ABSTRACT:
2-Methyl-1-propanol is difficult to separate from 2-methyl-1-butanol by conventional distillation or rectification because of the proximity of their boiling points. 2-Methyl-1-propanol can be readily separated from 2-methyl-1-butanol by extractive distillation. Effective agents are hexyl formate, 2-heptanone and dipropyl amine.
