The distillation separation problem of ethanol-water-chlorobenzene
Thread Content
Ethanol has an azeotrope with water, and water has an azeotrope with chlorobenzene; Aspen contains the corresponding binary interaction parameters indicating the existence of a ternary azeotrope. Ethanol and chlorobenzene do not have an azeotrope together, but it is difficult to separate them, and a high purity of ethanol requires a large reflux ratio. Is this really the case? Have you done it before?
Do you want to obtain three pure substances? In principle, chlorobenzene has a carrying effect on water, and a three-component heterogeneous azeotrope can be formed; therefore, heterogeneous azeotropic distillation can be considered as a solution.
