Abstract
Linear alpha-olefin formation via oligomerization of ethylene using transition metal catalysis leads to a Schultz-Flory distribution of oligomers. At modest temperatures formation of heavy oligomers which are waxy solids only partly soluble in the LAO product mix causes reactor plugging and curtailing the time of continuous runs. Recycling a portion of a lighter oligomeric fraction obviates this problem and permits runs uninterrupted by solids formation.
