ABSTRACT:
2-Methyl-1-propanol is difficult to separate from 2-butanol by conventional distillation or rectification because of the proximity of their boiling points. 2-Methyl-1-propanol can be readily separated from 2-butanol by extractive distillation. Effective agents are hexyl acetate, dimethyl phthalate and p-xylene.
