On azeotropic distillation
Thread Content
This post was last edited by yuyiyummy on 2010-6-2 23:06. I’m a bit confused regarding azeotropic distillation. For example, when distilling ethanol-water, once the ethanol concentration reaches 93%, it’s no longer possible to increase it further. Generally, a small amount of benzene is added to disrupt the azeotropic system. But if the ethanol concentration in the feed material is already 95%, then isn’t it possible to increase the concentration without adding benzene?

Just pass through the azeotrope; after that, it works like ordinary distillation. One product is the compound with a low boiling point and the azeotrope, while the other product is the compound with a high boiling point and the azeotrope. As for the azeotropes, they can be decomposed further
