ABSTRACT:
A process for dimerizing alpha olefins comprising contacting (i) an alpha olefin having at least 3 carbon atoms, (ii) a hexadentate bimetallic catalyst, and (iii) a cocatalyst, and dimerizing the alpha olefin in a reaction zone at conditions effective to dimerize an alpha olefin to form a reaction zone effluent comprising alpha olefin oligomers including alpha olefin dimers. A process for dimerizing olefins comprising contacting (i) an alpha olefin having at least 3 carbon atoms, (ii) a hexadentate bimetallic complex comprising a cobalt compound, and (iii) a cocatalyst, and dimerizing the alpha olefin in a reaction zone at conditions effective to dimerize an alpha olefin to form a reaction zone effluent comprising oligomers including dimmers, wherein greater than 20 weight percent of the alpha olefin has been converted to oligomers, greater than 30 weight percent of the oligomers are dimers, and greater than 85 mole percent of the dimers are linear.
