Abstract
Abstract Acetone and methanol can not be readily separated by ordinary distillation because of the presence of the minimum boiling azeotrope. Either acetone or methanol can be the overhead product when an appropriate agent is applied in extractive distillation. An unusual phenomenon, “temperature inversion”, was observed when ketones were used as the extractive distillation agents. The dissolving of the vapors into the liquid phase could be the cause for the overhead at a temperature higher than that of the stillpot.
