hmmm.... H2O2 with a fuel?
Sounds interesting to me.
Which koncentration of the H2O2 is recuired?
- isn't 100% H2O2 quite explosive?!
And what kind of fuel can I use?
How powerfull is these H2O2 explosives and what about the sensitiveness?

I believe our beloved AP solution (H202 + acetone) is a detonatable mixture. The H202 would have to be high conc but not so high that it ignited on contact with the acetone

PLX is a mixture of 95% nitromethane and 5% ethylenediamine. I know not much about its properties but it should be very volatile. I think is just a waste of NM but if you need a liquid it might be worth it. Ethylenediamine shouldn�t be hard to find.
And some rockets fly on a (detonable) mix of kerosene and high concentration H2O2.

The rocket fuel of kerosene and H2O2 didn't mix before use, they are pumped from seperate
chamber into an open burning chamber to create thrust. H2O2 is like water, doesn't mix with oil.
As long as the reaction can continue, minimum
concentration of H2O2 will depend on burning efficiency of fuel it mixed with. 100% will always be the best, but 100% isn't quite stable. The container used for this explosive
has to be SOOOOO clean as if untouched.
Any impurities (fingerprint, metal filing) will cause danger due to the oxidizer nature of H2O2.
Any water soluble fuel(liquid or solid) can be used, except those can form an organic peroxide (hexamine, acetone, urea, etc).
It's an molecular mixture of oxidizer and fuel so it's very powerful but DV not as fast
as HEs'.
This explosive is weaker than HE but it will only need spark, flame, static discharge (pretty much whatever can ignite gasoline) to ignite and will explode without confinement.
Be careful with high concentration H2O2, if one drip goes into your eye, it's gonna retire early.

Excuse the question from the non-chemistry taking guy (I have only had a intro class) BUT, can you distill the water out of h202 or will it just break the bonds down in the h202? I know that certain liquids will concentrate with distillaton since it will drive the water off. Are the bonds in h202 stable enough to stop this?

Freezing water/ethanol produces mainly ice and a more concentrated ethanol solution, but they have very different freezing points. Water and hydrogen peroxide (I think) will have more similar freezing points, so it will be harder and less efficient at seperating them.
I once saw a site on H2O2 rocket fuels from a semi-amateur point of view, that described how to use vaccuum distilation to get from c. 40% to c. 85%, which should be concentrated enough. I can't remember the name of the site or anything, but it shouldn't be too hard to find.

This isn't a liquid explosive, but it falls in about the same catagory.
There's this explosive called "nitromethane foam" or something, and it consists of nitromethane with propane bubbled through it. It can be detonated by means of det-cord.
I believe someone on the forum posted something about this.

I think the best "physical" way to concentrate H2O2 is to vacuum distill it, like Mr Cool presented.
H2O has molecular weight of 18
H2O2 has molecular weight of 34 (almost twice as heavy)
H2O is more likely to escape into vacuum because of its lightweightness.

He all read a bit what he was asking for: a liquid explosive less sensitive than NG!!!!!
Thus no no no!!!!
Panclatite or Panchlastite.
(N2O4/CS2)
-As sensitive and even more than NG!!!
Organic perchlorates.
-spontaneously explosive over 10C and much more impact sensitive than NG
Other nitro-esters.
-About the same sensitivity as NG!!!!
H2O2 and liquid fuel mixtures.
-Need at least 85% H2O2
LOX
-Maybe but most fuels are frozen solid in liquid oxygen (BP arround -180C)...
SO GUYS STOP PLAYING WHIT NEWBIES LIFES!!!!!

An excellent liquid explosive that is less shock sensitive, more powerful and yet more cap sensitive than NG is nitromethanol (MYROL). It's only downside is it's volatility.

If I remember correctly from when i was into that kind of stuff (What im gonna say right now) The German Me163 Komet (a small rocket propelled airplane of WWII) Used a hypergolic engine that used H2O2 and hydrazine (actually, C-stoff and T-stoff as they called them. One i KNOW is H2O2 and im fairly sure the other is hydrazine. They were in separate fuel tanks, of course, but mixed in the engine). Ive seen one of the engines that used that stuff, and it was about 10 ft long, and looked like a big pipe basically, but obviously quite powerful. If you wanted to blow something up with it, you could probably figure out some way of keeping them separate and mixing on command.

It will work but the hydrazine needs to be anhydrous and is also very toxic and reactive, I wouldn�t go near that stuff!

If you have a a vacuum still, apparently there easy to make, never suceed myself however, then you can distill the H2O2 more concentrated. You may now be thinking, how the %&*!, so i'ii explain, before you apply the vacuum to the H2O2 you mix it with alot, depending on how concentrated you want the H2O2 and how much water is in your H2O2, apply the vacuum and distill of very concentrated hydrogen peroxide. In case anyone comes up with this, put you can of course then heat up the acid and reuse it. Even the poor grades of acid many of us get will do the job, put yield will be poor first run or to, as H2O2 your adding will clean alot of decomposing impurities, although not all, so you would have to test your acid.

