ABSTRACT:
T-Amyl alcohol and 2-methyl-1-propanol are difficult to separate by conventional distillation or rectification because of the proximity of their boiling points. T-Amyl alcohol can be easily separated from 2-methyl-1-propanol by extractive distillation. Effective agents are N,N-dimethylacetamide, cyclohexyl amine and glycerol.
