 to 20 carbon atoms, R4 is a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, R5 and R6 are the same or different and are each an alkyl having 1 to 20 carbon atoms or, taken together, may form a cycloalkyl group, and n is an integer of 0 to 5.
