Talk:Azobisisobutyronitrile

Untitled
Could somebody please explain why this article should be merged with Azobisisobutylonitrile? I'm assuming for the moment that they are different compounds, although apparently related. Thanks. &mdash; RJH (talk) 14:47, 14 July 2006 (UTC)
 * Which article? Merge?  What?  This is the talkpage of Azobisisobutylonitrile, you cannot merge an article with itself.  Could you please specify?  --Dirk Beetstra T  C 15:15, 14 July 2006 (UTC)


 * I think there is a misunderstanding, the page on ABCN contains a merge proposal to this page (proposed by myself), the page barely contains data and the table is empty. Many other chemical compound pages contain information on related molecules, for example Lithium aluminium hydride has info on related red-al V8rik 15:24, 14 July 2006 (UTC)
 * Talk:ABCN has already been redirected here, which is quite improper. If the artiles are separate, cthe talk pages should be separate. I'm going to revert the redirect. --Bduke 01:22, 25 July 2006 (UTC)


 * I was told here that the merge would be a bad idea. The ikiroid (talk·desk·Advise me) 17:53, 25 July 2006 (UTC)

Can someone explain to me where this claim of AIBN exploding in acetone has come from? I can find no reference for this anywhere. 128.246.128.130 (talk) 15:16, 12 May 2009 (UTC)

The drawing
I'm pretty sure the decomposition of AIBN is stepwise, not concerted as shown in the current mechanism... —Preceding unsigned comment added by Peace and Chemistry (talk • contribs) 07:07, 6 May 2010 (UTC)

Shouldn't it just be a double bond between the two N´s? Instead of a tripple bond, and thats why its called azo... —The preceding unsigned comment was added by Christian75 (talk • contribs).

the above is fixed but another problem is the stoichimetry is wrong: the reaction produces two radical fragments —The preceding unsigned comment was added by 132.181.173.204 (talk • contribs).

Fixed. Take a look at WikiProject Chemistry/Image Request. --Rifleman 82 14:34, 19 December 2006 (UTC)

Spelling
The article title is spelled wrong, it should not be Azobisisobutylonitrile but Azobisisobutyronitrile since it's the most commonly used. A quick search on Google with each version will confirm this. -- Eugene 140.247.239.153 (talk) 01:33, 10 December 2007 (UTC)


 * Agree, name change is in order V8rik (talk) 16:59, 10 December 2007 (UTC)
 * Done and done. Looks like we had had the "r" spelling as a redirect to the "l" spelling, but I've never seen the "l" before in literature or chemical catalogs. DMacks (talk) 17:27, 10 December 2007 (UTC)

Name/Nomenclature
The compound should be named "azoisobutyronitrile" (no "bis"), which derives from "isobutyronitrile" and the divalent "azo"; it is old nomenclature, which is, nevertheless, defined by IUPAC: "Rule C-911. Azo compounds (Alternative to Rule C-912). 911.1 - Monoazo compounds RN=NR, in which the azo group -N=N- links radicals derived from parent molecules that, when unsubstituted, are identical, are named by adding the prefix "azo-" to the name of the unsubstituted parent molecule. Substituents are denoted in the usual way by prefixes and suffixes. The azo group has priority for lowest available numbers; one set of locants is distinguished by primes." (Nomenclature of Organic Chemistry, Sections A, B, C, D, E, F, and H, Pergamon Press, Oxford, 1979. Copyright 1979 IUPAC.)

For example: azomethane is Me-N=N-Me, azobenzene is Ph-N=N-Ph, there is no need for a "bis" or "di". —Preceding unsigned comment added by 134.130.101.232 (talk) 11:31, 11 May 2009 (UTC)

Safety
The safety risk phrases should be R2-R11-R20/22-R52/53 these can be checked on the sigma aldrich web page or in the msds which can be here http://www.sigmaaldrich.com/catalog/ProductDetail.do?lang=en&N4=11630|FLUKA&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC. I would say I think it is really important that the risk phrases are correct on chemicals as I know a number of young researchers have some what unwisely been known to rely on them. — Preceding unsigned comment added by Msrbbj (talk • contribs) 14:10, 18 June 2011 (UTC) The article implies that AIBN decomposes above 65 degrees C. It should read, "the half-life for AIBN is 10 hours at 64 degrees C." It will decompose, albeit more slowly, at lower temperatures, and does not instantaneously decompose at 65 degrees C.--Wmardis (talk) 12:49, 7 September 2012 (UTC)
