Hexamine dinitrate
I have a lot of 25% nitric acid, and I used it to synthesize HDN with Hexamine. I waited for it to cool down, but why didn't it form a precipitate?

And how is purpose your sythesis?
( Hexamethylenetetramine dinitrate ( hexamine dinitrate) itself is of no importance as an explosive. )
You need 50 - 70% Nitric Acid. Not 25%. And temperature of reaction under - 15 Celsius...........

I've successfully made HDN several times following the instruction of this video:
https://www.bitchute.com/video/HshNLFRha9Jl/
I've had the HDN sitting in a box for many months now and I am itching for a chance to turn it all into RDX. But it has been a while.

Thank you. I am preparing to use it to make RDX.

Just use Hexamine for RDX.
Its not worth making HDN.

Is using HDN less exothermic than straight hexamine?

I would imagine so.
More importantly you need less acid if you go via HDN. The last nitro group is hard to get on. If you go direct from hexamine, you reach the point of
attaching the last nitro group with a heap of water, so you need excess acid.

That does make sense. But in the synthesis I did yesterday, the HDN nitration was still VERY exothermic. So much so that I thought I would need ot put
my acid back in the freezer to chill it back down to 0C (it was at 18C, and the salt-water ice block I froze it in was starting to melt heavily and
not cooling it down sufficiently).
But I decided for one final addition before doing that, and that's when the runaway happened. It initially just went to 22C, but then it was slowly
but steadily climbing up, I thought it would stablize, but once it hit 29C I decided to cut my losses and play it safe and I dumped the contents of
the beaker in 6 liters of cold water.
This is one thing I want to ask. Is it acceptable that, after adding some of the material, that (after making sure the reaction has stabilized), is it
acceptable to return the acid beaker to the freezer/fridge to allow it to cool for a while before restarting the addition later? I did sorta do that
with my Keto-RDX synth, but it still resulted in a runaway at the very end.
I was informed that keeping the acid too cold could result in temperature spikes (such as what clearly was going on with my RDX synth) but in many
nitrations I did they were kinda rare. I felt like I might have had a PETN runaway when I was doing the heating step, but it was only after allowing
it to be at room temperature for a while and after the addition of all the PE. Also it might not have been a runaway, but I did see some small red
fumes and I decided to play it safe and dumped it on cold water as well.
The temperature was at 15 and 18C for a while. So I don't think it was because it was at low temperature when starting. I do plan on doing a few more
RDX synths with my HDN supply and I don't want any more near 'life after detonation' events.
