It appears that the picture of the chemical formula is broken, since it only shows 3 bonds and one Oxygen atom for me, and the chemical formula is much more complex.
The image that is displayed is the skeletal formula. It only shows the bonds between Carbon atoms, as well as other atoms or functional groups, with the exception of hydrogen. It is to show the basic shape of the molecule. Wherever there is a vertex without a label, it is a carbon atom.
DrBob, I'm interested in the cheap method of manufacture, where did you get the information on Weizmann?

Acetone and other solvents are uses in purification of hundred of compounds, because diferent solvents are diferent partition coeficient for each substance. One simplest example: a solution of iodine and water can be almost completely separed adding toluene and mixing. Toluene dissolves most iodine and much less remain in water, and toluene is separed as a other layer. Most alkaloids (cocaine, cafeine, heroin, etc) are extrated from plants with solvent and purified with sequential solvent extrations of remaining solutions.
I don't know which one is correct, but according to pubchem ( http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=180&loc=ec_rcs), the IUPAC name is propan-2-one, not propanone. Does anyone know which one is true? —Preceding unsigned comment added by 180.246.229.22 ( talk) 09:06, 12 September 2010 (UTC)
Hey, I don't ever edit Wikipedia so sorry about the formatting here. But that's why I edited the talk page, not the main one :)
The entire section on "medical uses" is pretty sketchy. Note that "defatting (medical)" on this encyclopedia, while a stub, is better cited and notes defatting as a thing to be avoided.
And for those of us who have worked with acetone, you definitely DON'T want your skin all dried out using it!
The whole uncited "ancient Egypt" thing sounds like some kind of unfounded alternative medicine BS, and the "Prior to chemexfoliation, the skin should be cleaned properly and excess fat removed" is unencyclopedic.
Beyond the "Acetone is used in a variety of general medical and cosmetic applications and is also listed as a component in food additives and food packaging." there is little of value in the entire section. At the least, it should probably be merged with another section (Niche uses maybe) and more likely is appropriate for removal.
If (as I see on this talk page) acetone as a lab equipment cleaner (something that legitimately does happen, all the time - as could be cited from any undergraduate OChem lab manual) is not appropriate for the page, then certainly its use as a medical defatter isn't.
There's clearly some disconnect between that section and the rest of the article anyway, since the ketogenic diet referred to elsewhere in the article is obviously a medical use.
Section "Uses" -> "Laboratory" -> "Chromatography"
This subsection does not contain anything related to acetone at all. I suggest to remove this section. 213.232.244.41 ( talk) 08:21, 22 March 2023 (UTC)
