Sciencemadness Discussion Board - 6km/sec VOD From Cast NaCLO4 Composition

6km/sec VOD From Cast NaCLO4 Composition

jpsmith123 - 26-6-2005 at 01:00

Hello,

I found an interesting group of 3 related U.S. patents (assignee: Dyno Nobel Inc.), regarding a castable, cap-sensitive NaCLO4 composition.

I thought I'd share it here in casy anyone else may be interested.

Spefically, what I though was interesting is the high detonation velocity of approximately 6km/sec claimed for this composition; vis-a-vis the cheddites, for example, which are apparently only about half as great.

According to the patents, the composition (in various similar embodiments) has a density of around 1.5 to 1.8 gm/cc.

The higher density, higher perchlorate percentage mixtures seem to be capable of punching a hole in a 3/4 inch steel witness plate.

According to the patent, the main use is intended to be as "a booster or primer and as a seismic explosive in both normal and small sizes."

The patent numbers are 5665935, 5670741, and 5880399. (In case anyone wants to look at these, I have them in pdf format but they are about 500 kbytes each. Is that too big to upload here?)

The preferred embodiment uses sodium perchlorate as the oxidizer and diethylene glycol as the fuel component; also included is water (a few percent), a thickener of guar or xanthan gum, and some other optional ingredients.

I wonder if other chlorates or perchlorates would give even better performance?

I wonder if glycerine, for example, would work as well as diethylene glycol as the fuel component?

Regards,
Joe

Maniak - 26-6-2005 at 03:12

I was interested in this kind of explosives a few years ago - I found the third patent and tried similar mixture:

66%NaClO4 + 9%H2O + 25%ethylenglycol

Sodium perchlorate monohydrate (contains 12,8mol.% water) and no water were used, but still there were particles of solid perchlorate in the fluid - EG is not so good as DEG. Anyway, I'm sure it should be called "brizant explosive", because it's incomparable to some cheddites or the like...
Glycerine might be used, but I think it will dissolve perchlorate much less than EG or even DEG...

Other perchlorates like LiClO4 or Mg(ClO4)2 should be interesting and worth trying because of higher oxygen percentage...

jpsmith123 - 26-6-2005 at 04:17

I wonder how critical the solubility of the oxidizer in the fuel is, in this composition?

According to the 5,670,741 patent: "[T]he preferred fuel is a liquid, water soluble, oxygenated organic material of low volatility. Examples of the preferred fuel include polyhydric alcohols such as glycerol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, and mixtures thereof."

Yet it seems the inventors used only DEG, and in patent 5,880,399, only DEG is mentioned; so maybe this is the best fuel.

In any case, I'm wondering, what did you use for a thickening agent and did you use a crosslinking agent?

And also, what was your composition like after it cured?

Sprengel Explosives

MadHatter - 26-6-2005 at 05:48

Sounds similar to what this thread is describing. One mixture, called rackarock, is made with
potassium chlorate and mononitrobenzene. It was used in New York City to blast out the
Hell Gate Channel on the East River. Right now, I can't find any VODs on this mixture.

Maniak - 26-6-2005 at 09:36

I used no gelants or crosslinkers - my explosive was just liquid and was poured into a plastic cup...but I think some gums (guar, arabic) or polyacrylamide may be used to prepare semiplastic or gel explosive. Another way - you can use it as densifying agent for DAP or the like...

If the oxidizer isn't dissolved, the mixture is not completely homogenous => small amount of undissolved perchlorate is not critical

"rackarock" mixture is very different - it has liquid and solid phase - MNB can't dissolve any anorganic oxidiser - Vdet is probably much lower, maybe about 3000-4000ms-1 in high diameter charges

Rosco Bodine - 26-6-2005 at 10:53

Mixtures of urea perchlorate , hexamine diperchlorate , and ammonium perchlorate in some combination of binary
or perhaps tertiary mixtures could also result in some interesting compositions .

BromicAcid - 26-6-2005 at 19:41

Note that if it is diethylene glycol that is a stumbling block then may I bring to your attention that diethylene glycol is fairly avalible over the counter (98+% in some instances) in those little heating containers for keeping food hot at banquets. Also note that some brake fluids contain appreciable diethylene glycol though I don't know how stable they would be to sodium perchlorate as mixing some of them with 'pool chlorinators' as a few news programs in my area showed a while ago can lead to ignition/explosion of the mixture.

