Elite Engineer Posted April 30, 2015 Share Posted April 30, 2015 (edited) So I read about the various nonpolar aromatics present in whiskey and decided I would try to separate them out (I was bored). I measured 2 mL of Jefferson creek whiskey and 3 mL of xylene into a vial, mixed and then centrifuged for 5 minutes. When I looked at the vial, there was the organic phase on top, relatively clear and then below that was a solid white precipitate, with a color exactly like egg whites. Below the white precipitate was the aqueous phase, consisting of a brown, clear liquid from the whiskey. When I pipitetted the white liquid out and mixed it with xylene, I found it was NOT miscible with the xylene and was therefore hydrophilic. I really have no idea what this was, any ideas? p.s.- I currently do not have a camera nor smart phone so i can post a picture. If I do in the near future I will! ~ee Edited April 30, 2015 by Elite Engineer Link to comment Share on other sites More sharing options...
John Cuthber Posted April 30, 2015 Share Posted April 30, 2015 Sounds like an emulsion to me. Link to comment Share on other sites More sharing options...

John Cuthber Posted April 30, 2015 Share Posted April 30, 2015 If you have a look here you can see what the analysis of whiskey shows you about how complicated it is. http://www.chromatographyonline.com/advances-ageing-chemistry-distilled-spirits-matured-oak-barrels-0?id=&sk=&date=&%0A%09%09%09&pageID=2 Why would you think that none of those compounds is amphiphilic?
