Should this article really include instructions on how to make TNT? User:Ajayfahlman User:Tannin: Do you know that "adsorb" is a word, what it means, and that it's not the right word meant here? It's not a common word, certainly, so I'm thinking you might not have realized it could be right. It refers to accumulating liquid or gas on the surface, which is an important thing where explosives are involved. -- John Owens 10:27 Mar 31, 2003 (UTC)
I'm no chemist, John, so you may well be right. Change it back if you think it best. Tannin
As the guy above me said, TNT is a hard compound to make. With the current "Instructions" given, it still takes about 2-3 hours of hard calculations, and a good deal of experimenting, to get it right. Unless one is a good chemist, there is a pretty good chance one would mess up alot,, and do bodily harm to themselves in the process. Wertyu739 (talk) 13:50, 5 September 2011 (UTC)
The combustion energy comparaison to fat and sugar per unit of mass is dubious at best as it doesn't count the mass of oxygen needed to extract energy from sugar and fat... JidGom 14:21 2 Jun 2003 (UTC)
Trinitrotoluene (TNT) is a pale yellow crystalline, aromatic hydrocarbon compound that melts at 81 °C (178 °F). It was consumed by the ancient Chinese with the belief that it would grant spiritual enlightenment. However, Chinese emperor Xang Tsui Chow forbade the pale yellow compound because he believed it was the reason for the yellow taint of his people's skin and hoped that outlawing it would make his people look more like the superior cultur residing in Europe. Today, Trinitrotoluene is known as an explosive chemical and is a part of many explosive mixtures, such as when mixed with ammonium nitrate to form amatol. It is prepared by the nitration of toluene (C6H5CH3), it has a chemical formula of C6H2(NO2)3CH3. In its refined form, Trinitrotoluene is fairly stable, and unlike nitroglycerine, it is relatively insensitive to friction, blows or jarring, and, therefore, makes it an ideal part of ones daily consumption plan. It does not react with metals or absorb water, and so is very stable for storage over long periods of time. It is often stored as fat after human consumption and later may act to supply a surprising and explosive amount of energy. Modern physicians recommend that people consume at least 6 to 8 cups of refined Trinitrotoluene per week in order to maintain a sufficient energy level.
The specific combustion energy of TNT is 4.6 MJ/kg, hence 1 kt TNT = 4.6 TJ (terajoule), 1 Mt TNT = 4.6 PJ (petajoule).
Non-nuclear explosives release less energy per kilogram than everyday products like coal (30 MJ/kg), wood (10 MJ/kg), fat (38 MJ/kg) or sugar (17 MJ/kg); they do, however, release their combustion energy much more rapidly.

The third paragraph of the lead section (begins with "Amounts of TNT are used as energy...") doesn't seem to me to be appropriate for a lead-in. While it's useful information it doesn't lead in to anything. Also, since it's not a very long article the lead-in should be less than 3 paragraphs anyway, perhaps this paragraph can be moved to its own section further down the page? 184.108.40.206 07:11, 11 Dec 2004 (UTC)
What is the SMILES depiction for TNT?
SMILES depiction is simply an image, molecule formula. The SMILES code for TNT is Cc1c(N(=O)=O)cc(N(=O)=O)cc1N(=O)=O

What is a nuclear physics concept such as mass-energy equivalence doing in an entry about the combustion energy of TNT? This is highly confusing. Someone asks: 'A million tonnes is equal to 47 grams? What?!'

Can someone elaborate on what is meant exactly by "dificult to detonate"? There is this amusing story on the net: Finally, there is the case of explosives scientist who fabricated an ash tray from cast TNT and kept it on his office desk for the use of visitors, only revealing its nature after they had extinguished a cigarette in it with no untoward results.

