From Talk:Propanone

I will be moving this page back soon to its original location as acetone. Wikipedia policy states that "use the style of the International Union of Pure and Applied Chemistry (IUPAC) for chemical names wherever possible, except in article titles, where the common name should be used if different, followed by mention of the IUPAC name." Acetone is such a common chemical and it is nearly always referred to by that name, even in chemical catalogues. IUPAC recognises this, and allows use of acetone as a name].

A Google search for acetone generates 1,100,000 hits. Propanone generates 41,000.

I will move the page back tomorrow once people have had a chance to comment. Walkerma 20:26, 12 May 2005 (UTC)

Most of the history for this page is to be found under the acetone page. No evidence was presented before the edit-move to support the claim that "Acetone is no longer the officially recognised name of propanone." Walkerma 04:49, 14 May 2005 (UTC)

I agree, acetone is the correct title. Just one comment, this appears to have been a cut-and-paste move with subsequent edits at this name, so whatever you do you will lose some page history. -- Securiger 13:49, 15 May 2005 (UTC)

Section removed

I have removed the section "Use as a cleaning solvent" from the article because I think it has minimal significance, it is written in an unencyclopedic style, and it comes across more as instructions on how to clean lab glassware than as a description of acetone itself:

Due to the relatively polar properties of acetone and its high rate of vaporization, it has been used in many university labs as a cleanser for substances in test tubes after working with all manner of organic substances (e.g. cyclohexane, cyclohexene). Acetone is squirted directly from a bottle containing the substance onto the glassware and is (usually) drained into a specially marked organic waste bucket. Acetone is particularly useful because it is inexpensive, is moderately polar allowing it to dissolve a wide range of organic substances, and evaporates quickly. However, care should be used when cleaning test tubes with acetone as acetone is readily absorbed through vinyl or latex gloves and will come in contact with skin where it is absorbed into the skin. If an excessive amount of acetone is splashed onto gloves, remove gloves immediately and wash hands with water before donning a new pair of gloves. Due to its high volatility, acetone evaporates quickly. A quick way of drying wet glassware is to rinse the inside surfaces of the freshly washed item with acetone. Since acetone is miscible with water, any water present will be removed as the acetone is poured out. The remaining film of acetone (containing traces of water) will evaporate quickly on the bench or inside an oven. Also, if you want to speed up the evaporation of the acetone, you can blow the glassware with compressed air underneath a fume hood.

In my opinion, the article could use some expansion in terms of the use of acetone as a solvent and cleaner, and perhaps portions of this section can be used for that purpose. --Ed (Edgar181) 12:47, 6 February 2007 (UTC)

The exceedingly common use fo acetone as a cleaning agent in laboratories should definitely be mentioned. Sewercockroach 22:03, 12 July 2007 (UTC)

Azeoptropic Information

Azeotropic data should be either mentioned on the Acetone main page or the data page. Acetone doesn't form azeotropes with dichloromethane or water, but it does with hexane(s) according to http://www.solvent--recycling.com/azeotrope_1.html. Sewercockroach 22:03, 12 July 2007 (UTC)

"Safety" section is useless.

What are "incompatibilies," chemically speaking? This section needs expansion/explanation. —The preceding unsigned comment was added by 71.100.182.201 (talk) 11:02, August 22, 2007 (UTC)

User 71.100.182.201: Regarding "incompatibilities". Acetone is a relatively inert chemical and an excellent organic solvent; for this reason, it is used to clean organic laboratory equipment. However, one should avoid using acetone if said glassware is contaminated with bromine, as the resulting reaction will yield bromoacetone gas, a lachrymatory substance. (References: Wikipedia; Macroscale and Microscale Organic Experiments ). Murphy2010 (talk) 05:49, 10 February 2008 (UTC)

Context?

"Acetone is listed as a Table II precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances."

