Would reacting iodine with ammonia with iodine yield N2I4

Makes NI3.

N dunt have space for more than 3 bonds (see orbitals).

Adding iodine twice dunt make any difference ;)

I didn't mean that. I meant hydrazine and iodine.

Anyway, what's with the 'dunt?' Something is going on here, and it isn't making me very comfortable.

dunt = doesn't = does not

dunt = idle typing. Nothing more than that.

Still not convinced. Anyway, I'm not known for idle typing, and the ;) at the end makes me smell a rat.

Hey, new member here. What is your suggestion of SAFELY setting off NG? Browsed the forums and the internet for a bit and couldn't come up with a solution. A firecracker as a primary cant set off the NG I made. On the second attempt, i've strapped 3 together in a shotgun shell filled with NG. When the firecracker went off, it pushed the shell (filled with NG) down and with enough force to shatter the container that the rest of the NG is in. I've verified that it is NG because it deflagerates and passes the hammer test.

Silver acetylide is about the 'safest' primary that's easy to synthesize.

A fairly small quantity of pressed TATP will initiate NG with good design but this might not be your idea of safe. Speaking of good design, it's probably the biggest determining factor in safety and is to an extent even more important than the primary being used.

All primaries are dangerous by definition but with proper design most can be handled quite safely.

I'm not going to recommend anything in particular but whatever you do decide to do consider these things.

Keep the cap and main charge apart until you're ready to touch it off.

Obviously use a long enough fuse to get away from your device, none of that light it and run for your life BS.

If you're going to press a sensitive primary use some device to hold the tube in place that will not produce shrapnel rather than hold it in your hand (a bit of styrofoam with a hole in it would suffice), also wear eye/ear protection and use a rod smaller in diameter than the tube.

Ensure no sparks from the fuse can fall into the cap and set it off prematurely. Also make sure no sparks can ignite the fuse lower down and reduce burn time, a few wraps of aluminum foil around the lower part of the fuse is enough to help prevent this. Keep in mind some fuse can be affected by confinement and may burn much faster with the foil around it.

Use a tube that's somewhat thick and sturdy such as a bic pen tube, this will help insulate the primary from heat and physical shock.

Silver acetylide seems promising. Love how it is stable when submerged and how easy it is to make. I've made TATP but pressing that scares me. Thanks for the warnings, im using electronic remote ignition and disks above the NG to stop premature ignition and det. Im thinking about ditching the fuze idea and directly tring to light via e-igniter but I will have to test that.

Nitromethane sensitizer


Quick question. Could Ammonium persulfate act as a sensitizer to nitromethane? Since it is a salt of ammonia which does sensitize Nitromethane id assume it would work. Plus Ammonium Persulfate in itself is a strong oxidizer which may help to act as an oxidizer much like in ANNM compositions.

Given that it is an ammonium salt, and ammonium salts sensitise nitromethane, I doubt that it wouldn't? If you can't work that out, you probably shouldn't be experimenting with it.

@annon 42,

Silver acetylide is great on its own. However, from what I have found, synthesis always synthesises a silver acetylide double salt - a compound of silver nitrate and silver acetylide, which is extremely unstable and very highly explosive.
Tdep discusses it here: https://www.youtube.com/watch?v=y7H0Rwz6Pd8

Personally, I always use hexamethylene triperoxide diamine in my detonators.

Silver acetylide is significantly less shock and friction sensitive than HMTD though, not to mention it needs less 'run up' to reach full velocity so a much smaller quantity can be used.

~100mg of SADS on top of 1g heavily pressed ETN is a good cap in terms of safety, power and reliability, it's a far better cap than just plain pressed HMTD.

I know, but silver acetylide double salt terrifies me... If that went off in my hand, I would embed it in the ceiling.

This is more likely to happen with HMTD!
SADS is safe if you do it right and treat it with respect (no forcing, no hammer shock, no exposure to excessive heat (>150°C) or flame!

What do you think about AP? I've made AP before and when wet it seems relatively stable. Can I press AP into a shell to set off NG? And is AP more stable than HMTD? Ive tried lighting off AP semi contained (film canister) and only got a deflag.

And stop right there. AP - if you mean acetone peroxide - is referred to as the Mother of Satan for a reason. If you are just another random kid who wants to make TATP, fuck off this forum to the chemistry subreddit (or wherever else.) If you know anything about chemistry, you'd know that no one makes TATP because it is too dangerous.

HMTD and TATP are very comparable in all respects with the big difference being at similar crystal size *HMTD is more friction sensitive*.
All organic peroxides are both poor choices but HMTD is just as bad if not even worse than TATP.

There's a difference. He is obviously inexperienced. Although I am definitely not the best, I count myself as good enough to be able to work with HMTD in small quantities. HMTD is more dangerous, but is a specialist chemical that requires experience. The only reason that I collapsed on him so hard is that I can see another Phone disaster - he synthesised TATP 'for fun' out of extremely easy to find chemicals with no prior experience and blew himself up. I am trying to tell him to stop for his own protection.

If by AP you meant ammonium perchlorate, or ammonium picrate, no problem.

Better explain more abreviations to avoid confusions...

Yes, TATP pressed into a tube would work just fine if you decide to go that route.

It's very important to properly synthesize TATP though.

Everything should be kept as cold as possible at all times.

Obviously it needs to be deacidified thoroughly.

Even the acetone should be added dropwise since some heat is generated upon addition to the peroxide.

It should not be gritty in the least, when rubbed between your fingers it should be completely smooth.

Anyone who rubs any organic peroxide between his fingers should be taken out of the gene pool.

Ok looks like neither TCAP or HMTD is a good choice. Silver acetylide it is then. TCAP and all energetic are said to be way more sensitive than they actually are (thats not an excuse to treat it that way though). I've done a lot of lurking here and know how to properly synthesize what I am making.

Coming from the guy who insists HMTD is preferred over SADS?... Funny :D

Gently rubbing a small quantity of TATP between your fingers is a much safer alternative to pressing a much larger quantity of it with an unknown crystal size.
Unless you have an alternative method of determining crystal size short of examining it under a microscope, I'd love to hear it.

You do have a point... From my own personal experience, HMTD>SADS. Tdep's video I linked above: the stuff blows up all over the place randomly. That's only from personal experience.
No, I don't. The best thing is not to use organic peroxides in the first place!!

Would this exist:
Ditetrazole azide (two tetrazole groups joined by an azide group off the carbon atom in the tetrazole ring and an NH group in the other group to form a disubsituted tetrazole?

It is possible by hammer test reached the maximum detonation velocity ?
Or a full transfer of detonation waves ?
