Abstract: The present disclosure relates to a catalyst composition for the oligomerization of ethylene comprising a zirconium-containing catalyst and an organoaluminum-containing co-catalyst. The disclosure also relates to a process for oligomerization of ethylene in the presence of the catalyst composition according to the disclosure. The disclosed process results in C4-C20 linear alpha olefins having improved linearity.

Abstract: Disclosed herein is a method of purifying acetic acid. The method comprises passing a feed stream comprising acetic acid through a distillation column; contacting the acetic acid with a permanganate oxidizing agent and hydrogen gas within the distillation column; withdrawing an acetic acid product from the distillation column; and withdrawing a gaseous product stream from a top portion of the distillation column, wherein the gaseous product stream comprises ethane, methane, carbon dioxide, oxygen, nitrogen, or a combination comprising at least one of the foregoing.
