Well he's some results of a test I ran in my breaks today .
Measured 10mls of each into an evaporation basin and when the lowest one still had a measurable amount , I measured then to see how much each had evaporated .
The first time I did it , I had them sitting in the Fume hood but not running .Unfortunately someone mentioned the smell so I had to turn it on but it very quickly evaporated them ...LOL...good to see it worked .
So I did it again later when no one was around so it would evaporate more naturally .
This could account for the variations between the two tests . I was going to run it a third time but ran out of time .
So the interesting things to me are that just because boiling points are close , does not mean that evaporation rates are close . looking at the Ethyl acetate and Ethanol , it is apparant that the Ethyl acetate is evaporation at a quicker rate than the Ethanol despite the 1 degC difference in boil point.
Also notice that the Butal-1-ol has a boil point of 117 deg but evaporated more than the water . Butan-2-ol ( 2-Butanol) Boils at 1degC less than water but it is evaporating at a much quicker rate .
Acetone BP 56 degC
Methyl Acetate BP 57.1 degC
Methanol BP 64.7 degC
Ethyl Acetate BP 77.1 degC
Ethanol BP 78.3 degC
2-Propanol BP 82.6 degC
1-Propanol BP 97 degC
2-Butanol BP 99 degC
Water BP 100 degC
1-Butanol BP 117.7 dgC
The pencil graph is the first run , the red graphs was the second run
Note that these are testing the evaporation of pure substances but how they evaporate when mixed together is another story I can imagine .
Anyway something to mull over .
Oh and by the way IMHO Aussie fingernail polish clearly smells like Ethyl Acetate , 1-Butanol smells very much like the concentrated Tails smell you get in the packing of a reflux still ...and Methanol has no smell that I can percieve . 2-Propanol smells like Isopropal or Rubbing alcohol . The others have unique smells but hard to explain .....I don't do well explaining that kind of stuff
