Talk:Aniline

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 elmo. 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.

See also the notes regarding aniline-based dyestuffs here. --TenOfAllTrades 21:46, 2 Feb 2005 (UTC)


 * 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

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 &deg;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)

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.

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 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 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 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)

making black?
what is the best way to make aniline black we are using potassium chlorate —Preceding unsigned comment added by 119.30.96.107 (talk) 06:07, 29 June 2008 (UTC)

Needs a redirect
At Coal dye, Coal tar dye, and probably others as well. ~ender 2008-10-05 5:52:AM MST
 * Done. -- Ed (Edgar181) 15:00, 5 October 2008 (UTC)

Rocket fuel
Aniline is hypergolic with RFNA (red fuming nitric acid) and the combination was used as a rocket fuel for JATO during WWII (Ignition, John Clark, p.21). Worth adding to the uses? Richard Gadsden (talk) 17:57, 4 November 2009 (UTC)


 * Yes, I would say so. Although an historical niche use, and while data on the current usage is of course important, minor uses in past times are of interest and use to non-technical lay readers. That, I suggest, is the very purpose of an encyclopaedia. To help the less-well informed. Wikipedia isn't a technical reference book for chemical engineers. It has to service the needs of others too.
 * I suggest something like this.
 * Aniline was used as a fuel with a RFNA oxidiser in the MGM-5 Corporal Surface-to-surface tactical missile fielded in considerable numbers by both the US Army and the British Army, principally in West Germany, and carried a W-7 atomic warhead; the first US missile to be nuclear-armed. It was broadly comparable in design and purpose with the Soviet Scud-A missile of similar vintage. Corporal was an important development as the first attempt by the United States in replacement of long-range artillery to suit the post-WW2 era. Very much a learning exercise, and was succeeded by a series of solid-fuelled missiles, easier and less hazardous for troops to handle. Considerable numbers were deployed and test fired by 10 US Army battalions and 2 British battalions, eight of them in Germany.
 * George.Hutchinson (talk) 18:01, 6 January 2017 (UTC)

It is also used as fuel in the Aerobee rocket's second stage engine.
 * About 2,000,000,000 kg of aniline are produced annually, according to the Ullmann Encyclopedia. So many niche apps that merely use a million or two kg will do not get a full discussion.--Smokefoot (talk) 18:14, 6 January 2017 (UTC)


 * Usage stats are only a part of the picture Smokefoot. Usage history is important too. Those who deny history an airing are doomed to repeat it's mistakes. Esp when the "million or two kg" had the power to bring civilisation as we know it to an end.
 * George.Hutchinson (talk) 14:45, 20 January 2017 (UTC)
 * Right. If we relied on usage stats, a lot of pharma etc would be dismissed as minor contributors to civilization because not many tons were produced compared to bulk apps.  It's a judgement call, and I am not the cop here.  I do know from experience that some editors seem to over-rate (my term) the significance of things that blow up.  It's a guy thing.  --Smokefoot (talk) 14:54, 20 January 2017 (UTC)


 * "A guy thing". Wonderful insult Smokefoot. How is it that when a contributor loses an arguement they feel a need to resort to a crude insult? Is that a guy thing too? George.Hutchinson

Suspected TYPO (or something like that)
The name of the section Aniline of this article contains the preposition "at". That word does not sound right to me. I don't think it would ever be used like that (in a context like this), by someone (e.g. a native speaker) who had a good knowledge of correct English language usage.

I think it should be changed -- probably to [something like] OR
 * "Reactions involving nitrogen"
 * "Reactions with substances containing nitrogen".

(Right?)

Any comments? --Mike Schwartz (talk) 00:50, 21 April 2015 (UTC)


 * It refers to the moiety, where the reaction takes place, i.e. the nitrogen atom in the aniline molecule. --Leyo 18:15, 21 April 2015 (UTC)

Physical characteristics
It is an oily liquid with pungent, musty fishy odour. It is colorless with a bluish fluorescence when freshly distilled and gets photo-oxidised on exposure to air and light becoming yellowish to brownish. -Shubjt 02:35, 13 February 2023 (UTC)
 * very good quote. But its colorless.--Smokefoot (talk) 03:54, 13 February 2023 (UTC)
