ABSTRACT:
Isopropanol and n-propanol cannot be completely separated from water by conventional distillation or rectification because of the minimum boiling azeotrope. Isopropanol and n-propanol can be readily separated from water by using azeotropic or extractive distillation. Typical examples of effective agents are: for isopropanol by azeotropic distillation, vinyl n-butyl ether; by extractive distillation, polyethylene glycol; for n-propanol by azeotropic distillation, amyl formate; by extractive distillation, n-butyl acetate.
