Talk:Tetrachloroethylene

add regulatory efforts?
There is no discussion of regulatory efforts, such as EPA https://www.epa.gov/stationary-sources-air-pollution/dry-cleaning-facilities-national-perchloroethylene-air-emission Thanks.38.105.242.2 (

Interesting thread on the problems with drycleaners esp. in stripmalls, worth linking somehow?: https://twitter.com/realestatetrent/status/1437802803313922051 5.145.10.140 (talk) 17:14, 17 June 2022 (UTC)

Discovery
I have read both Victor Regnault's 1839 report and Faraday's 1820 discovery in his 1850s work and compared 2 compounds that both have discovered via thermal decomposition of hexachloroethane. Whatever Faraday synthesized in 1820,was carbon tetrachloride and not tetrachloroethylene as this article suggests. Faraday mentions that this compound of carbon and chloride did not react with chlorine and boiled at 160~170 degrees Fahrenheit (which are the properties of carbon tet). The other carbon chloride that V. Regnault synthesized in 1839 by the same process did not boil until 120 degrees Celsius. Faraday mentions that his chloride of carbon has a density of 1.55, carbon tetrachloride's density is 1.58 and tetrachloroethylene's is 1.62. Which one sounds closer? Victor Regnault's 1839 chloride of carbon reportedly has a vapour density of 5.83. Remember, he is commonly credited for carbon tetrachloride which has a vapour density of 5.3 and not tetrachloroethylene which has a vapour density of 5.7. 176.88.97.55 (talk) 15:39, 17 January 2023 (UTC)

Highly cited review
By far the most cited review on tetrachloroethylene according to Chemical Abstracts:

"A review. Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chems. that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chems. as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene. Since 2006, epidemiol. studies have documented six addnl. developmental neurotoxicants-manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated di-Ph ethers."

 * It doesn't feel "convincing" enough; you can't really know what effects would tetrachloroethylene have among many other chemicals on people (that's also why researches on dry cleaners are not convincing enough, too many other chemicals). If there are very strong neurotoxins like methylmercury compounds and toluene, you can't seperate their certain effects from tetrachloroethylene's possible effects. I feel like including this paper would make readers go "dry cleaning causes autism/ADHD/dyslexia". Researches involving multiple chemicals are flawed and shouldn't be cited for a suspected single chemical, in my opinion. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 22:45, 16 May 2024 (UTC)

"A review. This paper reviews recent achievements and the current status of non-thermal plasma (NTP) technol. for the abatement of volatile organic compounds (VOCs). Many reactor configurations were developed to generate a NTP at atm. pressure. Therefore in this review article, the principles of generating NTPs are outlined. Further on, this paper is divided in two equally important parts: plasma-alone and plasma-catalytic systems. Combination of NTP with heterogeneous catalysis has attracted increased attention to overcome the weaknesses of plasma-alone systems. An overview is given of the present understanding of the mechanisms involved in plasma-catalytic processes. In both parts (plasma-alone systems and plasma-catalysis), literature on the abatement of VOCs is reviewed in close detail. Special attention is given to the influence of critical process parameters on the removal process."

cited 138x " A review is given. Chlorinated solvents such as trichloroethene (TCE) and tetrachloroethene (PCE) are widespread groundwater contaminants often released as dense nonaqueous phase liquids (DNAPLs). These contaminants are difficult to remediate, particularly their source zones. This paper summarizes the progress made in improving DNAPL source zone remediation over the past decade, and is structured to highlight the important practical lessons learned for improving DNAPL source zone remediation. Experience has shown that complete restoration is rare, and alternative metrics such as mass discharge are often useful for assessing the performance of partial restoration efforts. Experience also has shown that different technologies are needed for different times and locations, and that deliberately combining technologies may improve overall remedy performance. Several injection-based technologies are capable of removing a large fraction of the total contaminant mass, and reducing groundwater concentrations and mass discharge by 1-2 orders of magnitude. Thermal treatment can remove even more mass, but even these technologies generally leave some contamination in place. Research on better delivery techniques and characterization technologies will likely improve treatment, but managers should anticipate that source treatment will leave some contamination in place that will require future management.
