Abstract
2-Methyl-1-propanol cannot be separated from t-amyl alcohol by distillation or rectification because of the closeness of their boiling points. 2-Methyl-1-propanol is readily separated from t-amyl alcohol by azeotropic distillation. Effective agents are butyl propionate, cyclohexane and 2,2-dimethoxypropane.
