If it's not listed in the MSDS, it's likely a denatured with a trace of <a href="http://en.wikipedia.org/wiki/Denatonium" target="_blank">denatonium benzoate</a> <img src="../scipics/_wiki.png" />.

I thought so, either that or a pyridine. I remember finding a thread somewhere else on this specific brand of denatured alcohol, but I can't seem to find it. Seeing as the EtOH which was first distilled over CaO didn't produce the black tar, what ever the denaturant was, it must have been destroyed by it. (or at least reduced to something with a high boiling point).

Where can you get a fractionating column with actual plates, such as the one seem in the video? Is a packed column more efficient?

Question( if I may): would PTFE tubing be acceptable to feed the ethanol under the surface& into the rxn mixture? I am pretty sure that the temperatures aren't too harsh for it but with the boiling ethanol& sulfuric acid mixture I wanted to ask. Finding an a glass adapter to do so is becoming harder and harder.

Can we add "full" quantities of EtOH and H2SO4 ALL AT ONCE and obtain ether?
I tried right now and i obtained some liquid with the smell of EtSO4,maybe that's actually smell of ether,but when i mixed with water there were no layers...I don't know what's going on...And my oil in the oilbath was little bit overheated,and after some time it was boiling but the flask was cloudy maybe ethylene formed couse oil was more than 180C...
Anyway....I'm litle bit narcotized by fumes..

When i collected that first liquid i was somewhere else,and then writting this message,when i turned back to see,this is what i found... :D
Carbonized? Inside flask is pure carbon or something else but it looks like when you mix sulfuric acid and sugar...
