ABSTRACT:
1-Propanol is difficult to separate from 2-butanol by conventional distillation or rectification because of the proximity of their boiling points. 1-Propanol can be readily separated from 2-butanol by azeotropic distillation. Effective agents are t-butyl methyl ether, 1,4-dioxane and ethyl formate.
