ABSTRACT:
2-Butanone is difficult to separate from isopropanol by conventional distillation or rectification because of the proximity of their boiling points. 2-Butanone can be readily separated from isopropanol by azeotropic distillation. Effective agents are 3-methyl pentane, methyl t-amyl ether and acetonitrile.
