Vinylidene olefin is removed from an olefin mixture containing about 1 to 55 mole percent vinylidene olefin, 0 to 20 mole percent internal olefin, and the balance vinyl olefin, by: (A) reacting the olefin mixture in the presence of a BF.sub.3 -water and/or organic promoter catalyst system so as to selectively dimerize said vinylidene olefin, and (B) separating said vinyl olefin and internal olefin from the dimerized vinylidene olefin to produce an olefin product having a reduced vinylidene olefin content compared to said olefin mixture.
本发明提供了一种从含有大约1到55摩尔百分比的
