Abstract:
The present technology relates to the production and recovery of acetic acid. The recovery processes may include providing a first process stream including acetic acid and greater than 250 ppm of propionic acid; separating at least a portion of the propionic acid from the acetic acid within the first process stream to provide an acetic acid stream including acetic acid and less than 250 ppm of propionic acid and a bottoms stream including propionic acid and acetic acid; reacting the bottoms stream to form a product stream including components of respectively lower boiling points than corresponding components in the bottoms stream; and separating components of the product stream to form an overhead stream including one or more acetates and a bottoms stream including one or more propionates.