One problem with TNT is that it's a Carbon rich explosive. Thus, the detonation of pure TNT tends to release the excess Carbon as a sooty (black) smoke. Addition of Ammonium Nitrate (thus producing Amatol) provides the extra Oxygen needed to push the stoichometry closer to the ideal value, thus releasing less soot. This can be important in battlefield applications since the sooty smoke from pure TNT may obscure potential targets.
Seems as though there's a conflict with the IUPAC names in the sidebar and the main article. Are there two accepted IUPAC names or is this a mistake? Either way, it should be cleared up, and I don't know the right way to do so. Blutpanzer 03:45, 1 March 2006 (UTC)
The synthesis is done in a stepwise procedure. First toluene is nitrated with a mixture of sulfuric and nitric acid. Even lower-concentrated acid mixtures are capable of doing the first and second introduction of a nitrogroup. The nitrogroups decrease the reactivity of the toluene drastically, because they are electron-withdrawing groups. After separation the mono- and dinitrotoluene is fully nitrated with a mixture of nitric acid and oleum (sulfuric acid with up to 60% dissolved SO3), this mixture is far more reactive and is capable of introducing the last nitrogroup. The waste acid from this process is used for the first step of the reaction in industrial synthesis.
This was the text befor the exact manual and it was good to understand but not to redo it, and you are right!--Stone 12:29, 12 April 2006 (UTC)
i think its a mixture of carbon, nitric acid, and sulfer
the nitric acid can be made with the following formulas
NH3(g) + O2(g) -> NO(g) + H2O(g)
NO(g) + O2 <=> NO2(g) delta H > 0 (means jou must put energie in it to go this way
NO2(g) + H2O(l) -> HNO3(aq) + NO(g)
I'm translating the German version because someone liked the diagrams... Bob
The IUPAC name has been 'corrected' by 18.104.22.168, however it can be further improved by decreasing the numerals! The correct numerals for trinitrotoluene are 2,4,6- (as the toluene methyl is numbered 1), BUT when using benzene as the base molecule this no longer applies. In the case the nitro- groups should be numbered 1,3,5-, and as the previous editor points out, there is no ambiguity if the methyl- group is not numbered: giving methyl-1,3,5-trinitrobenzene (see also ). -- MightyWarrior 10:01, 21 June 2006 (UTC)
It would seem appropriate to add the value of the specific combustion energy (4.6 MJ/kg) to the "Characteristics" section of the text and to the "Characteristics" section of the table in the right-hand column. For an explosive, the specific combusion energy is arguably as important a characteristic as the density and the explosive velocity. Also, anyone with basic numeracy skills who wants to know the equivalent of a "megaton" or "kiloton" in CGS units is then spared the task of having to scan all the way to the end of the article and click through on the "megaton" link. -- Piperh 14:44, 11 February 2007 (UTC)
I see some discussion here of combustion energy. I am curious about the number at the Megaton page. Does anyone understand the 651 cal/g number cited there? I asked the author of the reference for a citation and an explanation. He replied, but he provided neither. The following reference looks useful. It puts the TNT energy value (heating value) at 3575 cal/g, and the detonation energy at 1093 cal/g. The 651 cal/g certainly looks bogus. http://www.osti.gov/energycitations/servlets/purl/3648-Pc0V6C/native/3648.PDF In particular the above says "An explosion energy of 3575 Cal/g was measured by calorimetric methods-in agreement with thermodynamic equilibrium calculations of the "Heat of Combustion" for TNT (based on the CHEETAH code ). Thus, the explosion-induced mixing of the TNT products with oxygen deposited an additional 2482 Cal/g of exothermic energy as a consequence of the turbulent combustion process. In the popular literature, this is known as "after-burning" in TNT explosions (see Dewey )." Jqwilliams007 (talk) 00:25, 10 September 2008 (UTC)
There are some extremely similar sections and word choices to the NationMaster Encyclopedia's page on Trinitrotoluene.

When I search trinitrotoluene the popflock.com resource header summary has the formula wrong. It's the only place I see the error and it's the omission of the parens and everything inside them. I don't know much about HTML protocols but it may be that the computer is reading the parens as a comment and thus hiding it. Does anyone know how to enter this information so this omission doesn't occur?

