use

ethyl acetate is widely used in paint industry especially for manufacturing of thinner. since E.A. is hygroscopic in nature it can absorb moisture from air. does this encounter any problem ? If it is causing problems is there any solution for the same? 59.163.176.11 09:23, 2 October 2005 (UTC)

Chemical Name

It is listed here as "acetic acid ethyl ester". That is a common name, but since "chemical name" links to the IUPAC nomenclature article, shouldn't it use the IUPAC name, which I believe to be ethyl ethanoate? This would remain in line, of course, with IUPAC's preference of eth- over acet-,—ethanal against acetaldehyde, ethanoic acid over acetic acid, and so forth.

Of course, we'll still always refer to it as ethyl acetate, no matter what IUPAC says. — Doshea3 21:15, 9 July 2005 (UTC)

Actually, ethyl acetate is a IUPAC name (so is ethyl ethanoate). Since the former is the IUPAC name in common use, we use it here. See Wikipedia:Naming_conventions_(chemistry) (this page is currently under revision, but is now nearly finished and is pretty clear). We need to update the IUPAC nomenclature page somewhat.

Ah, misunderstanding—thanks for clearing that up; I shall now say proudly to whomever corrects me that ethyl acetate is actually IUPAC's preferred name. But my point is that wouldn't the IUPAC name (ethyl acetate, I presume now, over ethyl ethanoate) be better in the slot for chemical name than "acetic acid ethyl ester"? — Doshea3 00:49, 12 July 2005 (UTC)

The IUPAC does NOT (and probably never did, afaik) prefer ethanoic over acetic (and so on), see [1] for a list of recommended trivial names. Ethyl acetate IS the oficial IUPAC recommendation, see [2]. Cacycle 13:38, 13 July 2005 (UTC)

Oops, I was replying to an old version... Anyway. Cacycle

10/17: What's going on with the properties? It says it is a highly polar, weak solvent, then it says it is a non to weakly polar fair solvent. ???

I was wondering the same thing. Can someone clear that up? How can a moecule be "fairly polar" and "non-polar." I'm not sure which is more correct. --Michael 00:47, 25 October 2006 (UTC)

references

I've added references to this page for the catalytic conversion process but haven't worked out the citation template yet. I'll have a read but feel free to tidy the references into citations. —Preceding unsigned comment added by 172.209.66.143 (talk) 15:32, 24 September 2007 (UTC)

If you drink it?

Does itmake you drunk? —Preceding unsigned comment added by 202.161.1.55 (talk) 06:17, 7 November 2007 (UTC)

Maybe, but I wouldn't recommend it. ;-) It seems plausible that it could hydrolyze to ethanol and acetic acid in your body, and the ethanol would then make you drunk. I don't know about the physiological effects of ethyl acetate itself. --Itub 18:03, 8 November 2007 (UTC)

Pear or Tear

In the introduction, the chemical is described as having a smell similar to "pear drops". Was this meant to read "tear drops"? I have certainly never heard of pear drops, but I will withhold action because I do not think ethyl acetate smells like tear drops. 69.253.29.7 (talk) 00:51, 20 December 2007 (UTC)

My mistake - I looked it up and "pear drops" makes complete sense. Whoops. 69.253.29.7 (talk) 01:37, 20 December 2007 (UTC)

*Most* common chromatography solvent?

I think this one seriously needs a reference. I use chromatography on a daily basis, and although we do use ethyl acetate for some methods, it is by far not the *most* common solvent. We also regularly use chloroform, chlorobutane, ethanol, and a number of other solvents. I highly doubt that ethyl acetate is the most common, considering how many other solvents are frequently used. 206.194.127.112 (talk) 20:16, 5 September 2008 (UTC)
