forming some sodium 5-NTZ. This is a pretty sensitive compound and must be treated with the respect it deserves! When dry this stuff is highly sensitive to impact flame and friction. Small amounts can cause great damage. it's synthesis is fairly straight forward involving PH changes to induce the formation of copper hydroxide and with heating to decompose this into copper oxide which is filtered off through celite. the resulting filtrate is acidified with HNO3 and is evaporated down to induce crystallization. the NaNTZ requires several re-crystallization steps from both water and acetone to yield a product pure enough for further synthesis into other 5-Nitrotetrazolate metal salts eg- silver, lead, cobalt/perchlorate complexes and the incredibly powerful mercury salt which is one of the most potent modern initiators known and has seen use by the US Naval force.
Thanks for another great video. Very BadAzz brother, as usual. Amazingly powerful compound. Working on NiNTZ. I couldn't find your CuNTZ video anymore. Did you remove it?
Cannagorilla Canna no. I’ll give you a link. Just private now. Also. Take care!!! These compounds are incredibly powerful and sensitive. Tiny amounts can do a lot of damage if set off in wantedly.
Cannagorilla Canna ok it will be public for a couple of hours so you can Download it or whatever.
AllChemystery thank you! Got it
Soon gonna restart my own lab
nice job！I failed to control PH to make NaNT from CuH(NT)3. but I found it more easy to get Ca(NT)2 because Ca(OH)2 have a low solubility to control PH
Why does it need to be acidified to pH 4?
Hi mate, again, love your channel, new subscriber! Anyway, these tetrazoles seem very interesting.
I've got a question regarding these: How good do you think tetrazoles would be as primers for gun cartridges?
I asked the guys from Explosions&Fire channel but they didn't really know much about guns in general, although they mentioned that tetrazoles would probably be "the future", but from seeing some tetrazoles in action they seem almost a bit "too good", if you know what I mean, since a gun primer generally isn't more than 0,5mm of brass, and I'm not really confident in putting the tetrazoles in there, from what I've seen so far, as a minuscule amount seems to blow holes on most metals LOL
Anyway, would be nice to hear what a pro has to say about it. IF tetrazoles could be used as gun primers, which tetrazole compound do you think would be the best, and would you be able to put it in there pure, without any risks, or would you have to mix it with something to make it more stable and less reactive/powerful?
Erik Persson perhaps they would pack a little too much punch for a bullet primer but certainly good enough for small initiator charges in a firing train. DBX-1 would probably be the choice if any. This is a nitrotetrazole formed with this NaNTZ and a copper I salt usually copper I chloride and this is "the future" Ex&F would be talking about. There's many others though and the worlds modern military researchers are investigating tetrazoles for so called green primaries which phase out lead and mercury compounds in favour of far less toxic and polluting primary explosives. It really is a big deal to them.
Hi mate, thanks for a great response!
So, what exactly is DBX-1? I tried searching on YouTube but it only gave me Dragon Ball Z episodes LOL
Yeah, I also agree with what you said, most tetrazoles I've seen so far would just blow the entire primer cap and probably the whole brass cartridge up as well :-O Although there should be some way of weakening/diluting the primer compound so as to make it a perfect mixture?
I definitely think that "green primaries" is a good idea, because I'm not really overly positive about having to use either mercury or lead to ignite my gun powder, and just multiply this with every gun owner in the world multiplied with every shot he's ever gonna make with a lead or mercury primer, and you've got yourself something which I don't really find that positive. I think these kind of compounds are out-dated and old-fashioned, made in a crude past when people still didn't know the long-term dangers of some chemicals. So I'm all into finding more environmentally friendly compounds, but also safer, AND stronger, (of course) ;-)
Anyway, it would be really awesome if you could try to come up with an idea of how to make a good stable primer, and then make a video of where you're making it. That would be incredibly helpful!
All the best mate,
Erik Persson the CuNTZ lol
Nice job.. I really love all your videos😘👍👍👍👍👍👌👌👌👌👌
How stable is this stuff in solution for long term storage?
As far is i know this is quite stable in ambient conditions. also Engager mentions this in his publication "Energetic Derivatives of Tetrazoles" that would be dry room temp i guess. there was no elaboration there.
Interesting side note on my first successful NaNTz production from the 2017 batch method.
Once the reaction was complete and I acidified and reduce the solution, the first precipitate I got was a lot of beautiful white thin crystals which crashed out at 16.4°C . I originally thought that this was the NaNTz but when I tested one of the crystals on aluminum foil with heat and nothing happened, I realized that it was Sodium Sulfate crashing out. I am assuming it was sodium sulfate due to the sulfuric acid + sodium nitrite reaction. I also tested it and found it didn't dissolve in alcohol but did dissolve in water as well as glycerin, which is how sodium sulfate reacts.
I added the filtrate to a little bit of water and then put it in the freezer. When the filtrate got to 2°C, the first crop of NaNTz crashed out. I reduced the filtrate again and put it back in the freezer and got the second batch of NaNTz. It really is amazing how easy it is to produce NaNTz from the 2017 patent batch method. No dangerous intermediaries micro-detonating. My final(acetone purified) yield was 50% of 5-ATz.
супер!
Why was the acidification step after the filtration necessary?
made NaNT using a large scale flow reactor. No need for copper to stabilize the diazonium. Purity was extremely high after insitu work up. Resulted 99.5% NANT in perchloric acid. Made 20kg in one day.
You should make a video of your process.
Did you use the microchip method flow reactor from the patient? Would love to see the setup.
I also avoid the acid copper intermediate. Direct diazotization of the acidified 5-ATZ with NaNO2 @ elevated temp 65°C. Small batch method.
@Chemistry'sCuriosities Cannagorilla I am using the same batch method. I can process 70g of 5-ATz in 30 min. Getting 40g of NaNTz recrystalized from Acetone. I am using Sulfuric Acid.
It is stable relatively, better than tatp.
zonex001 my friend- ANYTHING is better than TATP or HMTD. This stuff is among the cutting edge of primary explosives. You can fire even the most insensitive secondaries with as little as 5-10 mg with most explosives based on this one. NaNTZ is not the best itself but the compounds made from it are excellent initiators.

Nice video! I found this link with the detailed procedure:
