ABSTRACT:
Acetone cannot be completely removed from acetone-methanol mixtures by distillation because of the presence of the minimum boiling azeotrope. Acetone can be readily separated from methanol by using extractive distillation in which the extractive agent is dimethylformamide, either alone or admixed with other compounds. Typical examples of effective agents are: dimethylformamide; dimethylformamide and diethylene glycol; dimethyl formamide, glycerine and propylene glycol.
