Extractive Distillation of Ethanol-Cyclohexane Azeotrope Using Ionic Liquid as Extractant
|
Abstract:
The effect of different ionic liquids on relative volatility of ethanol-cyclohexane system was examined at 0.101 MPa.The effects of solvent ratio on relative volatility of ethanol-cyclohexane system,and flow rate of ionic liquid and reflux ratio on purity and output of overhead fraction of the extractive distillation column with ionic liquid were studied.Repeated experiments were carried out under the optimum experimental conditions.The results show that the azeotropic point of ethanol-cyclohexane system is...
