ABSTRACT:
According to the process of this invention, saturated mono-alcohols are recovered from solutions containing such mono-alcohols together with a carboxylic acid extraction solvent therefor by passing the mono-alcohol solution to an alcohol vaporization zone, introducing a substantially anhydrous stripping gas to the alcohol vaporization zone in an amount and under conditions sufficient to form vapors comprising the mono-alcohol and to form an alcohol-depleted liquid phase comprising the carboxylic acid extraction solvent.