12AX7 - 26-6-2005 at 21:45

Yeah, but pool chlorinators produce chlorine, a much lower oxidation state than perchlorate. Seems to me hypochlorites oxidize damned near anything, whereas chlorates and especially perchlorates are relatively stable. ClO4- withstands concentrated acids!

Ethylene glycol is also antifreeze, humm, I am suddenly disturbed by the mining-scale explosion a gallon of this material could produce.

Tim

jpsmith123 - 27-6-2005 at 00:07

I think I may get around to trying it one of these days using some glycerine and some DEG from "Blaze Canned Fuel", which I assume wouldn't have any unwanted additives like antifreeze probably would.

I think I will try both sodium perchlorate and ammonium perchlorate (as Rosco suggested).

Also, I think I will try using guar gum as a gelling agent with boric acid (or borax) as a cross linking agent (see patent #6838449).

I'm very curious to see what this stuff looks like after it cures.

Maniak - 27-6-2005 at 04:03

Be sure that mixtures with organic perchlorates are much more sensitive and dangerous and they are more unstable because of hydrolyze

But one think which works well - mixture of aq. solution of urea perchlorate (freshly prepared by mixing 70%perchloric acid with urea) with a stechiometric amount of nitromethane, for example:

85%aq. UP + 15%NM

It is oily liquid (dens. 1,4g/cm3), sensitive to cup no.8 with Vdet = 6000-7000m/s, according to US pat. no. 4,047,987

Rosco Bodine - 27-6-2005 at 07:17

Purely theoretical .......

It would seem logical that an oxygen balanced mixture of urea nitrate and ammonium perchlorate would be a very powerful composition . There would likely
be some reaction between the mixed dry or slightly moistened and warmed materials , which would form urea perchlorate and ammonium nitrate by
double decomposition to some extent , resulting in an oxygen balanced quaternary mixture containing :

urea perchlorate
ammonium perchlorate
urea nitrate
ammonium nitrate

Such a mixture could have eutectic properties , even being liquid at mild
temperatures . It could perhaps have interest as a monopropellant as well as
an explosive .

EDIT : After checking the oxygen balance , it doesn't appear that this is workable . The OB mixture would be about 4.2 grams of urea nitrate with 1 gram of ammonium perchlorate . Such a composition would probably not show much improvement over regular urea nitrate . Better would be an OB mixture of urea perchlorate formed separately and then mixed with urea nitrate .

Methylamine Perchlorate is more interesting . See the attachment on the next post .

methylamine perchlorate

Rosco Bodine - 27-6-2005 at 13:25

Methylamine perchlorate is described as having good stability and power , and only slightly hygroscopic .

jpsmith123 - 2-7-2005 at 02:36

Thanks for that interesting patent regarding methylamine perchlorate.

BTW, it seems the commercial sodium perchlorate explosive is called "Dynoseis".

According to the MSDS, the proportions are as follows:

Sodium Perchlorate (CAS 7601-89-0) 66 to 72%
Diethylene Glycol (CAS 111-46-6) 22 to 27%

I couldn't find any published performance specifications (at least in any Dyno Nobel literature) , but I did find some data from another company that supposedly tested it.
Density: 1.78 c/cc
Det. Velocity: 22,000 ft/sec
Det. Pressure: 200 Kbar
Gas Volume: 23.2 moles/kg

Rosco Bodine - 2-7-2005 at 08:13

There is a reaction for mixtures of formaldehyde and ammonium nitrate ,
along with a small proportion of urea ,
which results in formation of methylamine nitrate , along with lesser amounts of di and tri methylamine nitrates .

It seems likely that a similar reaction may occur with ammonium perchlorate substituted for ammonium nitrate , with the result being a mixture of the analogous methylamine perchlorate derivatives .

Certainly the in situ formation of such a mixture from more economical precursors would be more desirable than having to work with free perchloric acid and free amine .

The relevant patents for the reaction are
EP0037862
GB1548827

Likely the mixtures have the same proberties

Ammonium chlorate is avoided like the plague because it spontaneously (dangerously) decomposes.

Fleaker - 28-7-2005 at 09:24

A mixture of ammonium perchlorate and aluminum powder is used in the booster rockets for the space shuttle.

