In accordance with Wikipedia:WikiProject_Drugs naming policy, I propose we move this page to the INN pentaerithrityl tetranitrate. If you have any concern with this proposal, please discuss it on this page. Matt 17:39, 24 Dec 2004 (UTC)
I know chemists may like this diagram but the casual observer wont see all the elements. Why is this? —Preceding unsigned comment added by 69.154.23.3 ( talk) 06:27, 16 March 2011 (UTC)
I noticed that 63.162.143.5 deleted the section on production...I think it should stay deleted, instructions on making explosives do not belong in an encyclopedia. SCHZMO ✍ 21:33, 16 June 2006 (UTC)
"Charges manufactured in the future may include other explosives." Is this line helpful?
According to the Financial Times, December 28, 2009, Page 5. PETN "was also used by a would-be assassin of Prince Mohammed bin Nayef, Saudi Arabia's anti-terrorism chief, who was slightly wounded in August (2009) when the assailant exploded a device hidden in his underwear." If someone wants to add this to the main article, then it's fine with me. —Preceding unsigned comment added by Eroche ( talk • contribs) 17:49, 28 December 2009 (UTC)
What is the specific energy of PETN in MJ / kg or TNT equivalents? Shouldn't this be part of every explosives infobox?-- SiriusB 11:08, 26 September 2007 (UTC)
From the article:
On the surface, to a layperson, this appears contradictory. The mere fact that it does not occur naturally does not make it an environmental contaminant. Elemental calcium for instance does not occur naturally but is not an environmental problem. If the substance biodegrades readily, one would not ordinarily expect it to be problematic as a contaminant. Some kind of explanation is needed. Does it degrade into harmful contaminants? If so, what? If not, then what is the problem? This needs to be stated. —Preceding unsigned comment added by 66.213.116.12 ( talk) 14:09, 6 December 2007 (UTC)
You mean, in line 5: not "necessarily" an environmental contaminant. But, you are right. 68.231.189.108 ( talk) 12:49, 9 October 2009 (UTC)
Yeah that is a non sequitur. I'm removing it. If someone wants to put it back rewrite it so that the point is clear and source it properly. Enemyunknown ( talk) 05:33, 22 July 2008 (UTC)
MSDS materials are generally extremely weak on disposal/destruction of wastes associated with chemicals. It would be good to have accurate and quantifiable information regarding the degradation of this compound in the environment. This may need to also include hazardous byproducts created as a result of action with soils, air, water, ans sunlight. Military files created from demolition and disposal of weapons arsenals may be a good source to locate some of this information. Envengchem ( talk) 15:14, 27 December 2009 (UTC)

What is this "Penthrite" mentioned? Is this a misspelling? 68.231.189.108 ( talk) 12:46, 9 October 2009 (UTC)
I removed the following text from the lede, as it is inconsequential and too specific:
Dr. Greg Dicinoski of the University of Tasmania is working on creating a small portable unit that will detect the plastic explosive. [1]
If there's something special about how PETN can be detected or its (non)detectability, this might merit mention under such a heading. 173.70.24.75 ( talk) 18:00, 12 January 2010 (UTC)
I'm not sure (not having checked) if this is due to your revisions, but while ref'd language was deleted (which may be OK in the broad scheme), it was replaced with unreferenced statements that may or may not be true, but certainly require references to remain. For example, "Many technologies can be used to detect PETN" and "it belongs to a family of common nitrate-based explosive chemicals which can often be detected by the same tests" and "This is, however, not an exhaustive list." All of those statements need refs, or should be deleted -- its not appropriate (you've made few edits to Wikipedia, I recognize, so may not be aware of this) for editors to just write what they themselves "know" to be true, without reference to a reliable source.-- Epeefleche ( talk) 08:14, 14 January 2010 (UTC)
It strikes me that this section contains far to much information about the 2010 cargo plane bomb plot. I motion to delete all the material from "Both packages contained sophisticate" to "identified the bomb either.". NickCT ( talk) 16:33, 4 November 2010 (UTC)
"PETN is difficult to detect in terrorist incidents because..." kind of implies that it is somehow not so difficult if there are no terrorists involved. I'm not sure that terrorism needs to be highlighted here, but definitely think this sentence needs to be worded better if it is to remain. Can't think of the best way to do that at the moment, so looking for suggestions. wjemather bigissue 00:45, 8 November 2010 (UTC)
Under Explosive use, the third paragraph begins
This looks as if it was carelessly edited down from some more detailed text. As it stands, the second sentence is almost meaningless. I see two problems:

Bibliography no 15 don't work. Google Cache and at url http://easycaptures.com/fs/uploaded/565/5890511956.png is copy —Preceding unsigned comment added by 82.160.246.71 ( talk) 17:49, 31 December 2010 (UTC)
Non-relevant. Firstly, its already described in corresponding articles. Second, if it has some origin nature, can be motive for creating new article, not overhelming existing. Sanaris ( talk) 20:25, 9 May 2011 (UTC)
Hans Michels, professor of safety engineering at University College London, told a newspaper that 6 grams (0.21 oz) of PETN—"around 50 times less than was used—would be enough to blast a hole in a metal plate twice the thickness of an aircraft's skin".[37] In contrast, according to an experiment conducted by a BBC documentary team designed to simulate Abdulmutallab's Christmas Day bombing, using a Boeing 747 airplane, even 80 grams of PETN was not sufficient to materially damage the airplane's fuselage.
The article states that pentaerythritol tetranitrate was first prepared by Bernard Tollens and P. Wigand in 1891. I have read the reference that was cited — B. Tollens and P.Wigand (1891) "Ueber den Penta-Erythrit, einen aus Formaldehyd und Acetaldehyd synthetisch hergestellten vierwerthigen Alkohol" (On pentaerythritol, a quaternary alcohol synthetically produced from formaldehyde and acetaldehyde), Annalen der Chemie, 265 : 316-340. — and I found no mention of the reaction of pentaerythritol with nitric acid (although there was a mention of the reaction of pentaerythritol with acetic acid).
According to these sources:
PETN was first prepared by the German explosives manufacturer Rheinisch-Westfalische Sprengstoff A.G. and patented in 1894 (Deutsches Reichspatent 81,664). I am therefore correcting the article accordingly. VexorAbVikipædia ( talk) 13:50, 10 July 2015 (UTC)
