Talk:Resorcinol

Supramolecular Chemistry

I reformated the "Applications" section giving it subheadings for medical and chemical uses of resorcinol. I also added a short paragraph on the use of resorcinol as a template molecule in supramolecular chemistry. Mrestko 01:15, 2 May 2006 (UTC)

From Britannica

I was previously worried (deleted message) that this article was plagerized, but reading the notes on the edit history, the material is taken from an old Encylopedia Britannica, which is allowed I guess. Still the writing is dense, but obviously the content is terrific.--Smokefoot 23:28, 20 June 2007 (UTC)

Who invented it?

Who invented resorcinol? I think he was a Russian chemist. I believe it was invented in Japan many years ago.

Major use as a glue not mentioned?

I came here wanting to learn more about resorcinol glue - a major wood glue, especially in marine applications. If someone knows more, wouldl be great to add a section on this use. —Preceding unsigned comment added by Tim bates (talk • contribs) 10:38, 22 May 2009 (UTC)

This page is missing a fire diamond for this chemical

Also resorcinol along with acetic acid forms resacetophenone.

history

VexorAbVikipædia the content you introduced here and edit warred back in here is OR|original research - you are saying the publication you cite was the the one showing the invention. you need a secondary source that says that. Jytdog (talk) 01:35, 19 April 2015 (UTC)

First of all, I am NOT engaged in any "edit war". You asked for a reference stating that Hlasiwetz and Barth discovered resorcinol in 1864. I provided FIVE references stating that Hlasiwetz and Barth discovered resorcinol. I even provided a scan of the 1864 Anzeiger der Kaiserlichen Akademie der Wissenschaften in which Hlasiwetz and Barth presented their paper to the Imperial Academy of Science, where the secretary stated that they had discovered a new compound, "resorcin". I provided links to ALL of these sources. I did what you requested and yet you're still upset. I am completely confused. VexorAbVikipædia (talk) 02:05, 19 April 2015 (UTC)

oh crap! i totally missed that you had included the boatload of references in that second diff. totally missed that. i am very very sorry. striking above, and i'll remove the notice from your page. Jytdog (talk)

I think that what you really want is a secondary source that states that Hlasiwetz and Barth discovered resorcinol in 1864 and that the reference that I provided is the correct one. Okay, here are two more secondary sources that state just that:

• Raj B. Durairaj, Resorcinol: Chemistry, Technology and Applications (Berlin, Germany: Springer, 2005), p. 10: "Resorcinol was first prepared in the laboratory in 1864 [1-3]." https://books.google.com/books?id=iJ94n7GHuUAC&pg=PA10#v=onepage&q&f=false

p. 33: "References 1. H. Hlasiwetz and L. Barth, Ann. Chem. Pharm., vol. 130, p. 354 (1864)." https://books.google.com/books?id=iJ94n7GHuUAC&pg=PA33#v=onepage&q&f=false

• Pompejus Alexander Bolley, et al. Die theerfarbstoffe (Dyes from tar), volume 2 (Braunschweig, Germany: Friedrich Vieweg und Sohn, 1880-1883), p. 585: "Das Resorcin wurde 1864 durch Barth und Hlasiwetz (2) entdeckt … " (Resorcin was discovered by Barth and Hlasiwetz (2) in 1864 .. ) Footnote (2) at the bottom of the same page: Liebig's Annalen 130, 354. https://books.google.com/books?id=r_8MAAAAYAAJ&pg=PA858#v=onepage&q&f=false

For your purposes, these secondary sources may be better than the ones that I provided earlier, because they not only state that Hlasiwetz and Barth discovered resorcinol in 1864, but they also provide the citation that I posted. VexorAbVikipædia (talk) 02:52, 19 April 2015 (UTC)

don't know if you noticed, but i went ahead and included the content you wanted, with secondary sources. feel free to add the ones you found if you like. this matter is resolved for me. i apologize again - your 2nd edit was great. Jytdog (talk) 03:13, 19 April 2015 (UTC)

Missing reactivity type

Resorcinol tautomerizes to the 1,3 diketo 4 cyclohexene which behaves like a a,b-unsaturated ketone to add cyanide or sulfonate (from Sulfite) anions to position 5. Copper Hydride, from Copper powder and NaOH, the Hydride anion adds to position 5 giving dihydroresorcinol aka 1,3Cyclohexanedione. TaylorLeem (talk) 01:20, 13 June 2020 (UTC)

To add to article

To add to this article: mention of phenylethyl resorcinol and SymWhite® 377. 173.88.246.138 (talk) 22:49, 16 December 2021 (UTC)

Confusing electrophilic with nucleophilic

Not mentioned is Resorcinol structure is also represented by Cyclohex-4-ene 1,3 dione and Cyanide, Sulfite, Copper Hydride, et al add to the activated double bond giving 5 substituted dihydro derivatives. TaylorLeem (talk) 01:45, 3 June 2022 (UTC)

The §Reactions section notes "In addition to electrophilic aromatic addition, resorcinol (and other polyols) undergo nucleophilic substitution via the enone tautomer." Seems like that is a first hint of the ene-dione form, and this section which could be expanded with a diagram and some cited examples. DMacks (talk) 02:12, 3 June 2022 (UTC)

@TaylorLeem: you seem to have first noted this content-lack two years ago (a few sections earlier on the talkpage). You seem to have some good scientific ideas, why not have a go at writing it yourself? Be sure to add a ref or two. "Be bold" is a standard guideline on the 'pedia.

resorcinol not added to REACH

although it was a candidate for the European Union's REACH as an endocrine disruptor in 2022, wasn't it removed? 75.172.54.250 (talk) 15:19, 5 February 2024 (UTC)
