[edit] Something wrong

The history page claims "ethanolamonium nitrate" (is it misspelled ethylamonium, or is it something different?) has a melting point of 52-55C. Later it shows the structure of ethylamonium nitrate, claiming its melting point to be 12C , but on the ethylamonium nitrate page it is given as 34C.

Something is not right. —Preceding unsigned comment added by 130.225.100.170 (talk) 09:57, 31 March 2008 (UTC)


[edit] Bio Ionic

Someone must do a Wikipedia article on Bio Ionic.

[edit] added

I've added two paragraphs - one on solubility and one on exceptions to the generally accepted behaviour of ionic liquids. In order to fit these paragraphs into the text I have also made some, in my opinion, minor changes to the existing text. Hopefully I haven't made too much of a mess, but I'd appreciate if someone would check it.

I also feel that the list over "Leading" (now "Major") academic groups is somewhat biased towards research groups in English-speaking countries, which in fairness may be due to Seddon's influence. I would like this to be addressed in the future, with the inclusion of Héléne Olivier-Bourbigou and nobel laureate Yves Chauvin, as well as possibly some of the Chinese groups that are beginning to make themselves known. --Caohlin 04:07, 26 February 2006 (UTC)

[edit] deleted

The "Suppliers" have been deleted, because there is absolutely now value. It's not clear if these ads are paid or not. Or we may list "Suppliers" everywhere ?

There was a stubby page titled "Ionic liquids" that I have redirected to this page. The previous content of that page is as follows:

Ionic Liquids are a class of ionic materials that are liquids at temperatures below 100°C. These ionic liquids can be made from uncountable combinations of organic and non-organic cations and anions. These ionic liquids are conductive and some can have some solubility for solid compounds that are solid due to hydrogen bonding, such as cellulose. Cellulose can be solublized up to 20% in the ideal ionic liquid. Any water present in cellulose and ionic liqid must be eliminated for there to be solubility.

If anyone can incorporate any of this information into "Ionic liquid," please do so. Tomgally 07:33, 11 Jun 2005 (UTC)

[edit] VOC

What's "VOC"? 212.201.44.249 12:23, 24 August 2005 (UTC)

[edit] toxic

I added the bit about aquatic toxicity, my research group currently is testing them, if I can I'll put up some of our relevant citations Helluo 05:13, 27 November 2005 (UTC).

[edit] historical context

Shouldn't the article have something about the history of these materials; who discovered them, and how? -- Cimon avaro; on a pogostick. 16:29, 5 March 2006 (UTC)

I've added a wee bit on the background. However, one should probably add better references on the origin and applications of haloaluminate ionic liquids. Or I'll do it when I can find more time. --Caohlin 15:18, 6 March 2006 (UTC)

[edit] Unit conventions

People have added a space between the degree symbol and the temperature at least twice now. The convention, at least when submitting scientific articles, is that there is no space before nor after i.e. "34°C" is correct, whereas "34 °C" is 'incorrect'. --Caohlin 08:28, 17 May 2006 (UTC)

[edit] Ambiguity

"The influence of the group of Kenneth Seddon at Queen's university, Belfast, which has now turned into the first research centre dedicated to ionic liquids, QUILL, should also not be underestimated."

Does that mean anything? I'm not sure why this was added, if it has value because of the direction that this specific group is taking research in the field, perhaps that direction should be noted.

AndoSEKleton 16:27, 17 May 2006 (UTC)

The intention was to underline the importance of Seddon in a historical sense - it's my understanding that he spent a lot of time in the mid-late 90's attending conferences talking about ionic liquids. Also, a number of researchers active in the field have at one point been associated with his group or attribute the origin of their interest in ionic liquids to discussions with him such as Tom Welton (and via him, Paul J Dyson), Robin D. Rogers and John D. Holbrey. --Caohlin

I absolutely agree that this is worth noting in the article, I just think that a fuller explanation (such as the above) is more useful to and tonally consistent with the rest of the article. AndoSEKleton 18:34, 22 May 2006 (UTC)

[edit] imidazolium ionic liquid

During some lab work I've achieved some confusing results. For instance when diethyl acetilenedicarboxylate and [1-hexyl-3-methylimidazolium][BF4] are mixed together, the solution colour changes from orange to dark red. Is this to be expected? Does it have anything to do with conjugation enhancement? or something just went wrong?

Imidazolium salts are colourless when pure. I suspect the intial colour was due to an impurity, and this impurity reacted with the alkyne to give you the red colour.

[edit] Hydronium bisulfate?

Surely equimolar solutions of water and sulfuric acid or nitric acid were known long before the compounds discussed in this article? Why are they not considered ionic liquids? --Atemperman (talk) 19:11, 7 April 2008 (UTC)
