Talk:Ethanol purification

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?

 * This is not the same and this is the point. Mixtures distilled in these both cases (last stage) contains MORE ethanol than azeotrope, so ethanol boils in higher temperature than azeotrope. -Yyy (talk) 16:03, 8 November 2008 (UTC)

I don't feel this page should be merged because other chemical extraction/purification methods have their own page. Not to mention ethanol alcohol is purified with benzene, although it should evaporate before ethanol considering it's low melting point. — Preceding unsigned comment added by 99.38.162.247 (talk) 19:27, 24 June 2011 (UTC)

I also disagree with the merge. 98.249.9.252 (talk) 21:12, 27 January 2012 (UTC)

Where are the citations? I checked the only reference, there is no mention of molecular sieves. — Preceding unsigned comment added by 128.230.232.110 (talk) 05:42, 6 May 2012 (UTC)

Proposed merger with Ethanol
This topic has been discussed previously. I think that the preparation, description, and purification of a compound all belong together. But comments are welcome.--Smokefoot (talk) 18:21, 5 December 2012 (UTC)
