Talk:Ethanol purification

From Wikipedia, the free encyclopedia

How does adding benzene or using vacuum distillation cause the anhydrous ethanol to come out on the bottoms of a column? Ethanol normally comes off the top of a column being that it boils at a lower point than water, wouldn't this been the same with entrainers or under vacuum conditions?
