Extraction from fusel oil of Isopentanol:
Isopentanol can be separated from fusel oil by either of two methods: shaking with strong brine solution and separating the oily layer from the brine layer.
Distilling Isopentanol and collecting the fraction that boils between 125 and 140 °C.
Further purification is possible with this procedure: shaking Isopentanol with hot limewater, separating the oily layer, drying Isopentanol with calcium chloride, and distilling Isopentanol, collecting the fraction boiling between 128 and 132 °C.
