ABSTRACT:
2-Butanol is difficult to separate from t-amyl alcohol by conventional distillation or rectification because of the proximity of their boiling points. 2-Butanol can be readily separated from t-amyl alcohol by azeotropic distillation. Effective agents are ethyl acetoacetate, nitroethane and 3-pentanone.
