:Carbon tetrachloride persisted as an aerosol propellant and...
Huh? The boiling point at 1 atm is 77ºC. Aerosol propellants need to have a bp lower than STP. Clearly it can't be a propellant, but what was meant here? -- Securiger 16:08, 16 May 2005 (UTC)
replies: text: I have removed the claim that it was used as an aerosol propellant. It is physically impossible for carbon tetrachloride to serve as an aerosol propellant at STP, and I have found no references hinting at what might have been meant here. I suspect confusion arose from the fact carbon tetrachloride was used in the production of CFCs (some of which were used as aerosol propellants), a fact which is already mentioned in the next paragraph. -- Securiger 05:38, 22 May 2005 (UTC)

Noted MIT researcher Dr. Makhlook Singh has noted that carbon tetrachloride has been observed to create psychedelic behavior in rats exposed to it in low concentrations for a long period of time. Dr. Singh pointed out that it may have useful medical properties if it could be refined and blended with other anti-depressant drugs, such as asycomycotacol or indiamycotacolis. He noted the latter, when blended with carbon tetrachloride, reversed noticeable brain synapse damage through, as he calls it, the Bombay effect. As he says, much research is needed to determine if any long term risks are present in the medical use, but it may radically change the process of treating such disabilities from simple depression to previously-irreversible neurological synapse damage. There is much promise in this research for those affected by neurological disorders. 
Upon first reading it seemed to be absurd - but it captured my attention nonetheless because it was so full of improbability Psychedlic carbon tetrachloride! That brings a whole new meaning to disolving mental boundaries! Unfortunately, this proved to be mere vandaliasm, and I have done the following with Google to confirm: Verified that asycomycotacol appears to be a made up word. Verified that indiamycotacolis also appears to be a made up word. Verified that if there even is a Makhlook Singh at MIT or anywhere else, he sure is NOT noted, as claimed. The Bombay Effect also sounds like something out of a hollywood script rather than a researcher.
While the prospect of some college kid getting totally busted turning in a report mentioning any of the text in the vandalism, the prospect of some overinteligent and underwise junior high kid trying it out Zaphraud 22:54, 15 January 2007 (UTC)

message: I have found 2 other sources that list the solubility in water as 785 - 800 mg/L and not the 8 mg/L shown in the article. See www.inchem.org/documents/ehc/ehc/ehc208.htm and www.atsdr.cdc.gov/toxprofiles/tp30-p.pdf. Also I work with the Department of Toxic Substances Contol/Cal EPA and one of the carbon tetrachloride contaminated groundwater plumes would have concentrations far in excess of the solubility if 8 mg/L were correct.

message: I find the article belongs to the category of Inorganic carbon compounds. As this compound is also a haloalkane, I doubt whether it is organic or inorganic compound. -Quest for Truth (talk) 19:20, 17 February 2008 (UTC)
replies: text: The decision what compound is organic or inorganic is less hard than it sounds and it is done more of historic reasons and looks at the context. CHCl3 organic  and CCl4 inorganic is OK for the hard criteria of C-H bonds but does not make sense., The compound O=C(NH2)2, O=C(OH)2 are both more inorganic, but the first is counted organic (urea). In the context CCl4 should stay organic!--Stone (talk) 06:46, 18 February 2008 (UTC)
replies: text: Thank you for Stone's quick reply! So you also think that CCl4 should get out from the list of inorganic compound and we should amend the definition of organic compound? --Quest for Truth (talk) 12:44, 19 February 2008 (UTC)
replies: text: I don't think the category hurts. Some people consider it organic, some inorganic, because the exact division is a bit fuzzy and arbitrary. It can be in both categories. --Itub (talk) 13:27, 21 February 2008 (UTC)
thread_title:  Organic or Inorganic? 

message: Section 'History and Synthesis', eighth line. The correct prefix for chlorine is chlor(o)-. So it should spell 'chlorolysis'. Besides, to me it's simply combustion (oxidation by chlorine to highest oxidation state), not 'chlorolysis'. Burning ethane breaks it into carbon dioxide(oxidation to highest oxide) and water, is it 'oxolysis' then? Zhieaanm (talk) 01:09, 15 January 2009 (UTC)
replies: text: Google reveals about 6000 uses of the term. One of which describes "A process termed chlorinolysis (exhaustive chlorination) was applied to..." Merriam-Webster also has a definition but you have to pay to reach it. Rmhermen (talk) 18:04, 13 May 2009 (UTC)

Many thousands of uses for many common chemicals have been devised over the centuries, and while such apps are often interesting and charming, their notability is debatable and the inclusion of such anecdotes potentially can interfere with readability ("my pappy used xyz to kill ants" type stuff). --Smokefoot (talk) 13:32, 7 August 2011 (UTC)

message: The pop up states that a molecule is "electrically neutral". This is not true. Water, for example is a molecule but it is extremely polar. Likewise, acids and bases, HCl and NaCl, for example, although being molecules, each have electric charges in their natural state. Although not alway written that way, many molecules, such as H2O, exist as ions when in their normal states (in the case of water, those ions are H+ and O-.). Although most molecules are stable, they are not "electrically neutral" as the pop up claims. My humble suggestion is to find another source for an explanatory pop up, or just drop it altogether. As stated, this is IMHO. (Thank you for taking the time to read this recommendation.) L. Tringo Rudolph (talk) 21:13, 2 February 2021 (UTC)

message: (Read my post on https://en.wikipedia.org/wiki/Talk:Tetrachloroethylene#Discovery)
I have read Faraday's alleged discovery of tetrachloroethylene and it is clear that the compound he synthesized was carbon tet and not tetrachloroethylene. The compound made by Regnault in 1839 was actually tetrachloroethylene.
I compared given properties of 2 "chlorides of carbon" by Regnault and Faraday with carbon tet and tetrachloroethylene. Faraday says that his chloride of carbon did not react with chlorine and boiled at around 160~170 degrees F 176.88.97.55 (talk) 15:43, 17 January 2023 (UTC)
thread_title:  Discovery 

message: I don't remember where I read it, I remember seeing in multiple articles that alcohol consumption worsens carbon tetrachloride poisoning. It was definitely something related to  metabolism in the liver. In one case, a woman cleaned a cloth with carbon tetrachloride but her husband who drunk alcohol in the past days died from exposure while the wife was fine (this was mentioned in a booklet by the American government). It seems like this was a common hazard. 
Does anyone have a medical source for this phenomenon? Saint concrete (talk) 05:05, 13 August 2023 (UTC)

message: Seeming slightly over the top, this article is a magnet for various warnings and regulations.  If carbon tet were even close to an acute poison, tens of thousands of stamp collectors would have keeled over when they used this stuff liberally for watermarking back when that hobby was popular.--Smokefoot (talk) 14:32, 11 November 2023 (UTC)
replies: text: I read Maurice Hall's report and he mentions about 30,000 women had their hair washed with carbon tet in early 20thc and the illnesses (mostly fainting) were rare with only one death reported. I came across something similar few months ago in another research on the chemical; only a few had illness in tens of thousands of people who were given a single or one more dose of carbon tetrachloride. Those who were affected by carbon tetrachloride after a short exposure were usually those who consumed alcohol, frequently or recently. Saint concrete (talk) 22:37, 14 November 2023 (UTC)
