Abstract:
1. A process for the dimerization of olefins comprising the steps of: modifying a support material containing —OH groups with an alkylaluminum compound to form a modified support material; mixing an ionic liquid having a melting point below about 100° C. with a buffer to form a buffered ionic liquid; mixing the buffered ionic liquid with an organometallic complex of the formula where X is a halogen, n=2 or 3, M=Ti, V, Cr, Mn, Co and Ni and R1, R2, R3 and R4 are selected from the group consisting of hydrogen, alkyl, aryl, alkenyl, alkynyl, alkyloxy, substituted aryl, and X to form a buffered ionic liquid/catalyst complex; mixing the buffered ionic liquid/catalyst complex with the modified support material to form an immobilized buffered catalyst; and mixing the immobilized buffered catalyst with one or more alpha-olefins.