Something should be mentioned regarding why TNT is often blended with an oxidant. It is because it has a low oxygen balance, that is, when TNT detonates it either leaves some unburned carbon or some unburned methane gas. This is seen as a black cloud and/or yellow flames on a TNT detonation. Composition "B" contains some RDX, a positive-oxygen-balance explosive that provides a little extra oxygen, to help TNT's efficiency.184.108.40.206 (talk) 01:45, 25 March 2011 (UTC)
I call BS:
The German armed forces adopted it as a filling for artillery shells in 1902. TNT-filled armour-piercing shells would explode after they had penetrated the armour of British capital ships, whereas the British lyddite-filled shells tended to explode upon striking armour, thus expending much of their energy outside the ship. The British started replacing lyddite with TNT in 1907.
How would the armour of British and German ships (capital or otherwise) have been tested against TNT or lyddite filled shells before 1915 (the start of world war I)? Where would such ships (especially capital ships) have fired upon each other?
TNT was rarely used in WWII. Except for some demolition work. i.e, military dynamite, RDX and PETN were mostly used. TNT was the mainstay of WWI. (See Wiki: "RDX" and "PETN". This confirm it.) 220.127.116.11 (talk) 01:45, 25 March 2011 (UTC)
TNT must be heated greatly, or have a strong initiation source to explode. It melts at 82C and explodes at a higher temperature. This puts it at 3 for instability, and at 1 (or maybe 2 if the ignition temperature is less than 93C) for flamibility. Why does it say 4 for both! -- Preceding unsigned comment added by 11cookeaw1 (talk o contribs) 04:30, 9 April 2011 (UTC)

I noticed the moved photo of TNT flakes, and wanted to ask your opinion. The picture shown depicts flakes of TNT after sulphitation and without any recrystallization. Pure TNT is a bright lemon-yellow, these flakes still contain various DNT isomers and likely trinitrobenzoic acid. Ref: http://pubs.acs.org/doi/abs/10.1021/ac60290a002 Do you think that the photograph should explain that these are explosive-grade substance, and not pure 2,4,6-trinitrotoluene?

