文摘For producing the pure ethanol,a new method of extractive distillation with alkali was put forward in the paper.According to the vapor-liquid equilibrium experiment,it showed that extractive distillation with alkali was better than extractive distillation with salt.Through the experiment it further proved,comparing with old method,this method can get the product of ethanol over 99.7% with less energy consuming.
