Getting rid of Nitroglycerine!

How can I Getting rid of Nitroglycerine and Nitroglycol from a mixture of ammonium nitrate or urea nitrate.

Note: I do not like to lose ammonium nitrate and urea nitrate.

Thoroughly wash the mix with a solvent in which the AN/UN is insoluble and the NG/EGDN is soluble. Acetone meets the latter requirement, a simple experiment with pure AN/UN will show if it meets the first one.

Do you want to "un-mix" an explosive mixture that you prepared and are unable to detonate because of bad weather/ no suitable place for the detonation?

Yes, I perpared a few kilograms, I'd like to make nitric acid from AN/UN mixture.
Then, how can I separate AN and UN.

I think attempting to chemically dissasemble an explosive mix so you can reuse the parts is one of the dumbest things you can do.

Destroy it in the safest method you can.

Yes I agree why do you want to salvage the AN?. Just det the NG/AN mix and go buy some more AN.

:):):) Weird demand:P:P:P
1)Add half a litter water per 100g then get the AN and UN dissolved
while the PTTN (propantriol trinitrate) and the EGDN (ethylenglycol dinitrate) remains almost undissolved...do a simple decantation and isolate two phases. If agitation to help dissolution is needed; the it must be cautious mild agitation because nitric esters are shock sensitive...
The water layer is the AN/UN and the oily layer is the organic sensitive explosive (PTTN + EGDN). A single tiny drop heating test will show which is which...the organic layer burns like ethanol eventually explodes while the aquous layer will remain liquid then cristallise and burn later.
2)Evaporate at 30-40°C the water and recollect the solid AN/UN (with tiny traces of the organic compounds)

:mad::mad::mad:
Isn't it unsafe to mix UN with nitric esters...what must be kept acid free?

To my feeling and experience UN is quite acidic...more than AN...so I wouldn't be too keen to play with the hydrolytic properties of UN towards a batch of PTTN/EGDN...

Such mixes must then be used on short terms...storage is inadvisable.
