ABSTRACT:
3-Methyl-2-butanol is difficult to separate from 1-butanol by conventional distillation or rectification because of the proximity of their boiling points. 3-Methyl-2-butanol can be readily separated from 1-butanol by azeotropic distillation. Effective agents are methyl acetoacetate and dioxane.