Anyone have information on the specific reason it is listed as a precursor? Are there any particular drugs that people use acetone in making? --Head of the Caligula Appreciation Society 09:36, July 19, 2005 (UTC)

This statement is near the end of the beginning introduction:

Acetone is listed as a Table II precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances[1]

It would be useful not to have this just be dropped in there without explanation and context. Why is it a narcotic / psychotropic substance, who are the people that abuse it, what are its effect on humans, how does this (solvant abuse?) affect the nervous system to produce the 'high'? If it is just solvant abuse then a link there would be good but I am not sure in what context this chemical is 'illicit' but that is my guess.--ShaunMacPherson 12:59, 12 August 2005 (UTC)

I think the key word here is precursor. It isn't a "drug" in itself, it is simply used to make drugs. Of course most things can! You can still buy acetone at many hardware stores in the US (I think!), so I don't think it's considered a serious problem. I tried following the links, and although I found what the convention is, I found no link that tells me the meaning of the phrase "Table II precursor." I can only guess that if you are a Bolivian farmer who has 10 tonnes of acetone in the barn you can now get arrested for it.
Personally I hate having this awkward phrase in the opening section of the article (and several other articles), but I left it in because I assumed it was of great topical interest. I had also noticed the slant of interest in Wikipedia- many psychedelic substances have had full-length articles for a long time, while major commodity chemicals like sodium sulfate had nothing at all! However in light of the fact that
  • It spoils the flow of the article, and
  • If one clicks on the given links to find out what the phrase means, you come to a dead link. (Since it is an incomprehensible phrase by itself, it probably shouldn't be there at all.)
Therefore I'm moving this phrase down to "Uses" (it is NOT a fundamental property or use of acetone), and linking to a definition of precursor. If you have any other suggestions, please give them here. Walkerma 15:10, 12 August 2005 (UTC)
Update – I removed the confusing phrase from the article altogether. Reasons are twofold:
  • The definition of what "Table II Precursor" means is unclear. I requested a definition here, but after several months there has been no response.
  • Until the first point is clarified I can't be sure, but as I understand it acetone is NOT an illicit drug like heroin (it's available in most hardware stores in the US over the counter), merely that it can be used (probably as a solvent) for making a major drug. That is probably true of most major organic solvents, and it is not an unusual feature of acetone. Until some explanation is provided of how acetone in particular needs this information, I think it is merely confusing, alarmist and unnecessary. Walkerma 16:58, 1 November 2005 (UTC)
    • Indeed, acetone is listed in table II of the said Convention, as a "chemical frequently used in the illicit manufacture of narcotic drugs" and not as a precursor per se. This may lead to regulatory restictions on the sale of large quantities of acetone in various jurisdictions, but for the time being I know of none in the jurisdiction in which I am resident (France, which controls the supply of various table I substances including, for example, acetic anhydride). I support the removal of the information from the article until such time as we can provide a balanced overview of the regulations concerning the supply of chemicals in the major English-speaking countries.

Amount produced

In the first paragraph of this article (at the very top of the page) it says: "More than 3 million tonnes are produced annually, mainly as a precursor to polymers.[2]" Is this amount for worldwide, or is it for the United States of America? This should be clarified. If it is the latter, for the USA, one should be reminded that this is "en.wikipedia.org", not "us.wikipedia.org"... A lot of English language written material on the web is about the US, without this being pointed out, which IMHO writers should change as this is the Internet, not "America Online". After all, English is used daily in a lot of countries around the world, from Asia to Africa, Europe and America... Hope somebody can check the article referred to[2] and clarify the text! Thanks!

Fuel additive

(* warning the following section is hearsay *)

In the last few months, there has been some discussion of acetone as an additive in gasoline and diesel to improve performance of those fuels [1]. However, there doesn't appear to be very much scientifically-gathered data out there to support this idea as of yet. In the past, acetone has been a well-known addition to racing fuel, though the recent discussions talk about using it in much lower quantities—fractions of one percent rather than, say, 20% or higher mixes. It's not really clear how the mixing of fuel to have 0.15% or 0.25% acetone can change much, other than primarily cleaning built-up residues out of an engine, unless it acts as a catalyst or something. (Note: evidence suggests the acetone acts as a mechanism to reduce surface tension of fuels. The result is a cleaner, more efficient burn [User:JKS]) Anyway, it's interesting, and I considered adding some notes to this article, but I decided against it for now since the current evidence is so limited. —Mulad (talk) June 29, 2005 00:26 (UTC)