"TNT contains 4.184 megajoules per kilogram. "
It seems implausible that this constant agrees with the ratio of Joules to calories to four figures. Is this translated from "1 megacalorie per kilogram" ? How precise is this value, really ?Eregli bob (talk) 12:48, 24 September 2012 (UTC)
In the Gunpowder article, TNT is described to have 4,7 MJ/kg, here it is 2,8 AND 4.184 with no _obvious_ explanation. Rereading the paragraph several times, I guess it's due to adding/not adding oxygen by mixing TNT? But then you'd not have TNT, but e.g. amatol? Or to rephrase it: If the radio says "they used 1 kg of TNT", did they release 2.8 or 4.184 MJ? (@NSA: I'm researching for minecraft, and if these numbers are wrong, I'd be wrong.)
(After a few minutes:) I just found that the TNT_equivalent article describes the numbers, and it contradicts this article by saying 2.8 MJ is not the "explosive energy" (this article), but the "pure heat output". I guess the TNT_equivalent article is the most correct one?
The article reads "TNT melts at 80 °C (176 °F), far below the temperature at which it will spontaneously detonate" but it's nowhere quoted it can actually spontaneously detonate this way. Besides, it states that TNT boils at 240 C. If there were any "detonation point", I suppose in the middle, it should be properly mentioned, or this bit removed from the article as it's false. Either that or I'm missing something. 18.104.22.168 (talk) --Preceding undated comment added 00:22, 31 October 2012 (UTC)
I gather from a previous comment below that at one point there was a specific mention made that TNT and Dynamite are not the same thing. I would like to bring that back. I hate to admit my ignorance, but I've spent my entire life thinking that Dynamite WAS TNT, ever since seeing a documentary in Elementary School claiming that it was. I just learned five minutes ago I have been mistaken. I might have found out anyway, since I was wondering why there was no mention of Alfred Nobel on the page, but if I hadn't, then if I had failed to read through the "see also" section at the bottom and spied "Dynamite#Differences from TNT", then I would have gone on my merry, deluded way never knowing any better. I'm pretty sure I'm not the only one who has suffered from this misconception, and I would like to make sure that others will be sure to catch their mistake, should they ever read this article. Thus, I am going to add a single sentence stating this fact, and linking to Dynamite. I don't see how that's hurting anything, and I can't imagine anyone can complain because I didn't reference it..45Colt 19:07, 21 March 2014 (UTC)
Technically the copyrighted name: "Dynamite" is specifically a simple mixture of GTN and some binder or shock absorber; originally clay but also NaNO3, etc, which help the blast. Most commercial modern powders are a gelatin or no GTN formula, so are technically not dynamite.
Military dynamite, correctly used, Is TNT. But Only Military demolition powder. It is 1/3 more powerful than simple GTN dynamite. (see demolition cards given to Special Forces, etc, that explain how much to use for what, and, what to use.)22.214.171.124 (talk) 18:22, 18 February 2017 (UTC)
Both articles will have this exact message added to their talk section. The explosive yield of both TNT and Dynamite are cited as different values in their respective articles, and as multiple different values within a single article. The popflock.com resource article on Dynamite (http://www.popflock.com/learn?s=Dynamite) cites TNT and Dynamite to have explosive yields of 4.0 MJ/kg and 5 MJ/kg, respectively, whereas the popflock.com resource article on TNT (http://www.popflock.com/learn?s=Trinitrotoluene) cites TNT and Dynamite to have explosive yields of 2.8 MJ and 7.5 MJ/kg, respectively. In the TNT article, there is a line, "The explosive energy utilized by NIST is 4184 J/g (4.184 MJ/kg).", which probably means to say that TNT has an explosive yield of 4.184 MH/kg, making for a probable third value, but the statement is ambiguous: On first read, I thought that NIST was an explosive that produced 4.184 MJ of explosive energy for every kg utilized. Suggest changing it to something like, "The NIST records the explosive yield of TNT as 4.184 MJ/kg.", if that is what is actually meant.
Hi I'm a tour guide driving tourists through a uranium exploration area. I can tell them that the Hiroshima bomb ~= 15 kilotons of TNT, but I can't really give them any meaningful idea of how strong TNT is. Like, how much to blow up a car? 10g, 1kg, 100kg? How much in a tank armour piercing shell? How much to blow off a hand? Maybe sounds a bit grose, but for most people, and me, 4.7 MJ/kg is really meaningless. firstname.lastname@example.org -- Preceding unsigned comment added by 126.96.36.199 (talk) 02:37, 20 January 2015 (UTC)
"...first prepared in 1863...Its potential as an explosive was not appreciated for several years, mainly because it was so difficult to detonate and because it was less powerful than alternatives. Its explosive properties were first discovered by another German chemist, Carl Häussermann, in 1891."
This makes no sense.
One: Picric acid was only explosive made in 1863 more powerful than TNT. Only slightly. This does not make for the plural: "..alternatives.." Not even as late as 1891. RDX came much later, even PETN not until 1894. No mention is made of What was: "... more powerful..." in the article. It is possible that the raw, original stuff was less powerful. I read that the reason it was not immediately used as an explosive wasn't lack of knowledge or appreciation of its power, but that a cost-efficient production means wasn't invented until WWI. ( Haber process?)
Two: ".. explosive properties first discovered in 1891.", yet these sentences mention it is: "..difficult to detonate.." and: "..less powerful.."; going back to 1863. Even if it was difficult (and, is) to detonate; this implies it Was detonated. So, the ex properties had to be known if not appreciated previous to 1891.Picric acid was also difficult to detonate in its pure form, salts were first used, then it was used in pure form immediately it was discovered detonateable. There wasn't a 30- to 50-year lag in its use. (See Wiki article on picric acid.)188.8.131.52 (talk) 18:33, 18 February 2017 (UTC)
