Separation of formic acid from acetic acid by azeotropic distillation |
摘要 |
Formic acid difficult to separate from acetic acid by conventional distillation or rectification because of the close proximity of their boiling points. Formic acid can be readily separated from acetic acid by using azeotropic distillation. Effective agents are cyclopentane and tetrachloroethylene.
