In a two stage process, acetic acid (A) is extracted from water (W) into hexanol (H) in a liquid- liquid extraction vessel and the extract is subsequently separated by distillation. Assume that water is completely insoluble in hexanol. A mixture of 18 wt% acetic acid and the balance water is fed to a liquid-liquid extraction vessel. Pure hexanol is fed to the column to extract the acetic acid. The water-rich stream leaving the vessel is 99.5 wt% water and the balance acetic acid. The hexanol-rich extract from the vessel is fed to a distillation column. The composition of the distillate is 96 wt% acetic acid and the balance hexanol. The bottoms stream contains 97.2 wt% hexanol and recovers 95% of the hexanol fed to the liquid-liquid extraction vessel.
