This is my new TNT
now I will be able to test composition B and pentolit!

I am jealous

I see your 1 lb of TNT

wessonsmith - 29-11-2019 at 11:15

and raise you 2 lbs of 1.9 RE Thermobaric Composition.:)

It's my Thermobaric Comp.

ETN 55.00 (g)
Al(3μm/) 12.00
Mg/Al(44μm/325mesh) 18.00 (50/50 mix)

Soy Lecithin(liquid) 0.300
lmwHTPB Resin 11.69 (lmw=Low Molecular Weight)

Modified MDI Isocyanate Curative 1.84
CAO-5 Antioxidant 0.44

Petn1933 - 29-11-2019 at 20:01

So blow it up as soon as possible!

TGSpecialist1 - 30-11-2019 at 08:54

You should try a 50/50 melt of TNT with Fe2O3 or MnO2, it would first get reduced to Fe/Mn vapor then reoxidized by air, the effect could be interesting.

TGSpecialist1 - 30-11-2019 at 09:09

How many batches it took to make a half kg of ETN?

I can make 600g twice recrystallized in (2) batches.

I make 315mL of Fuming Nitric Acid in 1 hr using 850g of Potassium Nitrate and 510mL 98% Sulfuric Acid.

ETN is made using 180g Erythritol dehydrated with 440mL of 98% Sulfuric acid, then nitrated with 315mL of the Fuming Nitric Acid. The yield is 300g of ETN 67.8% of theoretical.

Petn1933 - 30-11-2019 at 11:36

I think fuming hno3 should be used for more important things:)

It is effortless and relatively inexpensive for me to make fuming nitric acid. It's cheaper for me to make fuming nitric acid than it would be for me to buy 67.2% nitric acid. Plus, purchasing 10L of 67.2% nitric acid would get me to put on a watch list.

What's your procedure for making Nitric Acid, as a matter of interest?

It did? How, and for whom?

EDIT: Oh, for the OP's new boomstick - I see. :)

1000mL round bottom flask in a heating mantle with a distillation setup. The key is to use salted ice (I use Ammonium Nitrate) to keep the distilled Nitric Acid very cold so that the Nitrogen Dioxide stays dissolved in the Nitric Acid. I turn the heating mantle to high until I start to see bubbling, then reduce heat to medium. I let the Potassium Nitrate turn into a gel-like consistency and then crank the temperature to 90% high. This pushes the conversion to Nitric Acid into overdrive. Yes, you are creating some Nitrogen Dioxide due to the higher temp, but since the receiving flask is chilled, it remains dissolved in the Nitric Acid.

When I make ETN, the Fuming Nitric Acid starts at -15C, then I add to the Nitric Acid the dehydrated Erythritol dissolved in Sulfuric Acid in 4 parts. Doing it this way, you will not see any brown Nitrogen Dioxide fumes because, under 15C, the Nitrogen Dixoide converts back into Nitric Acid in the presence of H20.

The advantage of dehydrating the Erythritol in 98% Sulfuric Acid first is that you eliminate the chance of a runaway when you nitrate it since you need to heat the nitration mixture instead of cooling it.

Watchlist is very important! be careful!

Petn1933 - 30-11-2019 at 22:24

if for etn synthesis we use this ratio , the product purity is about 65%
H2so4: 90 ml
Hno3: 60 ml
Erythritol:15
Of course, this is the way for people like me who don't have fast and convenient access to fuming hno3!

This movie is about a tnt factory in Canada in 1943. I think it's worth seeing.

Rocinante - 1-12-2019 at 05:38

Wesson: when will be able to see a video of your composition? Like 50 g above ground test ( 1 m above the ground, paper box 1 m from it).

I'm waiting too!:/

wessonsmith - 1-12-2019 at 10:19

So here is a video with 190g of thermobaric comp in a homade device. 2.1 meter deep water.

Put the headphones on for full effect.

I would need to travel at least 1.5 hour away from where I live to set this stuff off above ground. It is VERY loud and could be heard for a mile in all directions. Underwater is still very loud.

phlogiston - 1-12-2019 at 17:12

EM is not my main interest, so please excuse my naivety, but if I understood correctly that thermobaric explosives use atmospheric oxygen to oxidise the excess fuel in the composition, would detonating them underwater not severely compromise their potential energetic yield?

The aluminium burns in hot water vapor.

Smith: Do you have a spare TBX grenade? Could you place a weighted down empty plastic bottle in the water, like 5 m away from it. Just to see the effect of the device at 5 m, underwater?

Yes I have plenty, but finding a water source 5m deep away from people isn't very likely for me.

Thank you

Wisson: in episode 2, prepping the fuse& squib. if i use military fuse instead of viscos fuse Still need microcrystalline cellulose?

Rocinante - 5-12-2019 at 10:35

No, I mean in the same pond as in the video. The bottle can be near the shore. Just to see the underwater shockwave effects.
It pains me to see such beautiful devices without having propper test videos showing their power.

Yes. The cellulose prevents stray sparks from running down the length of fuse and prematurely igniting your primary. That would be a horrible thing.

I'm military. In the past training a few pounds of tnt was not used. This is one of them

I thought it looked like a standard demo charge.

Microtek - 10-12-2019 at 22:51

Petn1933: I think the technique in the video you posted looks very promising, especially the part where he stretches the rolled up film. This will likely compress the powder filling to a more consistent density, and also lessen the likelyhood of the flame flashing through low density regions (for a fuse). I think it is a very elegant way of exploiting the mixed amorphous and crystalline domains in the plastic film. AFAIK the reason that many types of polymer become stronger when they are stretched is that the stretching aligns the polymer chains, making the plastic more crystalline (and therefore stiffer and stronger) in the stretched part. Then when you continue pulling, the unstretched regions are the weakest part and therefore become stretched next.

Petn1933 - 11-12-2019 at 09:04

Exactly, very useful and cool idea!
