ABSTRACT:
Pyridine cannot be completely separated from water by conventional distillation or rectification because of the minimum boiling azeotrope. Pyridine can be readily separated from water by using azeotropic or extractive distillation. Typical examples of effective agents are: by azeotropic distillation, methyl isoamyl ketone and propylene glycol dimethyl ether; by extractive distillation, isophorone and sulfolane.