Ref: Kotz, John C. and Treichel, Paul M. Chemistry & Chemical Reactivity. 5th edition. Pg 915. 2003.

jpsmith123 - 12-8-2005 at 08:55

After looking into it some more, I think the key to the performance of this stuff is the fact that the oxidizer *dissolves*, to a certain extent in the fuel.

The increased detonation velocity apparently results from the "molecular adjacency" between oxidizer and fuel molecules you get merely because of the fact that it's in solution. Apparently, in this situation, it's almost like having a molecular explosive.

Apparently it doesn't matter that not all of the oxidizer dissolves (the gelling prevents the excess from settling), if you get enough to dissolve, it supports high velocity detonation.

12AX7 - 12-8-2005 at 11:16

Sounds like it wouldn't hurt to stir it in hot, then crash cool it. Or better still, KClO3/4 grain refiner anyone?

(Grain refiner is essentially seed crystals that aren't very soluble in solution but the primary solute precipitates grows on easily. Such things as titanium boride (TiB2) and zirconium are used as grain refiners for aluminum and copper alloys.)

simply RED - 18-8-2005 at 02:14

Maniak, could you describe exactly what explosive did you try?
What was the diameter and what initiator did you used.
Was it more powerful than rack/a/rock.

I have tried stechiometric ammonium perchlorate and diesel fuel. 5 grams RDX was not sufficent detonator.

Maniak - 19-8-2005 at 04:53

Mixtures of aqueous solutions of perchlorates with fuels are much different from rackarock - components are much better homogenised (liquid or cast) and there is contact on the molecular level => these mixtures are much more brizant and have much higher VoD. These liquid explosives are just slightly less powerfull than some hellhofites and are incomparable to AN-fuel type expl.

I usualy pack this kind of explosives into some film can or similar container with diameter 25-30mm and fire it with standard detonator (0,7g pressed PETN + 0,2g LA in thinwalled Al cup). Of course, this package is inpractical, it's just for testing.

Your output is quite strange - 5g RDX is really enough to detonate your mixture. Try to use better fuel or just perchlorate which is partially soluble in the fuel.

[Edited on 19-8-2005 by Maniak]

simply RED - 20-8-2005 at 04:25

I will try NH4ClO4 + 1,3-propandiol in the beginning of October.

Yes, 5 grams RDX was not sufficent to initiate complete detonation (NH4ClO4 - diesel). The diameter was 3cm, plastic pill box. The whole box was shattered, the brick near the device was shattered too, but tiny particled of the mix were observed glued to the brick particles.
The reason of the low sensitivity was that the NH4ClO4 particles become wet with diesel, and the perchlorate is insoluble in diesel.
Ammonium perchlorate with 10% hexamine (dry mix) detonates readily from 5 grams RDX or 7 grams HMTD (never tried less powerful det). The mixture has 150% the phugass power of TNT and 90% brizance (brizance depending on how well mixed). Diameter 5 cm. One drawback is the mild hygroscopic hexamine...

Request for software relating to Detonics

I am sorry to wander off topic here, but I could not resist asking:

Dose anyone have access to software relating to "Detonics". Software to be used to predict detonation velocity, critical diameter, output energy, effective energy, DDT ect. The reason I quoted Jpsmith123, is because he may have access to Dyno Nobel software:

* 2d Bench - Blast design software for performing timing simulations, load and energy factors, costs, and blasting records.

* 2d View - For viewing designs developed in 2d Bench in 3 dimensions.

* JK Energy Distribution - For viewing energy contours and distribution for design developed in 2d Bench.

* Pro Blast - Practical blast design and cost optimiser that compares two designs using important criteria such as energy factors, powder factors, simulated fragmentation, drill requirements, drilling, explosive and loading costs.

* Pro Bench - Software custom designed for the Mine that adapts the Pro Blast Program in order to evaluate four designs with multiple production blast rows that are each loaded with separate loading schemes. Also has a graphic display in order to compare visually design with decks and angled holes.

* Pro Dig - Excavator productivity program that evaluates blast performance on cycle times to load haul trucks to compare varying blast designs and loading conditions.

