Linear 1-olefins are continuously prepared from internal olevins by (i) continuously feeding internal olefin, isomerization catalyst and tri-lower alkyl aluminum to a reaction zone so as to cause the internal olefin to isomerize to 1-olefins which displace the lower alkyl groups to form a trialkyl aluminum compound in which at least one of the alkyl groups is a linear alkyl derived from the 1-olefin, (ii) continuously removing trialkylaluminum compound from the reaction zone and, thereafter, (iii) reacting the trialkyl aluminum compound with a 1-olefin so as to displace the linear alkyl from the trialkyl aluminum compound, thereby forming a linear 1-olefin product which is substantially free of internal olefins.
