ABSTRACT:
Acetic acid cannot be easily removed from acetic acid--water mixtures by distillation because of the closeness of their boiling points and the deviation from ideal solution behavior. Acetic acid can be readily removed from mixtures containing it and water by using extractive distillation in which the extractive distillation agent is a mono carboxylic acid, either singly or admixed with high boiling organic compounds. Typical examples of effective agents are pelargonic acid; heptanoic acid and isophorone; neodecanoic acid, acetophenone and nitrobenzene.
