NaClO4


Hi, I have question: Will be it worked ?
4 KMnO4 + 3 NaClO2 + 2 H2O = 4 MnO2 + 3 NaClO4 + 4 KOH
Or it is nonsense? NaClO2 is free as pool chemicals. Usually 25% in H2O. KMnO4 is free. MnO2 is possible decantation, KOH will be possible separe via different solubility. Target is NaClO4 of course. Thanks, ...LL...:cool:

Seems too good to be true...if it was true then KMnO4 would change NaCl directly into NaClO4.
Usually KMnO4 or NaClO2 reveal their oxydoredox potentials in acidic or in basic media...and usually a strongly basic component is not produced (in the products of reactions).

From experience, oxydoredox exercises are just made to use/practice the chem theory of oxydoredox and equilibration thus not always taking in account the validity/reality of such reactions...

Thanks, Philou. I have a same opinion. Much easy and maybe good only in school. Only one a way for truth. Try it.

I was wondering if anybody knows of a Tetryl synthesis that requires 70% nitric rather than the80% specified? Can you just adjust the weight needed of nitric or will the excess water interfere? Or even if tetryl can be made using a nitrate salt in lieu of acid. I have a small amount of dimethyl aniline and don't really want to waste anymore on botched synthesis.

Nice,
I will just add that spg 1.40 HNO3 is 67% so with 69%-70% the exces must be slighly less --> 35-36 fold instead of 40.

Can someone help me understand how to apply plasticizers and binders successfully depending on the energetic compound used?
Examples: PETN (Can the mix below work similarly?)
ETN+EGDN+NC (this will work, right?)
This is a new area for me, so I'm not sure if there is a special ratio or if it is just a sort of mix-until-putty deal. Thanks.

The ETN , EGDN-NC mix is not really a plastic mixture in the sense of the word but basically a blasting gelatin with ETN added. I remember an old user here Ral123 made this and I recall him saying it handles poorly and is volitile due to EGDN and has a limited shelf life. I had also tried this combination but with NG once and found that once the ETN was added it dried it up making a cohesive homogenous mixture impossible to achieve.
Real plastique a however can last a very long time if the energetic material used is sufficiently pure. There is no set rule on amounts of plasticisers/ binders to use but typically 9% for C4 and upto a huge 30% had been reported for low grade knockoff Semtex. This would be barely able to fire properly and was probably on the threshold of usefulness, more like playdoh....

I usually try for 11-12% for high density in a well held together mixture that is still malleable without crumbling but this does require a lot of work and quite some practice to get it right. This also depends on what materials you will be using though.

2-EHN


Has somebody experience with fuel 2-ethylhexyl nitrate? (2-EHN diesel booster) in mix with any oxidizer? As explosive material, of course. Is available on Ebay. Slightly expensive, but has universal using. OB = - 196. Thanks,..:cool:...LL

60:40 tetranitromethane:2-ethylhexyl nitrate will create an extremely powerful and very sensitive liquid binary explosive... TNM + miscible fuel is generally considered bad news.

Owing to the large alcanic counterpart, the density of 2-EHN will be low and so detonic performances aswel...
Better work with denser fuels of the aromatic type...
Hexamethylolbenzene hexanitrate (C6(-CH2ONO2)6)/ TNM (or HNE) would be a much better choice...

Isopropyl nitrate or Ethyl nitrate would be denser and more explosive (better OB)...the density of 2-EHN will be low (0.9-1.0) and its hydrogen content will depress detonic performances...better get an unsaturated system with double bonds or triple bonds (or aromatic) to increase density and energy output per volume.

Purification of nitromethane

Does anyone know how to purify nitromethane from oil and additives? Laws in my country restrict nitromethane above the ratio of 1:3 nitromethane:fuel, and I have 1 litre of 25% NM. Any ideas?

Depends on the fuels...
Evapo-condensation/distillation (<105°C) will take all volatiles (alcools (methyl, ethyl, isopropyl), water, aceton, ... and NM) the remainder will be heavy oils or less volatile compounds.
Then if needed water dilution to take all alcools, aceton away the unsoluble oïl should be NM.

