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 extractive distillation. Effective agents are methyl caproate, adiponitrile and cyclopentanone.
