Acetone
Found 1l bottle of Acetone in a shop today.
Distilling it seems to show that it's 100% Acetone.
Miracles do happen !
EDIT: No they don't

Isn't the acetone found at hardware stores pure acetone as well?

There are a number of processes to produce acetone. The type of contaminants observed will tell you which process was used. Needless to say, there
are anyways some of these contaminants in even the purest of samples. Additionally many of the consumer samples of acetone have been deliberately
bittered with either denatonium benzoate or denatonium saccharide to prevent accidental ingestion. While generally not listed on container it is
listed on the MSDS from the company.

I spoke too soon.
The Acetone was coming over at exactly 56 degrees +/- 0.1 then it started rising, so i swapped receiver bottles.
Now we got brown stuff forming in the RBF
A small amount, and this is in a water bath, but definitely brown

Slightly more challenging would be to distil acetone from nail polish remover (caution: some NPRs don't contain acetone anymore!)

Haha, yeah, I found some nail polish remover (before I learned to be suspicious of what labels claim) that was called "100% Pure Acetone." Upon
reading the ingredients, it said "Acetone, Water, Fragrance, Bittering Agent." Hmm… 100% Pure indeed...

Remember technically 99.5% = 100%, the companies love to play games with the numbers like that...

Sorry to drift off but has anyone extracted denatonium benzoate this way?
Good eyes

Distilling a NPR once (I was desperate for acetone, I would normally buy it) I did obtain a solid residue in the boiler and remember thinking:
"denatonium benzoate?" (it was listed as an ingredient)
The quantities in there are really small though (I think). And there's other stuff too...

Yeah, I'd assume there'd be milligram amounts. Also, I'm unable to look up this abbreviation NPR, what does it mean?
[EDIT] Oh wait nevermind...

NPR = Nail Polish Remover.
Nothing to do with Polish people removing nails.
denatonium benzoate (judging from the distillation flask) is present as a tiny tiny amount (if that is what it was).
I distilled a litre of acetone, and i estimate the Brown Stuff to be around 1 ml.
There may well be Other Thongs in there, so to make sure, i discarded any distillate < 55.6 C or > 56.3 C, (vapor temperature) of which there
was about 200 ml, =20%.

Nope, that would be Polish Nail Remover

Did your starting product state it contained denatonium benzoate? Don't confuse NPR with commercial acetone, the former is quite heavily
'formulated'.

The product label stated very little, apart from saying' Acetona' in big letters.
I followed up an EC code on the label, but that led nowhere apart from Safety data, such as do not distill ...
As there was no info, i chose to dump any distillate that was more than 0.2 C from the 56 C BP of acetone, losing about a quarter of a litre in the
process.
What i ended up with is something that boils at 56 C, hopefully acetone.

If you haven't seen this (http://www.chromatographyonline.com/lcgc/Article/Investigati...), it does make for interesting reading.

When I distilled nail polish remover, I was left with an orange solution in the distilling flask. This was done at 1 atm, with pretty standard
conditions (high heat, adequate cooling). Not really sure what it was, but I just thought I'd weigh in.

I believe that you are seeing some oxidized phenol remaining in the pot.

The remaining stuff is more likely aldol condensation products from acetone, plus the crud that was in it to start. I don't know where "oxidized
phenol" would come from in acetone or even what that would be unless you are starting with a hydroquinone.

I believe that phenol is a fairly common impurity in most acetone samples.

"In the cumene process benzene is alkylated with propene resulting in cumene (isopropylbenzene), which is subsequently oxidized to give phenol and
acetone."

one could decide to take several litres of denatured spirits and distill most of it away, then let the more concentrated denatonium benzoate solution
boil off..
dont recall hearing anything about they add other stuff to denatured alcohol, as in solids.. i have heard about MEK and IPA and ofcourse methanol