Mulad- I'm not a fuel scientist though I am an organic chemist, so I have acetone instead of blood running through my veins! The science on the website you cite seems suspect to me- if you could change vapour pressure like that you could lower the boiling point of water in a similar way, and I don't think you can. I'd guess that acetone helps dissolve traces of water that might otherwise cause the engine to run less well. Pure gasoline or diesel can only dissolve a tiny amount of water, but rather more if acetone is added- there are commercial additives for gasoline that work the same way. That's my guess. Please let us know if some scientific studies are done on this. Walkerma 29 June 2005 05:12 (UTC)

Walkerma- if you can lower the surface tension of a liquid, it will vaporize more readily. And one way to reduce the molecular cohesion of a substance is to introduce a surfricant. So, the question is, is acetone really a sufricant? Brontus

From what I'm gathering, the common recommendation is about 3-5 oz per 10 Gallons of fuel. Found this on Fark, but I'm not trusting it enough to put my life to it: http://peswiki.com/index.php/Directory:Acetone_as_a_Fuel_Additive -- also, some of the links they're showing are dead and forward to unnecessary sites.. so don't bother with those. I did find that in general an interesting, if not accurate read on the subject of using acetone for fuel additives, however. Rickz0rz September 7, 2005 06:17 (UTC)

GS- I've run experiments in my Ford Expedition. I went from 12-12.5 MPG to 15.25MPG. The primary reason for individuals NOT finding success with Acetone in fuel has been the overuse of it. the above recommendation of 3-5 oz per 10 gallons likely would cause a decrease in fuel economy for many vehicles. If you're interested in trying this, start at 1oz and work your way up slowly. Also, be sure to use 100% acetone. My vehicle received the 18%+ efficiency gain with only 1.25 oz per 10 gallons.


A CLOSER LOOK:

In a popular article quoted above, Mr. Louis Lapointe states that greater combustion efficiency is achieved through the lowering of surface tension of the fuel by the addition of acetone (a ketone) or methyl ethyl ketone resulting in a significant increase in fuel economy and lower exhaust emissions. Many aftermarket fuel additive companies have claimed significant mileage increases through better combustion as well. Both gasoline and diesel, comprised of non-polar hydrocarbons, already exhibit very low surface tension. C8, for example has a surface tension of 21.80 dyne-cm compared to water at 72 dyne-cm at 25 degrees centigrade. As a liquid is heated there is a corresponding decrease in surface tension up to the point at which the liquid vaporizes. In a warm, well running engine, the fuel is in vapor phase during the combustion cycle leaving surface tension no part to play as surface tension pertains to liquids, not gasses. During the compression stroke of a direct injection diesel engine, the temperature of the intake air is typically in excess of 1000°F (from compression) before the fuel is injected at more than 20,000 psi while, in gasoline engines, the fuel is vaporized in the ports before entering the cylinders. Needless to say, during the ignition process, the greatly increasing temperatures and resulting turbulence vaporize any fuel that may still be in atomized form. The bulk of the vaporized hydrocarbons that do not oxidize are generally in regions of the cylinder which tend to remain at temperatures too low to support combustion and in areas where the mixture is too lean for the vapor to ignite; an example would be the space between the piston and cylinder wall just above the top compression ring. This amount of unburned fuel, though, is quite small, ranging from 1% to 2% in modern gas and diesel engines. Those that would say that fuel is still burning after leaving the cylinder need to remember that exhaust temperatures measured in the exhaust manifold run between 1000F to 1400F while running at full power when the exhaust is at it’s hottest. These temperatures are far below a gasoline or diesel flame (>3500). Combustion efficiency is affected to a far greater extent by the physics inherent in engine design than by chemistry.