And now my two cents to stay on topic:

Simply RED, when you mix Diesel oil with a small amounts of Ammonium perchlorate, it is important to let natural caking do it's work. By just premixing the two, you will introduce erratic density spots. Erratic density can even let an overcritical diameter charge die out. Because you are using such small ammounts, a natural caking process may be beneficial. The detonator has to be put into the Ammonium perchlorate first, and only then the Diesel oil must be added. After this mix has performd a natural caking process, and left undisturbed, it may be detonated. The Ammonium perchlorate must not be packed to tightly though. Using Ammonium perchlorate in Slurry explosives, has less drawbacks. Aluminium powder and /or Nitro methane are good sensitisers and fuels.

Diesel fuel - NH4CLO4 is awful mix...
I may try also adding Al to soluble fuel- perchlorate.

tumadre - 3-1-2006 at 09:07

if you are looking for a solid fuel rocket try polyurethene and ammonium perchlorate this was used in U.S. in bosters, icbms, and other bosters
another liquid fuel mix- a bomb if mixed together
is dimethylhydrazine and nitrogentetroxide
a liquid fuel rocket used for American Cold war material.

NaClO4

Explosives on NaClO4 based, you can see here. His VoD is from 5200 - 7000m/s. Very cheap, easy and very brisant.

Is Sodium perchlorate commonly available as a technical grade chemical in your country?

In my experience, only the Potassium and ammonium salts are cheap and easily sourced in the USA. If Sodium perchlorate can be found at all, it's a higher priced reagent grade.

NaClO4

Laboratory of Liptakov - 13-3-2016 at 10:04

It is usually necessary to prepare NaClO4 in laboratory. Commercial availability worldwide miserable, difficult. Preparation is in a few steps. NaCl (table salt) or bleach. Prepare NaClO3 from the bleach is on you tube about 10x. Next step is conversion NaClO3 on NaClO4. Hot melt method (on YT) , or this method on youtube: https://www.youtube.com/watch?v=8ZnYqmbiukI
Small amount a few % NaClO3 (in NaClO4) is for this type explosive not important. Thus, high explosive from table salt. Get or making HNO3 and H2SO4 is usually difficulty, than produce-prepare NaClO4. Conditions are a quality electrodes, of course. For ClO4....... LL..... :cool:

visualplayer - 10-6-2016 at 23:02

We have made some experiments on this explosive and archieve to reach 6500 VOD, however I'm not comfortable with aluminium powder and water mix. It seems quite safe, but I dont feel safe with that.

Laboratory of Liptakov - 11-6-2016 at 08:46

It are very good results. I recommend decrease content of water for better VoD. Content of aluminium is only for quickly using during 24 hrs. Without aluminium is this composition high stabile. Feel of discomfort with explosives? It is usually. It are explosives. It is for hard guys. ...LL ... :cool:

Very important info from Philou. 100 grams monohydrate is only 85,4 grams of dry NaClO4. But this salt is very hygroscopic. Therefore is usually better heated monohydrate over 140 C and preparation total absolutly dry salt. Easy shortly process on inert surface.

Yes, about 25 times what I would consider reasonable for this as a technical grade chemical. The problem being, most of the production of this goes straight to industrial uses, often in the same plant it was made in. So no cheap, tech grade in small ammounts on offer at resellers as with Potassium or ammonium perchlorates.

110 USD is very expensive. Because titan anode 5 x 7,5 cm , coated platinum is price on e-bay 75 USD. Or less, at details looking for. Even 60 USD for 2 piece. I estimate, that 98% purity NaClO4, amount 1 Kg is possible prepared
with one this anode. Maybe even more, before partially damage platinum coated the surface. How much NaClO4 is possible prepare, it is question for experienced galvanic experts... :cool:

yobbo II - 31-8-2016 at 15:39

Since Sodium Perchlorate has a number of hydrates this will need to be noted if yields are being weighed and calculated. Which hydrate forms depends on the solution concentration and temperature as your product crystallizes. The usually hydrate that forms (between zero and 50°C) is the mono-hydrate. This mono-hydrate must be heated to 60°C to obtain NaCl04:0.8H2O. It must then be heated above 150°C to obtain anhydrous Sodium Perchlorate. Melting takes place at 472°C and decomposition starts at 490°C and ends at 520°C. (Reactivity of Solids 3 (1987) 75-84)

Microtek - 2-9-2016 at 04:03

NaClO4 production via PbO2 coated titanium anodes is actually surprisingly easy, it just takes a long time. As my first ever foray into electrochemistry (which I don't like) I made 200 g of NaClO4 of reasonably high purity using such an anode along with a workshop charger. I electrolysed a solution of NaCl for about 5 days only regulating temp and pH occasionally.
At the end, the small amount of NaClO3 was destroyed by addition of HCl of the highest concentration possible. Since NaCl is insoluble in highly concentrated HCl, you can then decant the perchloric acid.

