Ice-cream Posted April 8, 2005 Share Posted April 8, 2005 Does any1 know whether ethanol is an water-immiscible organic solvent? Link to comment Share on other sites More sharing options...
Skye Posted April 8, 2005 Share Posted April 8, 2005 Ethanol is what makes alcoholic beverages alcoholic. Link to comment Share on other sites More sharing options...
jdurg Posted April 8, 2005 Share Posted April 8, 2005 If ethanol didn't mix with water, there'd be a lot of unhappy, yet healthier, people in this world. Link to comment Share on other sites More sharing options...
dan19_83 Posted April 8, 2005 Share Posted April 8, 2005 All hail the mighty man or woman who was smart enough to mix ethanol with water and then think in his head: 'hmmm, maybe i'll drink thisand see what happens' he had a good few hours after that i would think!

ed84c Posted April 8, 2005 Share Posted April 8, 2005 Chemical Formula C2H5OH, so yes it is organic Link to comment Share on other sites More sharing options...

That person had some mighty big cajones to say 'Hey, look at this frothy, bubbly mess that arised when the yeast fell onto our hops and barely this past winter. I'm going to go drink that moldy froth!' Link to comment Share on other sites More sharing options...
YT2095 Posted April 8, 2005 Share Posted April 8, 2005 I thought that occured upon seeing Birds that ate the soggy grain acting perculiarly? hence stone age man used to bags made of HOP vines full of soggy Barley into Nightclubs, in hopes of procurring a female without a sense of smell Link to comment Share on other sites More sharing options...
Fortuna Posted April 8, 2005 Share Posted April 8, 2005 No, it is not immiscible. Water and EtOH are very miscible. In fact it will form an azeotrope. (95/5 EtOH/H2O). When doing a fractional distillation on a 50/50 EtOH/H2O solution, you will end up with the azeotrope (95/5) and water, even with your best packed column. Getting the EtOH to 99+% is possible (however, obviously not using FD). Voegel gives a procedure for producing dry EtOH in his "Solvent & reagents" section.

Skye Posted April 9, 2005 Share Posted April 9, 2005 Probably not, considering Vogel is misspelled Link to comment Share on other sites More sharing options...
Fortuna Posted April 14, 2005 Share Posted April 14, 2005 ed84c, Why on earth would you think that such a commonly known and basic piece of information about one of the most common solvents has to be copied from a website ? This is elementary stuff No, I have a copy of Vogel's (better?) 3rd edition of Practical organic chemistry. And no, I've never seen that procedure reproduced on a website. Hey, its my job to do this kind of stuff. And it pays very well too ! And For the record, you will never hear me claim to be a good english speller. Also, I doubt that Vogel would give the proportions in v/v %, or use an offhand term like "packed column" to refer to a glass filled distillation column.
