Process of producing alpha-olefin.

摘要

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. <IMAGE>
