ABSTRACT:
Heptane cannot be separated from vinyl acetate by conventional distillation or rectification because of the minimum boiling azeotrope. Heptane can be readily separated from vinyl acetate by using azeotropic distillation. Typical examples of effective agents are methyl acetate, ethanol, ethyl formate or t-amyl methyl ether.
