Method for producing 1-octene from butadiene by dimerizing and
alkoxylating butadiene in the presence of one or more alkoxy substituted
phosphine ligands under alkoxydimerization conditions with an
alkoxydimerization catalyst, the alkoxydimerization conditions being
effective to produce an alkoxydimerization product with one or more
alkoxy substituted octadienes comprising primarily 1-alkoxy substituted
octadiene; hydrogenating the alkoxydimerization product under
hydrogenation conditions effective to produce a hydrogenation product
which is primarily 1-alkoxy substituted octane; eliminating the alkoxy
group from the hydrogenation product under elimination conditions
effective to produce an elimination product which is primarily 1-octene
and a first alkanol having from about 1 to about 3 carbon atoms; and
separating the 1-octene from said elimination product.
