Abstract
A process of producing an .alpha.-olefin which comprises carrying out separately the growth of ethylene with triethyl aluminum and the growth of ethylene with tributyl aluminum, displacing the resulting higher trialkyl aluminum with ethylene, thereby forming triethyl aluminum and an .alpha.-olefin, and displacing at least part of the resulting triethyl aluminum with butene contained in the resulting .alpha.-olefin, thereby forming tributyl aluminum. The present invention permits the efficient production of .alpha.-olefins containing linear .alpha.-olefins in extremely high purity. The .alpha.-olefins will find use as comonomers for polyolefins (whose demand is increasing recently) and also as raw materials of synthetic lubricants.
