Nomenclature

I hope the old name "ethylene dichloride" is phased out soon, as it implies a double bond where there isn't one (compare to ethylene). 1,2-dichloroethane is definitely less misleading. Eddietoran (talk) 02:57, 18 August 2011 (UTC)[reply]

Safety

While the chemical is banned from use by U.S. manufacturers

The chemical may be banned from use as an additive, but it is certainly not banned from use by manufacturers in the US as an intermediate or as a raw material. Hundreds of thousands of tonnes of ethylene dichloride are consumed in the US every year for the manufacture of PVC. — Preceding unsigned comment added by 213.225.149.5 (talk) 14:56, 17 December 2013 (UTC)[reply]

DCA vs DCE abbreviation

This compound is almost exclusively known as DCE in the chemical literature. I know DCA would make it clearer than DCE (to distinguish from dichloroethene), but the fact of the matter is general usage states it's DCE.

For example, the following is a good example (behind paywall, though). http://onlinelibrary.wiley.com/doi/10.1002/anie.200462207/full

Comparing searches on Google Scholar as well gives me the following. I only included since 2010 to get a feel of the current usage of things. Still, results are similar regardless of timeline: Searching 'dichloroethane DCA' gives 814 results (http://scholar.google.com/scholar?q=dichloroethane+DCA&btnG=&hl=en&as_sdt=0%2C5&as_ylo=2010) Searching 'dichloroethane DCE' gives 8320 results (http://scholar.google.com/scholar?q=dichloroethane+DCE&btnG=&hl=en&as_sdt=0%2C5&as_ylo=2010)

We shouldn't be calling it DCA on this page, and I've changed it back to DCE. — Preceding unsigned comment added by Stever Augustus (talk • contribs) 22:43, 5 November 2014 (UTC)[reply]

Also, the PubChem^[1] and ChemSpider^[2] pages for 1,2-dichloroethane list DCE as a synonym multiples times (with no mention of DCA), as does the Journal of Organic Chemistry.^[3]. It makes sense to use DCA to avoid confusion with DCE, but the evidence of useage doesn't seem to support that. --tronvillain (talk) 17:53, 21 June 2016 (UTC)[reply]

Ok, I removed the lightly used or confusing acronym.--Smokefoot (talk) 17:24, 21 June 2016 (UTC)[reply]

Perhaps something in the introduction or the history section? I see dichloroethene mentions it under "see also."--tronvillain (talk) 18:20, 21 June 2016 (UTC)[reply]

When I worked in the environmental cleanup industry, this was a constant issue because dichloroethane and dichloroethene are common groundwater contaminants. To distinguish the two, in the environmental field DCE is used exclusively for dichloroethene and DCA is used for dichloroethane. There is plenty of evidence in the scientific literature that DCA is used as an abbreviation for dichloroethane. Here are a few examples: https://www.ncbi.nlm.nih.gov/pubmed/24468425 https://www.ncbi.nlm.nih.gov/pubmed/10388710 http://aem.asm.org/content/65/7/3108.full -- Ed (Edgar181) 14:55, 5 January 2018 (UTC)[reply]

There's also plenty of evidence that DCE is used in the chemical field, whether or not it's used in "the environmental field" specifically. You'll notice I didn't remove the addition of 1,2-DCA from "other names." --tronvillain (talk) 15:54, 5 January 2018 (UTC)[reply]

I agree. I shouldn't have removed DCE when I reverted 58.32.236.249. You were right to reintroduce it. -- Ed (Edgar181) 16:00, 5 January 2018 (UTC)[reply]

It might actually be worth mentioning the naming conflict in the article itself.--tronvillain (talk) 16:19, 5 January 2018 (UTC)[reply]
