Talk:Still

From Wikipedia, the free encyclopedia

Honestly now, either change it to a disambiguation page, or leave it as it is. There are more than one album with the name "Still" and just because you enjoy one of them doesn't mean that everyone is searching for it. Ugh, I even registered an account just to change that back.

[edit] French version

There are a bunch of good pictures there, which should be moved here. Fuzzform (talk) 04:28, 17 March 2008 (UTC)

[edit] Dry ice condenser

Would it be possible to add a dry ice condenser to a reflux ? See http://homedistiller.org/photos-ns.htm and http://www.sigmaaldrich.com/Area_of_Interest/Equipment_Supplies__Books/Glassware_Catalog/Evaporators__Condensers.html

Look into it and perhaps include in article. Thanks 81.246.185.121 (talk) 09:12, 29 May 2008 (UTC)

Yes, as long as the boiling material does not freeze (thus stick) on the condenser. Often a cold finger can serve this purpose. For example you can reflux dimethyl ether with a dry ice condenser. Room temperature (or a bath of ice-water) is sufficient to cause the liquid to boil (i.e. boiling point of about -20°C) and dry ice will condense DME it to a liquid without freezing it (i.e. DME has a melting point about -140°C which is below -78°C of dry ice). I think it is getting a bit left-field to be in the main article?? Anyone disagree? -- Quantockgoblin (talk)

I've just checked ethanol has a melting point of −114.3 °C, and so a dry ice condenser could be used in that case to set up a reflux. However, a dry ice condenser is only really of any practical use (in a reflux system) if a cooled water condenser can not be used (i.e. the boiling material boils below about 5°C, or if the boiling liquid has a bad smell). -- Quantockgoblin (talk) 13:17, 29 May 2008 (UTC)