Quoting Chevron Oil: “Combustion catalysts may be the most vigorously promoted diesel fuel aftermarket additive. However, the Southwest Research Institute, under the auspices of the U.S. Transportation Research Board, ran back-to-back tests of fuels with and without a variety of combustion catalysts. These tests showed that a catalyst usually made "almost no change in either fuel economy or exhaust soot levels." While some combustion catalysts can reduce emissions, it is not surprising that they don't have a measurable impact on fuel economy. To be effective in improving fuel economy, a catalyst must cause the engine to burn fuel more completely. But there is not much room for improvement. With unadditized fuel, diesel engine combustion efficiency is typically greater than 98%. Ongoing design improvements to reduce emissions are likely to make diesel engines even more efficient.” http://www.chevron.com/products/prodserv/fuels/bulletin/diesel/L1_toc_rf.htm]

“Incomplete burning of fuel is insignificant in modern cars. Fuel combustion today typically exceeds 98 percent.” John Heywood, professor of mechanical engineering at MIT and an authority on internal-combustion engines.

Using the above figures, if the addition of acetone / methyl ethyl ketone (or any other additive) to the fuel was to produce even 100% combustion, with zero unburned hydrocarbon emissions (which it will not), we would only realize an additional 1% - 2% increase in thermal energy. The diesel engine is about 50% thermally efficient, (gasoline 30%) with 50% of the energy of the fuel available to turn the engine while the other 50% is being shed primarily as heat from the radiator and exhaust. This would leave an increase of .5% to 1% of usable energy that could be applied to overcoming friction in transmission, wheels, radiator fan, etc. and increasing mileage. Assuming our mileage averaged 18mpg, we would realize 18mpg + .5% to 1% = 18.09mpg – 18.18mpg in theory with the practical amount a fraction of that. Assuming acetone addition would provide 100% combustion efficiency, (and there is no scientific evidence to support the assumption that it increases efficiency at all), and not factoring in loss to friction in drive train, etc., the resultant theoretical increase of far less than 0.1mpg would be so negligible so as not to be measurable. Statements such as “Most fuel molecules are sluggish with respect to their natural frequency. Acetone and/or methyl ethyl ketone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension” are pure pseudoscience and are not found in the nomenclature of chemistry. As a recent study by Cummins Diesel demonstrates, fuel mileage can be affected up to 30% by driving habits alone. How many are expecting to see an increase in mileage after the addition of acetone or methyl ethyl ketone? How much is this expectation affecting driving habits? And how many people are going to report it if they saw no increase and how many will become discouraged and just "forget the whole thing"? How do we account for the people that report a decrease?


(Third party) More science must be done before either position can be verified as the correct one. —Preceding unsigned comment added by 24.10.131.61 (talk) 00:34, 10 September 2010 (UTC)

Fascinating. I am not a chemist, but my first immediate reaction was that acetone, being a very potent, very aggressive nonpolar solvent, could potentially damage polymer gaskets and seals inside an internal combustion engine, especially once it reaches operating temperatures of 100 degrees C. or higher, if the polymers were not chosen specifically with acetone resistance in mind. I had been accustomed to thinking in terms of acetone as a fuel additive with the purposes of absorbing moisture and removing deposits from fuel injectors, etc., not as a fuel itself.

Otherwise--well, what of the old Weizmann ABE (acetone-butanol-ethanol) anaerobic fermentation process? It produces acetone, butanol, and ethanol in an approximate ratio of 30%-60%-10% by weight. Butanol is already known to be an excellent fuel for internal combustion engines. Could the ABE fermentation mix, just as it comes out of the vats after purification, be a useful motor fuel? How much redesign would the engines require? In these days of "peak oil" and growing worldwide demand, it seems to me that this is worth investigating at the very least. — Preceding unsigned comment added by 69.41.40.24 (talk) 19:26, 25 June 2012 (UTC)

"Solvent Use" confusion

I was reading through the article and the "Solvent Use" section confused me. It said "Acetone is a good solvent for most plastics and synthetic fibers including those used in laboratory bottles made of polystyrene, polycarbonate and some types of polypropylene." Does that mean that it dissolves laboratory bottles? If so, that's false since there are several wash bottles in the lab that I use that have acetone in them. — Preceding unsigned comment added by AlejoM (talk • contribs) 18:43, 16 October 2011 (UTC)

Nalgene ref is bad and sentence is misleading. Not sure that "good" should be applied regarding polycarbonate, and definitely not for polypropylene. The fact that a material is swelled and hence not recommended for storing (depending on mol. wt) does not mean its a good solvent.

