I don't want to get in an edit war on this, so I've left the numbers as typical figures.
It seems to me to make more sense to do this than to add the recommended limits for the UK, India, Japan... etc.
The alternative would be to link to a page of national limits for exposure to this, but I don't think it's worth the effort, especially as the same argument would apply to any dangerous chemical.
Perhaps another approach would be to leave the "typical" figures as per my edit, and put the sources as links at the end? jimfbleak 15:56 13 Jun 2003 (UTC)
Reasons for name change: Tetrachloromethane is the IUPAC name, but aside from IUPAC zealots, no one seems to call it that. Google statistics:
carbon tetrachloride: 63,000 tetrachloromethane: 4,310
Additionally, carbon tetrachloride is the primary entry in the Merck index and just about every chemical catalog.
Just a notice, there are 2 physical properties sections on the page to the left, everything is the same except the melting point. (BTW This is my first comment so please pardon me if this wasnt an error)
Why is this article under the "Hepatitis" Category? I see no relationship. If no one objects, I am going to remove it. Bonus Onus 00:41, Mar 9, 2005 (UTC)

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)
I am removing the entire text
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)
An anon changed the name in the article, and not very elegantly. The edits were before those of User:Carbonferum, who also seems to have copied a picture from the japanese wikipedia in another article. Dunno i Carbonferum and the anon are the same people. I'll fix this later if i remember, and no-one else does :-D. Tristanb 06:00, 25 May 2005 (UTC)
If carbon tetrachloride (CCl4) dissolved in benzene (C6H6) [and it can], would they both still be toxic? Random the Scrambled 12:17, 1 May 2006 (UTC)
At any temperature, Carbon Tet is not flammable at all. So is Chloroform and Dichloromethane.
Chloroform and DCM will actually burn when mixed with flammable material, and yes, they produce phosgene and dioxins 134.147.247.12 (talk) 11:36, 5 January 2009 (UTC)
I think it is highly unlikely that Carbon tetrachloride to form phosgene. It would have to be reacted with a phosphorus bearing compound, it would not spontaneously form phosgene as the article and your comment claim. Iepeulas 20:09, 12 September 2007 (UTC)
My bad, I thought phosgene contained phosphorus, it does not. I removed the unverified template. Iepeulas 20:12, 12 September 2007 (UTC)

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.

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)
---I would suggest that it should be considered organic from the perspective that in the family of chlorinated methanes, the rest would all be considered organic. — Preceding unsigned comment added by Gpronger (talk • contribs) 17:36, 21 August 2014 (UTC)
Hey, just thought you might want to throw this in the article but I'm having trouble with verification and hoped someone else might have better luck. According to Organic Chemistry 4th Edition by G. Marc Loudon, page 318, production of CCl4 was banned in 1996. I can't find much on it, and Loudon doesn't provide a source, but I'm loathe to believe that verification is impossible. EagleFalconn (talk) 15:49, 18 July 2008 (UTC)
The first question that popped into my mind when I read this section heading was "where?". It makes no sense to talk of a chemical being banned without specifying where. Some chemicals may be banned in the U.S. but not in China, or they may be banned only for certain uses. CCl4 certainly seems to be "deprecated", but is still available for some uses. --Itub (talk) 16:14, 21 July 2008 (UTC)
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)
I was a metal machinist in the 1980s. Until it was banned, carbon tetrachloride was applied to the cutting tool while cutting grooves that required very smooth finishes, with a small groove radius. The machine spindle had to be operated at very high RPM to achieve the radial velocity for cutting. The grooves were "plunged", it was an art to do this on a manual machine because the cutting tool could not "rub" at the end of the plunge, else "chatter" would occur marring the groove finish. In effect you had to be fast enough to pull back at the end of the plunge before the spindle made another revolution. Carbon tetrachloride was applied to the cutting surface during the cutting plunge. I do not know the physics behind it, but it produced very good finishes on the metal, and was sorely missed by the machine operators after the ban. 173.25.223.151 (talk) 01:31, 7 August 2011 (UTC)

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)
Apparently Carbon Tetrachloride was very important in the first half of the 20th C. in the treatment of hookworm. https://www.pbs.org/wgbh/nova/article/how-a-worm-gave-the-south-a-bad-name/ 47.180.216.128 (talk) 04:50, 22 September 2021 (UTC)

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)
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)
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)
