So Long TNT, There's a New Explosive in Town

I&#x27;m surprised that this is being compared to TNT. I was (naively, maybe) under the assumption that weapons moved away from TNT already since long time - to HMX and RDX, mostly, which should be already 50-60 years old.<p>Also - at 8.18km&#x2F;s detonation velocity, this thing isn&#x27;t even so exciting.<p>Hexanitrohexaazaisowurtzitane has much better performance, higher density, a cooler name :-), seems to be reasonably practical to produce&#x2F;handle (at least as far as high explosives go), and is a fantastic excuse to link to Derek Lowe&#x27;s eminently enjoyable &quot;Things I won&#x27;t work with&quot; articles: <a href="http:&#x2F;&#x2F;blogs.sciencemag.org&#x2F;pipeline&#x2F;archives&#x2F;2011&#x2F;11&#x2F;11&#x2F;things_i_wont_work_with_hexanitrohexaazaisowurtzitane" rel="nofollow">http:&#x2F;&#x2F;blogs.sciencemag.org&#x2F;pipeline&#x2F;archives&#x2F;2011&#x2F;11&#x2F;11&#x2F;thi...</a>

Popular Mechanics is not great for people with more than the bare minimum knowledge of chemistry. The new explosive is bis(1,2,4-oxadiazole)bis(methylene)dinitrate:<p><pre><code> ONO2 &#x2F; H2C \ C---O &#x2F;&#x2F; \ N N \ &#x2F;&#x2F; \ &#x2F;&#x2F; C | C &#x2F;&#x2F; \ &#x2F;&#x2F; \ N N \ &#x2F;&#x2F; O---C \ CH2 &#x2F; O2NO </code></pre> I propose the acronym &quot;BODAMN&quot; (Bis Oxa-Di-Azole Methylene Nitrate), as the one most likely to catch on among those melt-casting it. Army folks love pronounceable acronyms.<p>In the absence of sufficient oxygen, reaction products are likely to be<p>C6H4N6O8 --&gt; 3 N2 + 2 H2O + 6 CO<p>C6H4N6O8 --&gt; 3 N2 + H2O + H2 + CO2 + 5 CO<p>C6H4N6O8 --&gt; 3 N2 + 2 H2 + 2 CO2 + 4 CO<p>That beats TNT, which produces between 1 and 3.5 moles of C (as soot) per mole of TNT. With BODAMN&#x27;s all-gaseous products, the hot CO and H2 can expand after the initial detonation, and then react with O2 whenever they can find one.<p>With excess oxygen available, the hot, pressurized N2 might also form some NO or NO2.

Related fun fact: Dynamite was invented by Alfred Bernhard Nobel.<p>Nobel didn&#x27;t want his legacy to be one of destruction, so he founded the Nobel prizes that are still awarded today.

Is TNT even widely used anymore? There&#x27;s far more stable&#x2F;safer to handle explosives. I&#x27;d have assumed TNT was largely abandoned in the developed world.

Not sure how &quot;TNT, or trinitrotoluene, is a mixture of the seemingly innocent elements carbon, hydrogen, nitrogen, and oxygen&quot; made it past the editor. TNT is a compound, not a mixture. And nitrogen isn&#x27;t innocent, it&#x27;s notorious for being in tons of explosives.

What are they actually going to call it? Bis-isoxazole is a mouthful. If people are afraid to talk about it for fear of mispronouncing it and looking foolish, will it see commercial success?

I love the TNT (the courier) ads that appear on the page (at least in my browser). So much for the sophisticated AI.
