ABSTRACT:
An improved process for making olefins from a lower olefin such as ethylene and an alkyl aluminum by chain growth employes a butene displacement reaction using mixing device such as a static mixer which permits efficient operation of the displacement reaction at moderate pressures where the reactants form a two-phase vapor-liquid system or a vapor system.
