Abstract
A process of purifying acetic acid is provided. The process includes feeding a stream of acetic acid into a distillation column and distilling acetic acid in the presence of an oxidizing agent in the distillation column, to oxidize oxidizable impurities in the acetic acid, wherein the oxidizing agent is an oxidant capable of cleaving C═C bonds. The process further includes removing a distilled acetic acid stream from the distillation column. Further processes for purifying acetic acid and systems for purifying acetic acid are also provided.
