T-Amyl alcohol cannot be separated from n-butanol by distillation or rectification because of the closeness of their boiling points. T-Amyl alcohol is readily separated from n-butanol by extractive distillation. Effective agents are dimethylsulfoxide, N.N.dimethyl formamide and ethanolamine. Application...