DrManhattan - 29-10-2016 at 19:36

I recently made a slurry composition containing by weight: 70% Sodium Chlorate
9% H2O
20% 200 mesh aluminium powder
1% guar gum

Charge was 1kg Detonated with a no.8 blasting cap with 10g ETN booster.
Performance was impressive considering the ease of manufacture and availability of chemicals. Id compare it to anfo in power.

Metacelsus - 29-10-2016 at 19:53

Storage stability might be an issue with that composition, so you should store the components unmixed.

jpsmith123 - 29-10-2016 at 20:24

IIRC there is a patent from the 60s (Melvin Cook et al.) regarding sodium chlorate based blasting agents using various fuels such as ethylene glycol, methanol, ethanol and isopropanol.
Unfortunately the patent didn't go into much detail regarding the performance.

DrManhattan - 29-10-2016 at 21:22

Would storage stability problems arise from the fact that the composition contains aluminium and water? Or am i overlooking something. Id like to find a way to make it storable.
I came across a page which detailed a few compositions of Sodium Perchlorate mixtures that might be interesting given their stated VOD of 5800-7010 m/s.

Composition #1
67% sodium perchlorate, 33% matrix.

"The detonation velocity i listed must have been for all the explosive compositions. So the velocity of these compositions ranges from 5800-7010 m/s according to the patent. Not just potassium perchlorate and sodium perchlorate can be used, but most inorganic chlorate or perchlorate salts. Some are more sensitive than others though. 1 lb charges of composition 1 and 2 shattered a 3/4" steel plate and the rest of the compositions blasted holes in the plate."

Laboratory of Liptakov - 2-11-2016 at 13:50

I seems that would Alfred Nobel pretty looking on it..
This composition are same power as dynamite 60%. However without dangerous nitroglycerin. Maybe is possible say, that only hygroscopicity is problem for this mixtures. But it is only one disadvantage. All others properties are better. If you making from this composition dynamite shape and wrapped in aluminium foil is problem almost nothing. And if is the air around pretty dry, under 50%, is it all better than the dynamite. Produce NaClO4 should be easily than produce HNO3 + H2SO4 + nitration + neutralisation process.
PS: Mixtures with Al, this type, are stabbile only 24 hrs. Arises Hydrogen.

Excellent video. Thanks for the link, it was a shame when explosiopedia's channel was removed from youtube but its good to see that he's active on vimeo. As for these mixtures containing Aluminium only being stable for 24 hrs due to the production of hydrogen, couldn't you add boric acid to reduce it? I believe many explosives use boric acid for exactly this reason.

One could also:
1°)coat the Al dust with HE NC lacker (collodion) and dry...to avoid direct contact of reactive Al with water...the NC would contribute to the explosive effect.
2°)use perchlorates that are more soluble into organic solvents to avoid water presence.
3°)use solvents or solvaters that dissolves better oxo-salts into organic solvents (quaternary ammonium, crown ethers, cryptants, ...)
4°)Find a composition with concentrated HNO3 that is storage compatible/safe with fuels...
Al is passivated into concentrated HNO3...but unknown is what happens when NaClO4 or other perchlorates are present aswel?

The international situation is very serious. For this reason videos containing energetic materials, and their preparation was be deleted.

@L-Liptakov,
Today I just had the time to watch your two videos on vimeo about Kidonite, a few minutes later they were deleted :mad:

...only remains your fuel C and minium videos (found by searching via Alfred Liptakov).

The Vimeo Sprengel was stil in action...but for how long?

I am curious, do you remember if the perchlorate completely dissolved? or were there grains of NaClO4 in the composition after mixing? Also, do you know how fine the aluminum powder was? Thank you.

Of course, was tested yesterday. With a new NaClO4 from acetone separation process. Free available patent: https://patents.google.com/patent/US5665935