Cleaning

Acetone seems to be good for cleaning glass and removing sticky adhesives from same. I wonder how good it is for thinning a touch up primer that is now too thick.. I do not know if acetone was originally an ingredient.

Acetone is a solvent with a high vapour pressure and low boiling point. If you add it to your primer, it will definately make it thinner and will likely disperse evenly, as it is miscible with every other common solvent. However you may get streaking when you try to apply your paint, as you might get a chromatographic effect when you apply it to paper -- it will take some of the ingredients which dissolve well in acetone but do not adsorb well to your surface and carry them farther than components of your primer which either adsorb well to the surface or are not very soluble themselves in acetone. Try a small amount first, then try a small patch, to see if you get the ratio right and if it affects performance.

What about chemical properties?

This compound has a rich chemistry, and yet there is not even a "Chemistry" section in the article. --Jorge Stolfi (talk) 21:57, 7 January 2020 (UTC)

Name discussion

Why was it named "acetone"? Acetone and propanone sounds like different compounds. Acetone has 3 carbons but it has a name like it should have 2. As i heard from somewhere it was previously "aketon" and meant "derived from acetic acid". Why wasn't it changed to propanone? — Preceding unsigned comment added by LeticiaLL (talk • contribs) 10:00, 19 January 2020 (UTC) I found it was meant "daughter of vinegar". — Preceding unsigned comment added by LeticiaLL (talk • contribs) 10:21, 19 January 2020 (UTC)

Medical Disinfectant?

There's this video where a guy on a fishing boat named Chip Salinger got bit in the hand by a mako shark and the only things they had to treat his bite wounds were acetone and duct tape. Surprisingly, his hand healed normally after the incident. --Arima (talk) 00:20, 8 November 2009 (UTC)

Depends. I would not use it, we have better materials today. This study from 1956 says it did help (on students hands - OMG!), but Ethanol was better. Don't try it at home. Use the right products and procedures not just raw-chemicals such as acetone which have different backgrounds and applications. Check virucides for deeper info.

Pollution

Main article reads "it is considered by the EU as a contributor to environmental pollution.[citation needed]" - checking EU ECHA, reads "Due to the ready biodegradability of acetone and its low log Kow (-0.24) the substance is not classified as dangerous/hazardous for the environment according to Directive 67/548/EEC and according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):"; I don't conclude with this short analysis it is not a pollutant, this is not my job, but it was asking for citation and this is one source. I'm not changing the main article, I have other topics. KR 17387349L8764 (talk) 12:44, 26 May 2021 (UTC)

http://webbook.nist.gov down for maintenance

I got this message: "We're sorry, but webbook.nist.gov is unavailable this weekend, Saturday and Sunday April 14-15 2018, due to infrastructure maintenance. We expect it to be available by Monday, 07:30 EDT, April 16, 2018" accessing http://webbook.nist.gov. It was still Friday in my time zone.User-duck (talk) 07:04, 14 April 2018 (UTC)

It's working again, 2021... KR  Done 17387349L8764 (talk) 07:44, 27 May 2021 (UTC)

odor smell taste

Please add information about the odor / smell / taste of acetone.-96.237.79.6 (talk) 23:55, 27 September 2010 (UTC)

Done. --Jorge Stolfi (talk) 21:53, 7 January 2020 (UTC)
Hi, "Pungent, irritating, floral, cucumber like" is without reference. It ready "fruity odor" in this reference. KR 17387349L8764 (talk) 08:00, 27 May 2021 (UTC)

Farming

I saw some news articles recently about Acetone being used as a substitute for sunlight for growing crops. Can we add something about it? I cannot find the article but someone here might be able to find it again Immanuelle 💗 (please tag me) 21:03, 6 July 2022 (UTC)

Infobox Images

Shouldn't the infobox contain, for example, File:Aceton.svg instead of the skeletal formula? When I go to a chemical's page like this, I expect one of the first things I see to be both the written formula and the full 2D layout (not sure what the correct word is in chemistry).
