i just wanted to know the effect of the OH group on the reactivity of the benzene ring in phenols? —Preceding unsigned comment added by Tanu786 (talkcontribs) 16:30, 23 September 2010 (UTC)



I have one doubt, this phenol is not completely miscible in water, then how the scientists are making a solution of phenol for experimental analyis,say, particular ppm for degradation analyis. please clarify my doubts

vijaya kumar V,

India, Thanking you,

In response to Vijaya, I have recently made a solution of 80 %(w/w) phenol (crystalline) in water with no problems.
About the page, should we have the hydroxycinnamic acids added to the list on this page eg ferulic acid, coumaric acid and vanillic acid/vanillin. The former don't seem to have pages, but vanillin does, and I would count that as a phenolic. Terri G 11:32, 10 April 2006 (UTC)

Introduction copied[edit]

I'm not sure why the last person to comment (in the history) was bothered about the introduction being copied, seeing as it's an open licence. Terri G 10:11, 6 September 2006 (UTC)

good day!

Im an inefction control nurse in a hospital, how do I know that a particular disinfectant contains phenol? thank you!

O-alkylation of phenos[edit]

When phenol reacts with ethyl iodide in the presence of aqueous sodium hydroxide and heat, it forms ethy phenyl ether or phenetole. What happens to the iodine? Is it converted to any by-product? If yes, then what is it?

Thanks Divya (SYBSc student)

P.S. We were told about two years back that if HI (in any form) is formed in any organic reaction, it is unstable. So that is why this question cropped up.

Iron(III) choride test[edit]

There should be some information on the test for phenols. A neutral iron(III) choride solution will turn purple when it is added to phenol and its derivatives. Lmatt (talk) 21:27, 10 June 2009 (UTC)

Need for further concerted editing[edit]

This document is extraordinarily weak, relative to the richness of the subject, and needs expert attention. Prof D

Where we stand[edit]

Today I merged the content of the natural phenols article into this one. That article was badly sourced and essay-like - basically it is all WP:OR. I am taking a break from this now and want to get some feedback while I am gone. The "occurrences" section is a cherry-picked, random laundry list, rather than something useful and encyclopedic. And it is way too long, giving that section undue weight. This is the result of prior editors using primary sources instead of following secondary and tertiary sources which is exactly what WP:OR warns against. So here is my question - namely, how to reorganize that section (using secondary sources of course). We could organize it by the phenolic compounds themselves, discussing just the most common ones, where they are found, and what their role is. (Or the same but classes of phenolic compounds) Or we could focus on roles, and have just a few examples of the phenolic compounds and what organism use them for each role. Or something else. What do you think? Jytdog (talk) 00:23, 3 March 2013 (UTC)

Is listing the occurrences even necessary? It does add a lot of bulk/fluff to the article. (I can see listing the what phenol was a component of when it was first discovered, but that's already covered in the phenol article.) Stating that so-and-so organism uses/produces/excretes a very specific phenol that already has its own Wiki page just seems like a waste of space in my opinion. The roles sections were at least informative and interesting (and read much less like a list!), but I'm not sure if that has any bearing on whether or not something should be on Wikipedia.

Thanks for weighing in! We are on the same page there and I will probably take that stuff out if you don't beat me to it. btw, while I am sure you had good intentions in editing my post above, that was bad form... you are always free to edit the article but you should not mess with what somebody else writes on a Talk page. see WP:TPO Jytdog (talk) 03:20, 1 April 2013 (UTC)
My apologies! I've skimmed WP:TPO before but must've completely missed that bit. I'll let you remove the fluff, since I'd be tempted to do some major hack and slashing. Would it be appropriate to create a separate list page for naturally-occurring phenols? Or should they just be removed and leave it at that? Zaryn (talk) 19:56, 3 April 2013 (UTC)
Its OK, now you know! I am not a fan of list pages, but you are free to create one, of course. Be careful to avoid creating content is not encyclopedic, though -- see WP:NOT Jytdog (talk) 12:01, 9 April 2013 (UTC)
I found the style manual for stand-alone lists: WP:SAL. I'll read it over well (no skimming!) and then try to determine if creating the list would be appropriate. Zaryn (talk) 15:06, 9 April 2013 (UTC)
This morning I broke the table of phenol compounds into two lists, one for naturally occurring and the other for synthetic (there was already a drug table). I was thinking about taking some of the content out of the "occurrences" section and just adding it to the table, as a starting point. But I want some sense of order or reasoning... which was the reason for my initial inquiry above. It is useful to have some examples but there are too many now, we agree. btw there is an editor called "NotWith" who is responsible for a lot of the content on these pages... his/her edits are... difficult. Lots of OR, and the kind of shotgun random listing of stuff like we are discussing now. Gotta give kuodos to NotWith for generating content but it is problematic. You may have noticed that he/she came around last night/this morning and restored content that I had deleted a while back.. which I re-deleted. Hoping that NotWith shows up here so we can talk. 15:16, 9 April 2013 (UTC)
I just saw all of the edits -- yikes! Not sure if you noticed but NotWith seems to be the only active member of Wikipedia:WikiProject Natural phenols and polyphenols, which at one point was considered for deletion and is now in userspace. Part of the "to do" list was to identify sources of phenols, which might explain the huge revert by NotWith. I'll leave a note on their talk page and invite them to come chat with us.Zaryn (talk) 16:05, 9 April 2013 (UTC)
