ABSTRACT:
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.
