ABSTRACT:
3-Methyl-1-butanol cannot be separated from 1-pentanol by distillation or rectification because of the closeness of their boiling points. 3-Methyl-1-butanol is readily separated from 1-pentanol by extractive distillation. Effective agents are butyl benzoate, 2-undecanone and diethylene glycol methyl ether.
