safe powerful Nitroglycerin liquid mixtures ?


I read about some NG mixtures which are considerd to be desensitized.

according to this study if NG mixed with 30% acetone or 40% triacetene it will be greatly desensitized and become comparable with TATB !!

but I have some concerns regarding these mixtures :
does anyone tested similar mixtures ?
would mixing NG with raw glycerin give similar results ?

are they still powerful explosives ? would they be stronger than TNT for example ?
should they retain safety even with large diameters?

if such mixtures are safe and powerful why they are not widely used ?

I have never heard of someone testing the sensitivity of NG in acetone. I have only seen acetone used to desensitize NG so that other chemicals (sawdust/cornstarch/AN) can be mixed with it to manufacture dynamite.

It would be more powerful than TNT and my guess would be it would retain the same properties in small and large diameters.
Problems would be that it is a liquid explosive and you can still get migraines from handling it.

Overall, it doesn't meet the standards that are required by explosives nowadays, nitroglycerin has been slowly phased out as an explosive and nearly all of NG that is made would be used in manufacture of propellants.

For mining, we want lower VOD explosives like ammonium nitrate mixtures and not brisant powerful ones that will break rock into too small pieces.
The military wants high energy, high density solid explosives that are easy to handle (PE's/PBX's) and non toxic if possible.
There's not much room left for liquid explosives anymore apart from maybe a few exotic uses, especially ones that are a headache to handle.





The only use for an atomic bomb is to keep somebody else from using one.

If you consider adding acetone for desensitizing, be aware that it could evaporate from the mixture over time which would increase sensitivity. The container doesn't have to be open for this to happen (if it is made of something that acetone can penetrate by diffusion).

Manipulation with liquid nitro compounds and their use is difficult. Nitroglycerin is an outdated energy material. Like detonators from FHg. Just like a steam engine...:cool:...LL

but Triacetin is different, it has boiling point of 290°C. it is also easily prepared .

a mixture with only 25% Triacetin is considered safe for shipping:

Those mixtures are quite weak compared to other explosives of similar sensitivity. 30% acetone in NG lowers the detonation velocity from 7700 m/s to about 5700 m/s and the detonation pressure from 270 to 130 kbar (calculated figures). This is weaker than PLX and a lot worse than TNT.

Very interesting counting, Dornier. 130 kbar is really weak pressure. Is it pity use NG with huge diluting. Shortly, is it nonsense.