A simple carreful distillation at 95-105°C should get you nearly pure NM.

Dont know if posted before, tryd to search but did not find the awnser..

I mixed kclo3/xylene ones and left it a closed zipper bag and left for 1 and a half days and worked great when i used it.

Made the same agein with same ratio and left for maybe 30min and it dident go off..

Is it possible that it needs to sit for a while and soak for a day to work properly?
And is it like this with an Also? Couse same happend with my an/xylene mix when left for about 30min before trying to detonere it.

It is certain. Surely, by common sense it must be? If it detonates after one day soaking and not after half an hour, it needs to soak.

Scientific technique?

And, just so you know, 66:25:9 NaClO3:DEG:water/xanthan gum is a plastic explosive. Thanks Liptakov. I think that it might also work with ethylene diamide (PLX-100)

By the way, do YOU think that NaClO3 would work better than KClO3, and if so why?

That's fine.
By the way, make sure that all your chemical equations are properly capitalised: naclo3, NaClO3 and NACLO3 mean very different things.

In short, use sodium chlorate instead of potassium chlorate, as sodium chlorate is highly hygroscopic and will absorb the fuel quicker than KClO3. Instead of xylene, use diethylene glycol or ethylene diamide.

Are you sure you're ready for this?

If your fuel is hydrophilic, yes (NaClO3) otherwise it depends but in general no (--> KClO3)!

What is the ethylene diamide (PLX-100) you spoke about?
Do you have a chemical formula for it?

Sorry for the typo: autocorrect is a bitch. I meant ethylenediamine.

PLX-100 is a liquid explosive comprised of 95% nitromethane and 5% ethylenediamine. VoD is around 6300 m/s. I don't have very much experience with it (I don't like liquid explosives.) It looks pretty brisant, although I don't have any specific tests to cite.

My other speculation was a plastic explosive alike to LL's plastics, using ED as fuel.

I recall an explosive patent for mixtures using various mixture of 2-ethylhexyl nitrate, ammonium perchlorate and azodicarbonamide (a blowing agent for plastics, occasionally used as a leavening agent in bread!), occasionally with auxiliary metallic fuels, sometimes with other oxidizers.

Some quite high velocities were claimed, I recall. Discussion was on the old roguesci.org explosives & weapons forum- I have not yet run down the patent number, but here is the meat:


Quote:

What is claimed is:

1. A multi-component explosive composition comprising a mixture of a first fuel comprising 2-ethylhexyl nitrate, a granular solid oxidizer, and an additive capable of lowering the sensitivity of the explosive consisting essentially of azodicarbonamide, said mixture forming a detonable explosive.

2. An explosive composition comprising 2-ethylhexyl nitrate in an amount of 9.65% by weight, aluminum in an amount of 9.65% by weight and ammonium perchlorate in an amount of 80.70% by weight.

3. An explosive composition comprising 2-ethylhexyl nitrate in an amount of about 13.3% by weight, azodicarbonamide in an amount of about 4.8% by weight and ammonium perchlorate in an amount of about 81.9% by weight.

2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

VoD


Well, thanks Bert. However I can not find anywhere nothing measurement of VoD. If is VoD (for example) under 3000 m/s, next development is nonsense. Other word, much low velocity. But nobody nothing know. Huh...:cool:...LL

As you said, no hard numbers for velocity- Just a general claim that they expect it to be high, based on over pressure at a certain distance, compared to a known explosive.

DIY


Well, well...I read this patent minimal 5x. But it is a like reading UFO evidence. Patent is from y. 1996. Thus young. It is a big problem do it measurement VoD? I think, that patent was assigned for two homemade DIY. Even according text, which is as for childrens from basic school. Thanks Bert, ...:cool:...LL

Here in USA, it costs about 3X the price of nitromethane in 5 gallon lots. Plenty of well documented high velocity mixtures with NM...

I have read up on Dautriche method, as well as various schemes using oscilloscopes & different detection methods, high speed photography, etc. to determine VoD. Never tried to perform the work-
