Abstract
Processes for the producing acetic acid and, in particular, to improved processes for removing a cation, such as lithium, and iodides from a low energy carbonylation process to produce purified acetic acid. In one embodiment, the cation, e.g., lithium, may be removed using a cationic exchanger prior to removing iodides using a metal-exchanged ion exchange resin. The present invention is also suited for removing at least one cation selected from the group consisting of Groups IA and IIA of the periodic table, quaternary nitrogen cations, and phosphorous-containing cations.
