Talk:1,2-Dichloroethylene

Is this compound ever polymerized? --83.100.0.21 (talk) 14:50, 19 September 2008 (UTC)

Untitled
trans 1,2-dichloroethene is commonly used as a component of modern vapor degreasing solvents made by DuPont (http://www2.dupont.com/Vertrel/en_US/assets/downloads/pdf/k04183.pdf) and Microcare ( http://www.microcareprecisioncleaners.com/wp-content/uploads/sites/6/2014/10/PDS_-_HDS_10-10.pdf). As such, it's probably worth removing the "scarcely any industrial applications" remark from Ullmann's encyclopedia.Rdnckj258 (talk) 21:55, 22 April 2015 (UTC)

Odor?
Although at least one reference describes the odor of 1,2 trans-dichloroethylene as sharp, acrid, or pungent, this is not consistent with its actual odor. It is sweet and ethereal. Note that it is also described as "chloroform-like" - and chloroform is not sharp, pungent, or acrid; it is sweet and ethereal. Anyone who has worked with a 1,2 trans-dichloroethylene degreaser knows the odor is pleasant and not as described in the article. Perhaps someone will go to the trouble of finding a reference for this and making the edit. — Preceding unsigned comment added by 98.164.140.146 (talk) 05:43, 20 June 2022 (UTC)

Article name
I think the article name should be changed to 1,2-dichloroethylene as ethylene derivatives are commonly known as "something-ethylene" and not "something-ethene", like trichloroethylene and perchloroethylene. Saint concrete (talk) 11:23, 19 August 2023 (UTC)

Could this be 1,2-dichloroethylene?
I came across with a chemical name "chloromethylase" given the formula CHCl (C2HCl in old notation) in Gmelin's Handbook of Chemistry (an "old but gold" resource for histories of many organic chemicals). It was made by the decomposition of methyl trichloroacetate by potassium hydroxide. This is a liquid and was discovered by Laurent in 1836.

– Consistency with trichloroethylene and tetrachloroethylene, also not to confuse with the similar-sounding 1,2-Dichloroethane ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 19:19, 15 April 2024 (UTC) — Relisting.  ASUKITE  16:17, 26 April 2024 (UTC)
 * 1,2-Dichloroethene → 1,2-Dichloroethylene
 * 1,1-Dichloroethene → 1,1-Dichloroethylene
 * 1,1-Difluoroethene → 1,1-Difluoroethylene


 * Comment Agree in principle, but per WP:CONSISTENT we should not be considering this in isolation, as there is also 1,1-Dichloroethene, 1,1-Difluoroethene, but then we have 1,2-Difluoroethylene and 1,2-Dibromoethylene. There have been bold moves back and forth for the fluoro ones, so it would be best to have a multi move RM to settle the issue conclusively by consensus, rather than taking them one at a time.

 * @ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ, any opposition to expanding this move to include the additional suggestions and relisting it? ASUKITE  15:34, 26 April 2024 (UTC)
 * No opposition on my side, I support the decision to move other "-ethene"s to "-ethylene"s. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 15:58, 26 April 2024 (UTC)


 * Support I stated on 1,1-Dichloroethene that vinylidene chloride was the least ambiguous name, but this proposal is probably better because it's more consistent across multiple pages. Recon  rabbit  16:42, 26 April 2024 (UTC)

*:On second thought, we should establish which is preferred between 1,2-Difluoroethylene and 1,2-Dibromoethylene, if that isn't clear a new RM might actually be easier. At the moment it looks like this can be closed as "moved" any time unless somebody else comes along and disagrees, but I'll leave both options open for now.

 * Support. Based on my experience, I think ethylene is much more common than ethene in both technical and non-technical contexts.  The consistency across multiple articles would be an improvement too.  Marbletan (talk) 18:19, 26 April 2024 (UTC)
