ABSTRACT:
Acetone produced during MTBE production and containing methanol, aldehydes and other organic impurities is contacted with a solution of basic material such as NaOH in lower glycol at conditions effective to polymerize aldehyde impurities, the polymerized impurities are separated, and acetone is separated from methanol in an extractive distillation using the same lower glycol as extractive distillation agent.
