delocalised electron ring

The diagram shows alternating double and single bonds. Should this not be a delocalised electron ring? Does the image need to be changed? T23c 19:29, 17 January 2007 (UTC)[reply]

In Popular Culture section

This is kinda a minor thing but I removed the part saying "In the Radiohead song 'Fake Plastic Trees' (a crackpot, a styrene man)" because the lyrics in the official album liner notes say "a cracked polystyrene man". Perhaps that could be mentioned in the polystyrene article, then? --PsychoCola 23:13, 28 June 2007 (UTC)[reply]

The image of the 3D atomic structure of Styrene is wrong. It depicts ethylbenzene (C8H10), not styrene (C8H8). —Preceding unsigned comment added by 169.229.15.142 (talk) 22:26, 6 September 2007 (UTC)[reply]

nice catch.--Smokefoot 22:51, 6 September 2007 (UTC)[reply]

Yes, the 3D ball structure pic was wrong. I have made a new corrected one. I will upload it sometime. H Padleckas 05:34, 8 September 2007 (UTC)[reply]

Production via the "Shell process" (ethylbenzene hydroperoxide)

The ethylbenzene hydroperoxide formed by radical oxidation of ethylbenzene consist of nearly pure 1-Phenylethyl-1-hydroperoxide (Ph-CH(OOH)-CH₃), not 2-Phenylethylhydroperoxide; the alpha-aliphatic carbon is far more prone to this reaction (by mesomeric effect of the benzene ring). Objections against edit in this respection?--84.163.108.81 (talk) 17:54, 1 September 2008 (UTC)[reply]

Dipole moment

Where does the value for the dipole moment come from? I need a reference for that value. ---96.52.137.60 (talk) This article would be a little more useful to me if it also included the various uses of the chemical/solvent "styrene"142.166.177.102 (talk) 17:26, 4 August 2010 (UTC)[reply]

Classified as a Carcinogen by NIH

Page needs updating to reflect the National Toxicology Program's 12th Report on Carcinogens. http://ntp.niehs.nih.gov/go/roc12 Mattlistener (talk) 20:51, 10 June 2011 (UTC)[reply]

bioremediation?

I don't have access to the paper given as a reference, but the summary seems to be about growing the fungi on styrene and nothing about cleaning it out of the air. Seeing as the fungi causes a serious infection (follow the link) I doubt it is used for bioremediation. Maybe this section is a guess on the authors part??? — Preceding unsigned comment added by 121.91.2.247 (talk) 12:05, 13 August 2014 (UTC)[reply]

Reaction temperature (and pressure!)?

In the section on production by dehydrogenation one important condition is left out: the typical reaction temperature. Although Wikipedia is good the quality of synthesis and production sections is quite variable with temperatures or other conditions frequently left out. Apart from the missing temperature this article was rather good although more details could improve it. The statement that the reaction is run under vacuum is debatable, obviously the reactants must be there! It would be more accurate to describe it as a low-pressure process and state the pressure. — Preceding unsigned comment added by 150.227.15.253 (talk) 12:07, 1 July 2016 (UTC)[reply]

Thanks. Very helpful. Wikipedia makes no pretense to give procedural information, or details as a matter of policy. It views itself as an encyclopedia, not a text or manual or technical journal. See WP:NOTMANUAL and similar WP:NOT's. Lots of reactions are run "under vacuum." Perfect vacuum? Certainly not. There is some virtue in avoiding the cumbersome language that states the obvious - perfect vacuums are never achieved. --Smokefoot (talk) 12:29, 1 July 2016 (UTC)[reply]

Preferred IUPAC name

I found both styrene and ethenylbenzene mentioned as preferred IUPAC name. If I'm not mistaken, I found even both in a sigle document: https://old.iupac.org/reports/provisional/abstract04/BB-prs310305/Chapter1.pdf (styrene at p.4, ethenylbenzene at p. 14).

Could someone with a proper chemical education please clarify? — Preceding unsigned comment added by Le Monsieur Paul (talk • contribs) 17:31, 26 March 2019 (UTC)[reply]

Greetings, Pharmacist here. Styrene is more like a common name. A proper name according to IUPAC should be Ethenylbenzene. 45.188.78.251 (talk) 22:14, 5 February 2024 (UTC)[reply]

Issues with source "OPPT Chemical Fact Sheets (Styrene) Fact Sheet: Support Document (CAS No. 100-42-5)"

The real link is broken and currently redirects to a general information page on TSCA chemicals on the EPA webpage. The archived version of the PDF still works, but reading the actual document, it never calls styrene a "known carcinogen" as the article text suggests. In fact, the section on carcinogenicity begins, "The evidence for carcinogenicity of styrene is limited."

On the basis of these issues, perhaps the citation should be removed or the text should be corrected to state that this particular (admittedly older) archived document does not identify stryene as a carcinogen.
