    • 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.
    • 通过在烷氧基二聚化条件下用烷氧基二聚催化剂在一个或多个烷氧基取代的膦配体存在下使丁二烯进行二聚和烷氧基化来制备丁烯的1-辛烯的方法,所述烷氧基二聚化条件有效地与一个或多个烷氧基取代的八面体产生烷氧基二聚产物, 主要是1-烷氧基取代的辛二烯; 在有效产生主要为1-烷氧基取代的辛烷的氢化产物的氢化条件下氢化烷氧基二聚产物; 在有效产生主要是1-辛烯的消除产物和具有约1至约3个碳原子的第一链烷醇的消除条件下从氢化产物中除去烷氧基; 并从所述消除产物中分离出1-辛烯。