I know very little about chemistry,so please bare with me,but could the H202 be concentrated by a few runs through a dessicator with anhydrous cal. chloride (or mag. sulfate)?.Or would the peroxide have a stronger affinity for the water than the drying agent?.

Yes, it would work because H2O2 is less volatile than H2O but don't ever pass its solution through the dry CaCl2 or MgSO4!!!
I hope you will dessicate it in a big closed vessel at ambiant temp (20C-35C) within what there will be another vessel containing the dessicant!Don't forget to add some sulfuric acid in the H2O2 to stabilise it when higher in concentration.
Always remember that H2O2 and metalic ions are not good friends at all; CaCl2 and MgSO4 contains such ions!!!!They can bring your batch to zero contain oxygen in very little time if brought into contact!!!!

Of course it won't be possible to go to the 100%H2O2 since after a while, when more concentrate, H2O2 will begin to volatilise and adsorbs on the dry salts...

Know a couple more explosive types can maybe save your lives one day.
H2O2 based explosives are sprengel explosives
, or "mixed-on-site" explosives.
Anyone thinking about mixing it together and store the explosive in the fridge is a big idiot.

Only in concentrations of 86% and above with use of high-energy initiator will H2O2, itself detonate. For pure Hydrogen peroxide (100%) and for those who are interested, I have made the following calculations:
Molar mass: 34.016
Oxygen balance: +23.52%
Oxygen content: 94%
Density: 1.4425g/ml (25�C)***
Heat of formation: -44.85 kcal/mole***
Heat of explosion: 372 kcal/kg (H2O gas) (when pure H2O2 explodes or detonates according to the reaction):
2 H2O2 --> 2 H2O + O2
(H2O.liq. value: 702 kcal/kg)
Gas volume of detonation: 988L/kg
Detonation velocity: @ 1.40g/cc = 5730m/s
.....................@ 1.44g/cc = 5840m/s
Detonation pressure: @ 1.44g/cc = 131 kbar
*** Not calculated.
My approximations for VOD do not seem out of significance since 90.7% H2O2 aq. solutions have reported VOD's of 5500m/s to 6000m/s.
H2O2 mixed explosives are very powerful but they can lose explosive power and lose peroxide, they can be dangerous in presence of trace metals, dust, dirt, catalysts and spontaneous ignition may occur. Some fuels can react spontaneously and explosively with strong hydrogen peroxide. Concd. H2O2 solutions (ex. 30%) can build peroxides with some reagents without reaction catalysts upon standing (ex, with acetone, ether, etc.). Soluble fuels (acetone, ethanol, glycerol) will detonate on admixture with peroxide of over 30% concentration, the violence increasing with concentration. These solutions are not ideally the safest! Mixed H2O2 explosives are risky.

Nitromethane, a liquid explosive, on its own will not detonate, it requires sensitizers. The most common sensitizer would be the ammonia ion, so a small amount of substances such as ammonium hydroxide, ammonium nitrate, aniline and ethylenediamine are added. There are a few other sensitizers however, I believe someone mentioned propane, yes that works. A mixture of 50% nitromethane and 50% picric acid (picric acid is incredibly soluable in NM) is a powerful, brisant liquid explosive that is sensitive to a #6 cap.

Freezing water/ethanol produces mainly ice and a more concentrated ethanol solution, but they have very different freezing points. Water and hydrogen peroxide (I think) will have more similar freezing points, so it will be harder and less efficient at seperating them.
I once saw a site on H2O2 rocket fuels from a semi-amateur point of view, that described how to use vaccuum distilation to get from c. 40% to c. 85%, which should be concentrated enough. I can't remember the name of the site or anything, but it shouldn't be too hard to find.

This isn't a liquid explosive, but it falls in about the same catagory.
There's this explosive called "nitromethane foam" or something, and it consists of nitromethane with propane bubbled through it. It can be detonated by means of det-cord.
I believe someone on the forum posted something about this.

I think the best "physical" way to concentrate H2O2 is to vacuum distill it, like Mr Cool presented.
H2O has molecular weight of 18
H2O2 has molecular weight of 34 (almost twice as heavy)
H2O is more likely to escape into vacuum because of its lightweightness.

He all read a bit what he was asking for: a liquid explosive less sensitive than NG!!!!!
Thus no no no!!!!
Panclatite or Panchlastite.
(N2O4/CS2)
-As sensitive and even more than NG!!!
Organic perchlorates.
-spontaneously explosive over 10C and much more impact sensitive than NG
Other nitro-esters.
-About the same sensitivity as NG!!!!
H2O2 and liquid fuel mixtures.
-Need at least 85% H2O2
LOX
-Maybe but most fuels are frozen solid in liquid oxygen (BP arround -180C)...
SO GUYS STOP PLAYING WHIT NEWBIES LIFES!!!!!

An excellent liquid explosive that is less shock sensitive, more powerful and yet more cap sensitive than NG is nitromethanol (MYROL). It's only downside is it's volatility.

