ABSTRACT:
A mixed olefin feedstock obtained from disproportionating C.sub.8 -C.sub.10 1-olefins can be used as such, i.e. without removal of 1-olefins in a boron trifluoride catalyzed dimerization step to produce synthetic lubricating oils. The results achieved are as good as those achieved using a feedstock from which the undisproportionated 1-olefins have been removed so that this feedstock contains only internal olefins for the dimerization.
