New ETN Synthesis
Many of you maybe have seen this video:
https://www.bitchute.com/video/XrjpCnYs7fVL/
(Ammonium nitrate + Sulfuric acid method of nitration with excellent yield and good price.)
I used this method for etn synthesis, And I have to say that despite my skepticism about the outcome, I came up with some interesting results.
Erythritol:10g
H2so4:100g = 51cc
Nh4no3=40g
Etn:23g
With this method, I obtained about 23 grams of etn (~92%).
To be absolutely sure of the result, I calculated the density and melting point of the product.
melting point :~around 60c
Sample density with weight 6.75g & 4cm3=> 1.68
In my opinion, compared to,2acid method,is cheaper and more efficient. Thank you

Is that 23g of ETN bone dry? My yield is always around 14 or 15 grams when following that exact video posted. Could you give more details about your
procedure?
http://www.sciencemadness.org/talk/viewthread.php?tid=949&am...
Following the link you'll see Hennig Brand gets similar yields as me using the same procedure. His procedure can be found on page 23 of the link I
posted. Id love some insight on how to get better yields.

Yes,23g dry etn
Use the method described in the video.

I believe it may but my AN, I have followed the video and also tried the "#10" trial shown at the beginning of the video and do not get these good
yields. I am going to try a re-crys and see if that helps.

re-crystal will not help you. you must use pure ingredients.

Recrystallizing should purify the AN so it can be more effective, that is kind of the point of a recrystallization, purification.

I am using 93% sulfuric sourced from drain cleaner, the only additives is a pinker dye to show up against tubs. My AN was sourced as cold pack
refills, not sure how pure as it has bits of rock in it. My AN my have moister who knows. If anyone else is able to replicate the results in the video
I would love to hear how you did it.

That's exactly right. I didn't mean ammonium nitrate. we should use pure nh4no3.

I tested 6.75 sample with my no8 blasting cap.
The result was interesting
ETN:6.75g
Density:1.68
Iron plate thickness:6mm

Looks like the sample performed well, melt-cast I am assuming. Do you have a photo of the charge?

I would have expected a little more damage when comparing to this video.
https://www.bitchute.com/video/l3h21B9vSLoU/
These of course are mixed explosives and a larger quantity but still. As I already posted I don't believe my melt cast is performing as it should.

As you can see in the video, the thickness of the iron plate is less than that of the iron I used.

With that much HE, you should have spalling on the back side, if the charge went properly high order. It is hard to see from your pictures if that was
the case...

I was thinking the same, however would that not be depended on the backing of the steal?

Unfortunately, the quality of the photo is not very high. For this reason, the effect of the explosion on the photo is not well recognizable.
In addition, the surface under the iron plate was very dense and hard

Another test with PETN!
15g 70:30 petn/etn (10.5 petn,4.5 etn)
Cap(PETN:700mg- ETN:100mg - SADS:200mg).

What thickness of steel is that, was it an undamaged piece of box section prior to your test?

The second test looks better IMO. I think you should consider the possibility that the detonator is perhaps not quite powerful enough for this charge,
leading to inconsistent performance.

It’s true, maybe my detonator isn’t quite powerful.
However, it should be noted that 6.75 g of etn was used in the first test. The 6mm iron plate was on a hard surface, which affects the impact of the
blast wave on the surface below.

I have tried this method yet again using lab grade 98% acid and lab grade ammonium nitrate. After a re-crys in acetone my final weight was 19 g. Still
4 grams shy of what other can obtain! When mixing your nitration bath do you use any sort of temperature control? I have done around 30 trials and
still can not get higher yields.

Yea I find it weird how people have such varying degrees of success with ETN. Some claimed huge yields using KNO3. I tried for months and the highest
I got was 40% and at that point, the ETN would crystallize out in the bath and almost cause a runaway. Not good. Best yield was around 70% I believe.
Recrystallization seems to steal a lot of my yields though. I used tannerite grade AN and drain cleaner. I'm done wasting my lab grade H2SO4 lol. I
need it for better stuff.
I haven't done anything with energetic chem for ages and actually didn't want to go back but this thread is tempting me haha.
Happy synthesizing and testing fellas!

And I also suspect your first test did not go high order. 10 or 15 grams of my plasticized ETN was far more brisant. Granted it's a bit more but there
was a lot of inerts in there too. I prefer plastics due to ease of molding around the detonator and safety. Damn I sure miss the days where I made
explosives...
The spot I had for my detonations is no more though and I also didn't like the whole super illegal part of transporting explosives as well as having
these things pop up on explosives tests or bomb sniffing dogs. Man...
