As a Drug
- Yeah I was searching for information on ether as a drug, but all I found was its chemical properties. Someone should add it. CheesePlease NL 11:38, 26 September 2007 (UTC)
- Yeah I came here to find out more about it's use as an anaesthetic, but it's just a page of scientific forumula and information only useful to scientists. -NeF (talk) 01:13, 25 July 2008 (UTC)
Well, I know of a site called erowid.org that has information on pretty much every type of drug that you could imagine, and ones you couldn't. It has some stories about trips on Ether and the like, that I've been currently reading up on. Here's the link to the Ether section of the site:
Along with the first time recreational use stories that people have posted:
The first link has a link to the general trip stories, as well as links to info about the history of the drug and the like. The first story I read about Ether usage was this (and another one listed below it to show others ways it effects people):
Some pretty interesting stuff, but I don't see why people would use stuff like Ether and Dizocilpine for recreational uses. They seem way too dangerous and unstable for that sort of usage. KiwiMaddog (talk) 03:08, 14 March 2009 (UTC)

- I'm suprised no one has mentioned this, but ether refers to a whole class of organic compounds. The drug known in colloquial use as "ether" refers specifically as diethyl ether i.e. the one with medical and recreation drug use. This is mentioned at the start of the article, though it might not have been when this discussion started. — Preceding unsigned comment added by J1812 (talk • contribs) 04:59, 10 January 2013 (UTC)
How does it smell?
In the sidebar, furan is shown as an aromatic compound that is not an ether. Furan is the prototypical aromatic ether and is the unsaturated form of THF (hence tetrahydrofuran)
The funny thing about the Michaelson-Morely experiment is that Einstein was already formulating relativity before he knew anything about it.
Also, wasn't the root of the english word "ether" the Latin word "aether", which means "air" as in "the sky".
You sure aether doesn't refer specifically to the upper air, which corresponds to the fifth element that fills all of space? Its Greek equivalent does, at least.
- Despite their comparably attenuated reactivity, ethers can act as Lewis acids (see Acid-base reaction theories). For instance, diethyl ether forms a complex with boron compounds, such as boron trifluoride etherate, F3B:O(CH2CH3)2
Wouldn't the ether be the Lewis base here? Josh Cherry 00:59, 23 Oct 2003 (UTC)
The article states that the "x y ether" nomenclature is official IUPAC nomenclature; I don't want to edit the article as I may be wrong, but I'm sure that I was taught (at degree level) that this was trivial nomenclature and the only IUPAC nomenclature was the "x-oxy-y" type, such as "methoxyethane" - please correct me if I'm wrong, but I'm going to do a bit of research and find out, and possibly edit the article if I'm right - ta :) edd 08:33, 5 Jul 2004 (UTC)
should this be a disambig page?
what do people think? a discussion of diethly ether belongs on a separate page to discussion of ether's in general... jsut a thought... Erich 06:38, 15 Jul 2004 (UTC)
Williamson ether synthesis
The equation given for the Williamson ether synthesis shows an alkyl halide as a reactant, but what follows gives sulfonate esters as an example of a leaving group. Either the equation is not general enough or this example is incorrect. Josh Cherry 15:53, 26 Dec 2004 (UTC)
Should some mention be made of early astronomical/astrological claims of space consisting of heavenly bodies suspended in "ether?" 188.8.131.52 17:29, 14 November 2005 (UTC)
What came first?
If the known chemical was named after the ancient concept of "ether" or "aether", being what fills the void, or the universal solvent, then shouldn't this be the main entry for the word "ether"? All other entries may branch from this one. The article makes no mention of the ethymology of the chemical. Odraxir 00:17, 30 December 2005 (UTC)
The problem is that most of the article is relevant to chemistry alone and to include every association with "ether" will make it confusing to read. As wil alcohol , maybe a "Chemistry of.." page is better and to help produce a whole new specialist chemical section.
- the image on the ether page is technically a hemiaminal but the distinction is not always made. I have no objections against the current image V8rik 17:54, 18 August 2007 (UTC)
Needs a message that directs people to the Ether of classic physics
I think there needs to be a message that says something along the line of "for the Ether in classic physics that is believed to be the medium of which light travels, see [link]" at the top. RegalStar (talk) 21:28, 16 January 2008 (UTC)
- Isn't it enough with the link to the disambiguation page that is already at the top of the article? --Itub (talk) 09:34, 17 January 2008 (UTC)
Origin of name
Why are they called ethers? Did early chemists believe these newly discovered substances were the "aether" (either the luminifarious one or the Fifth Element), or is it more complicated than that? Daibhid C (talk) 21:22, 6 June 2008 (UTC)
That picture is massive
- Which one? There are sixteen images in this article at present.
The one that appeared in previous versions of the article such as here:http://en.wikipedia.org/w/index.php?title=Ether&direction=next&oldid=240861814 . Worth a look. You can't miss it. Meltyman (talk) 23:59, 2 October 2008 (UTC)
- I think this edit was enough to fix the problem.