If I remember correctly from when i was into that kind of stuff (What im gonna say right now) The German Me163 Komet (a small rocket propelled airplane of WWII) Used a hypergolic engine that used H2O2 and hydrazine (actually, C-stoff and T-stoff as they called them. One i KNOW is H2O2 and im fairly sure the other is hydrazine. They were in separate fuel tanks, of course, but mixed in the engine). Ive seen one of the engines that used that stuff, and it was about 10 ft long, and looked like a big pipe basically, but obviously quite powerful. If you wanted to blow something up with it, you could probably figure out some way of keeping them separate and mixing on command.

It will work but the hydrazine needs to be anhydrous and is also very toxic and reactive, I wouldn�t go near that stuff!

"T-Stoff" 80% H2O2 with H3PO4 as stabilizer.
"C-Stoff" Mixture of Methanol, Hydrazine hydrate and Potassiumcuprous cyanide solution.
"Z-Stoff" were the permanganates, ex, calcium permanganate = Z-Stoff C

If you have a a vacuum still, apparently there easy to make, never suceed myself however, then you can distill the H2O2 more concentrated. You may now be thinking, how the %&*!, so i'ii explain, before you apply the vacuum to the H2O2 you mix it with alot, depending on how concentrated you want the H2O2 and how much water is in your H2O2, apply the vacuum and distill of very concentrated hydrogen peroxide. In case anyone comes up with this, put you can of course then heat up the acid and reuse it. Even the poor grades of acid many of us get will do the job, put yield will be poor first run or to, as H2O2 your adding will clean alot of decomposing impurities, although not all, so you would have to test your acid.

I know very little about chemistry,so please bare with me,but could the H202 be concentrated by a few runs through a dessicator with anhydrous cal. chloride (or mag. sulfate)?.Or would the peroxide have a stronger affinity for the water than the drying agent?.

Yes, it would work because H2O2 is less volatile than H2O but don't ever pass its solution through the dry CaCl2 or MgSO4!!!
I hope you will dessicate it in a big closed vessel at ambiant temp (20C-35C) within what there will be another vessel containing the dessicant!Don't forget to add some sulfuric acid in the H2O2 to stabilise it when higher in concentration.
Always remember that H2O2 and metalic ions are not good friends at all; CaCl2 and MgSO4 contains such ions!!!!They can bring your batch to zero contain oxygen in very little time if brought into contact!!!!

Of course it won't be possible to go to the 100%H2O2 since after a while, when more concentrate, H2O2 will begin to volatilise and adsorbs on the dry salts...

Thanks for the quick answer,PHILOU Zrealone!.The dessicator i'm referring to does indeed have two seperate glass trays,one above the other.

Know a couple more explosive types can maybe save your lives one day.
H2O2 based explosives are sprengel explosives
, or "mixed-on-site" explosives.
Anyone thinking about mixing it together and store the explosive in the fridge is a big idiot.

Only in concentrations of 86% and above with use of high-energy initiator will H2O2, itself detonate. For pure Hydrogen peroxide (100%) and for those who are interested, I have made the following calculations:
Molar mass: 34.016
Oxygen balance: +23.52%
Oxygen content: 94%
Density: 1.4425g/ml (25�C)***
Heat of formation: -44.85 kcal/mole***
Heat of explosion: 372 kcal/kg (H2O gas) (when pure H2O2 explodes or detonates according to the reaction):
2 H2O2 --> 2 H2O + O2
(H2O.liq. value: 702 kcal/kg)
Gas volume of detonation: 988L/kg
Detonation velocity: @ 1.40g/cc = 5730m/s
.....................@ 1.44g/cc = 5840m/s
Detonation pressure: @ 1.44g/cc = 131 kbar
*** Not calculated.
My approximations for VOD do not seem out of significance since 90.7% H2O2 aq. solutions have reported VOD's of 5500m/s to 6000m/s.
H2O2 mixed explosives are very powerful but they can lose explosive power and lose peroxide, they can be dangerous in presence of trace metals, dust, dirt, catalysts and spontaneous ignition may occur. Some fuels can react spontaneously and explosively with strong hydrogen peroxide. Concd. H2O2 solutions (ex. 30%) can build peroxides with some reagents without reaction catalysts upon standing (ex, with acetone, ether, etc.). Soluble fuels (acetone, ethanol, glycerol) will detonate on admixture with peroxide of over 30% concentration, the violence increasing with concentration. These solutions are not ideally the safest! Mixed H2O2 explosives are risky.

Nitromethane, a liquid explosive, on its own will not detonate, it requires sensitizers. The most common sensitizer would be the ammonia ion, so a small amount of substances such as ammonium hydroxide, ammonium nitrate, aniline and ethylenediamine are added. There are a few other sensitizers however, I believe someone mentioned propane, yes that works. A mixture of 50% nitromethane and 50% picric acid (picric acid is incredibly soluable in NM) is a powerful, brisant liquid explosive that is sensitive to a #6 cap.
