Talk:1,1,1-Trichloroethane

Toxicity

I am concerned that your article indicates that trichloroethane is "relatively non-toxic" although studies confirm that inhalation triggers a syndrome known as "sudden death syndrome" whereby the concentrated inhaled vapors can sensitive cardiac tissues to catecholamine formation causing massive arrythmias and zero net cardiac output. The result, death. 208.11.188.26 16:24 Feb 1, 2005

Chemical Formula

Should we show up 1,1,1-Trichloroethane with CH₃CCl₃ rather than C₂H₃Cl₃?

Added the CH3CCl3. --Deryck C. 01:36, 30 October 2006 (UTC)

Name of article

In actual writing, we put the "t" in lowercase. Therefore name of this article should be "1,1,1-trichloroethane". I'm going to move this. --Deryck C. 01:33, 30 October 2006 (UTC)

Does 1,1,1 - Trichoroethane effect alcohol breath testing devices?

Evidentiary machines, used by policeforces, generally utilize infrared spectrophotometer technology. Essentially, the machines project an infra-red beam of energy through the captured breath in the sample chamber; the more energy is absorbed by compounds containing the methyl group in their molecular structures, the less reaches the detector on the other side -- and the higher the reading. The assumption is that the compound containing the methyl group is probably ethyl alcohol. However, studies indicate that over one hundred compounds containing the methyl group have been identified on the human breath and will be incorrectly detected as ethyl alcohol. Importantly, the effect is cumulative: the more methyl group compounds absorbing the infrared energy, the higher the false breath test result.

Greenhouse gas?

The article is in category:greenhouse gases, but the article makes no mention of it. Is it really a greenhouse gas as well as being an ozone depleting gas? Tim Ivorson 2008-03-18 13:06, 18 March 2008 (UTC)

Insecticide

Insecticide: The article mentions that a citation is needed that this chemical is harmful to insects. The http://www.alanwood.net/pesticides/methylchloroform.html page lists it as an insecticide. —Preceding unsigned comment added by 142.51.70.94 (talk) 15:47, 4 February 2011 (UTC)

Thanks for the suggestion. I have added the reference to the article. -- Ed (Edgar181) 16:14, 4 February 2011 (UTC)

Polar Solvent?

"1,1,1-Trichloroethane is generally considered as a polar solvent." Who does? It's a typical low-polarity solvent and does not dissolve medium or highly polar stuff. --FK1954 (talk) 20:08, 23 July 2012 (UTC)

Of course, 1,1,1-Trichloroethane is not really a polar solvent. But, like other halogenated (except fluorinated) hydrocarbons, it has a high polarizability. This makes it a good solvent for substances of low polarity, but not for strong polar compounds. btw: the odor is NOT chloroform-like (nearly no sweet flavor), it reminds me more of tetrachloromethane. --FK1954 (talk) 23:56, 6 November 2015 (UTC)

better solubility info than given in infobox

The infobox simply gives the solubility in water as "0.4%" at whatever temp., and the source gives only this information too. So I went off to find a more precise, equally reliable source -- http://www.inchem.org/documents/ehc/ehc/ehc136.htm -- which gives 3 alternative measurements and in turn cites their originators, AND gives the **units used - g/dm3** (i.e. w/v). If you're skilled at referencing, perhaps you'd like to change the info and citation over - it'd take me ages and I'd probably make mistakes. I'll mark the reference with a check template.

Fixed. Probably with an inappropriate cite template, but seems ok. Useful cross check for lots of the other data there too. Trev M  ~  22:10, 25 December 2017 (UTC)

Odor

Is very similar to tetrachloromethane, not like chloroform , without the intense sweetness of chloroform. Halocarbons with CHX-groups have a sweet odor (chloroform, 1,2-dichloroethane etc) cause the hydrogen of these groups forms a hydrogen bond to the "sweet"-receptors on the tongue. — Preceding unsigned comment added by 2001:9E8:4F6C:7B00:3499:4E52:D8FD:A5A1 (talk) 18:52, 15 February 2024 (UTC)

You will have to get a source on its odor being closer to tetrachloromethane. Right now Pubchem states that it's chloroform-like based on NIOSH and the Department of Transportation. Maybe change it to "sweetish" based on the more recent Ullmann's encyclopedia 7th edition? @FK1954 maybe you have some insight, since it's been brought up before. Reconrabbit 19:58, 15 February 2024 (UTC)

How trustworthy these sites are? NIOSH writes here tetrachloroethylene had a chloroform-like smell, when in reality, it smells quite different from chloroform. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 16:47, 16 February 2024 (UTC)

Too bad, this substance is banned and you are unlikely to find someone that knows what it exactly smells like. Considering that CCl4 smells like chloroform, I don't really see a problem with "chloroform-like" here (but this description has been overused for every chlorinated solvent).