- I'd prefer to undo this revision by Meltyman because the image is now too small to read easily.
I re-sized the image in the commons and then put it in a frame rather than a thumbnail in the article, i.e. pic on page is now actual size but that actual size is a fraction of the actual size of the previous image. This edit was OK but it bled into the next section a bit, I thought. Meltyman (talk) 19:54, 3 October 2008 (UTC)
- It's legible now but it's the aspect ratio has changed so the image is stretched. Ask the original author to recreate it in the required shape.
The aspect ratio has changed and the image has been stretched, but neither change is important to the understanding of the article or to the ease with which it can be read. It could look better but it's far from the mess that prompted me to edit this article in the first place. If the current edit bothers you, you might try following your own orders. Meltyman (talk) 23:00, 3 October 2008 (UTC)
If Dibutyl Ether is going to redirect to this page, then there should be more info on it in the article. Boiling point, structure, etc. —Preceding unsigned comment added by 184.108.40.206 (talk) 14:50, 29 July 2009 (UTC)
Possible error in page, at least an inconsistency?
In the 'Structure and bonding' section the C-O-C bond angle is said to be about 120 degrees. In the 'Physical Properties' section it is said the C-O-C bond angle is about 110 degrees. I believe it's exactly 109.5 degrees because of the sp3 hybridization, but I'm just a first semester o-chem student so wanted someone to verify this error before correcting it. —Preceding unsigned comment added by Jusmai77 (talk • contribs) 18:39, 21 January 2010 (UTC)
- The average bond angle in sp3 hybridization is 109.5 degrees, but in practice this is not always the case. Note that water is 104.5 degrees even though it is sp3 hybridized. This is due to the fact that the lone pairs take up more space than the hydrides. Intermolecular forces and intramolecular forces must also be considered. As it happens, I modeled a couple molecules with ether groups on avogadro, and found that the optimization produced angles between 110 and 115 degrees. CH3CH2OCH2CH3 had an angle of 113.2, and CH3CH2OCH2CH2OCH2CH3 had an angle of 111.4. Adam.braley (talk) 16:55, 28 October 2010 (UTC)
Polyethers: is it fair to refer to crown ethers as polyethers?
I'm not at all confident that the initial explanation of polyethers is accurate. Polyethers are definitely NOT molecules with multiple ether groups, they are polymers that contain repeating ether groups from their propagated monomers. What I'm not sure of is whether it's fair to call crown ethers polyethers. My instinct is no, but I can't back it up since I don't "know" that large crown ethers aren't synthesized by polymerization techniques. I doubt it, since neither step reaction polymerization nor chain reaction polymerization makes any sense for them as far as I can see. Anyway, I submit the question to you my fellow Wikipedians.Adam.braley (talk) 16:51, 28 October 2010 (UTC)
I changed the general formula to R-O-R'. This is consistent with the picture but the online iupac goldbook reference uses R-O-R. A different references that alludes to both R-O-R and R-O-R' is http://docs.google.com/viewer?a=v&q=cache:C8gFvmb-ls8J:chemistry.csudh.edu/faculty/jim/ethers.ppt+ethers+ror&hl=en&gl=us&pid=bl&srcid=ADGEESgZXYBidUi-rktMmIlMZnRmQLeFV_-PZPgdYkNNV-PeAPl7RpK7vAu9kLE9cHGRYmdNCH7413us4yOepqxtM0JwQcOqISSD6Q4KpJr3cyRhmGAOPW0zYSiQraRmmifCPB_hqOke&sig=AHIEtbTm3E1O2QEz8jxkVdlvAayTicHpGQ which is a google view version of http://chemistry.csudh.edu/faculty/jim/ethers.ppt
I think some clarification is needed about how the tendency of ethers to form explosive peroxides depends on their structure. The Sept 20th, 2011 version of this section in the ether article contained the statement "Primary and secondary ethers with a CH group next to the ether oxygen form peroxides....For this reason, diisopropyl ether and THF are often avoided as solvents.".
All the common ethers, including diethyl ether, tetrahydrofuran (THF) and diisopropyl ether contain a CH group adjacent to the oxygen. The first two are primary ethers containing CH2 groups adjacent to the oxygen, while diisopropyl ether is a secondary ether. THF and diethyl ether are very widely used as solvents, with precautions recommended such as storing in the dark and not distilling to dryness because of the danger of peroxides. The article diisopropyl ether says it is more prone to peroxide formation than diethyl ether, and less so than methyl t-butyl ether (MTBE). To totally avoid a CH group adjacent to the oxygen one would need to go a highly hindered (crowded) compound such as bis (t-butyl) ether, which may be too hindered to even exist as a stable compound.
Pending further clarification of the relation of peroxide formation to structure, I will change the text in the main article to say simply that ethers are susceptible to forming explosive peroxides, unless appropriate precautions are taken.CharlesHBennett (talk) 20:49, 20 September 2011 (UTC)
