Bamboozled

Welp, the time has come for me to dispose of my HMTD. It's just too dangerous for me to handle, nor do I have a proper way to store it. I need a way to dispose of it chemically, and if push comes to detonation, then I'll just blow it up underground.

Now what I need from you guys is a simple (preferably) way to dispose of it chemically. Now: I know that cc. NaOH (solution) works for TATP, will it work for HMTD?
ANY help is warmly welcomed.

Cheers!

May be best to dissolve in a solvent and safely burn. What quantity are you talking about?

HMTD hydrolyses slowly in cold water so its disposal is not that big a deal . . . ?

In boiling water the decomposition is rapid!

'Course, if you're in a real big hurry?

It does??
I had no idea. I know that it is insoluble so I didn't think that it would work that way.

Problem is, I don't have a lot of this stuff... THF... Helium gas... Copper Chloride... ETC and I am pressed for money as I am getting a job this summer. Plus, I remember someone telling me about dissolving it in Toluene and burning the mixture, which I think I'll try. I just asked this question because I believed the procedure to be different. Thanks anyways.

HMTD is sparingly soluble in water ─ I know of no solvent that will readily dissolve HMTD . . . ?

"sparingly" doesn't give me that good of an idea. Do you have a g/ml or something?

hissingnoise - 1-4-2016 at 11:22

I don't actually, but it's googleable, I'm sure . . .

If you've less than a kg, just deflagrate it in small batches!

That's the problem! I've had some detonate when I was sure it'd deflagrate!

dig a shallow pit, dump it in, set an electric match, then fire from a distance

What is the problem with flushing it down the drain? It does not contain heavy metals so it doesn't form a problem for the environment. If it doesn't explode in your sink it won't do it in the sewer. HMTD is degraded in aqueous environments.

Clean HMTD shouldn't detonate in small quantities when it's initiated by flame!

But contact with strongly heated metal may cause detonation . . . ?

How much do you have?

Thought this might be of interest. Taken from the abstract of the paper, "Determination of peroxide-based explosives with copper(II)–neocuproine assay combined with a molecular spectroscopic sensor":

"The two members of peroxide-based explosives, triacetone triperoxide (TATP) and hexamethylene triperoxide diamine (HMTD), can be manufactured from readily accessible reagents, and are difficult to detect by conventional analytical methods. TATP and HMTD were securely synthesized, taken up with acetone, hydrolyzed with 4 M HCl to hydrogen peroxide, the acidic solution containing H2O2 was neutralized,.........."

Personally, I would just use an electric match for ignition in a safe location. If it was spread out in a thin enough trail it would just deflagrate or at least would be a much less intense/less powerful event than if it was ignited in one big pile. When it's gone it's gone and there is no doubt or need for further worry. The idea of dissolving it in acetone, if a suitable solvent, and burning seems like a good one.

I ended up burying it a 2 feet under dense soil in a compostable container, and let time do its work. It's almost gone now.

I stored a little HDMT long time ago and even pure it decomposes slowly over time, so nature will do its job.
