[edit] Usage section (dye) cleanup

I have redirected the article Aniline dye to this article, since the entire amount of material to be merged (quoted below) was quite brief; the last sentence is misleading if not actually completely incorrect.

"Aniline is a chemical that is a by product of burning coal. The first synthetic dye (mauve, developed in 1856) was a coal tar product and contained the chemical aniline but the term "aniline" has been used to include other chemical type dyes. Today the term "aniline" is used mainly to differentiate natural dyes from the synthetic dyes."

The usage section needs a copyedit and cleanup; I haven't got time right now, but I might get around to it if nobody else does.

  • This looks like a section from the 1911 Britannica: it is not accurate today! Physchim62 00:01, 25 August 2005 (UTC)
  • This article looks like its been cleaned up now, right? It's still listed on the chem portal front page as needing cleaning up user:austinbooth 20:49, 13 January 2005


[edit] Solubility in water?

It says miscible, that can't be right, can it?

You're right; it's wrong. This site says 3.6 g/100 mL at 20 °C. The other solubility entries (miscible in ethanol and acetone) are correct, according to my CRC Handbook. Good catch. TenOfAllTrades(talk) 17:58, 1 March 2006 (UTC)

[edit] products of combustion

Does anyone know the products of combustion, and products of incomplete combustion for aniline?

Complete combustion will produce water, carbon dioxide and nitrogen dioxide. Ammonia is quoted here as a possible product of incomplete combustion, although I would still think that it is the nitrogen dioxide which would be the highest risk, not to mention unburnt aniline vapor.

[edit] Safety Data will have to go

Wiki is not a repository for safety data, the references should suffice. propose to axe this section V8rik 19:32, 11 August 2006 (UTC)

Agreed, section is a goner, links should be enough (or find it yourself in Wikipedia:Chemical sources). --Dirk Beetstra T C 21:03, 11 August 2006 (UTC)

You two should look at hydrazine, which I have started to revise slightly.--Smokefoot 23:12, 11 August 2006 (UTC)

Which safety data are you talking about? The presentation seems fairly standard to me. Physchim62 (talk) 14:21, 12 August 2006 (UTC)
I see it now, yes, that sort of section should go: it could be placed on the data page if anyone really wanted to, but not in the article. Links to commercial MSDS pose the same sort of problem as Wikipedia:Chemical sources, although there is a dedicated section on the data page if anyone ever used it! Physchim62 (talk) 14:25, 12 August 2006 (UTC)

It should just not be here, bit too much of a risk giving wrong data. Same goes indeed for single MSDS links. They are biased. On Wikipedia:Chemical sources at least one can choose one .. if ever it would get to functionality (if it gets used is then a second question). But I think it is a good plan to keep savery data to a minimum, and preferably referenced. --Dirk Beetstra T C 17:15, 13 August 2006 (UTC)
