Now I know its an extremely easy synth, but I dont have a thermometer and I did a shitty job.

So instead of using 15 ml 30% h2o2, I used 200 ml 3%. I mixed about 25 ml acetone. I put this in an ice bath but didnt wait for it to initially cool. Then I slowly (Over the course of about an hour) added 25-30 ml muriatic acid. During the wait between drops of acid I put it in the freezer a couple of times. Then I left it outside for about 20 hours.

Anyways it was below 10 degrees celcius for atleast 10 hours.

And all i was left with was probably less than a gram of the stuff suspended in the liquid.

Anyways was it not cold enough?

To concentrate the peroxide do I just boil it?

Does the liquid contain anything dissloved, or is it non soluble?

um toss your 3% h2o2 and don't even bother trying to make more conc.

just goto a health food store or a hydroponic store and get 30% h2o2

thats whats causing your low yeild

I dont have a thermometer

Get one,

And 3%.. Generally a higher % means a higher yield.

An hour = too long.

Other than that get some 40% (at a hair products store) and measure everything out carefully, do all the calculations and use exactly what you need.

hair places do not use 40% they use 40 volume

I didn't do any calculations... but make sure you use excess peroxide... if you use excess acetone some of the acetone will dissolve the acetone peroxide into the solution and you will lose some as you wont be able to filter it...

Back in the day... when I was stupid enough to make AP... I used very little acid and let it run for a very long time... generally multiple days... stirring every few hours and monitoring the crystal size... just keeping it all in a cold place... then I'd go ahead and filter and wash the crystals when I felt that I wouldn't get much more out of the solution.

Simmering H2O2 can work, but you have to be sure that the container your simmering in is exceptionally clean and wont react with the H2O2... IE... brand new pyrex beaker... scratch free... washed with distilled water... Its best to just buy some concentrated stuff...

All in all though... AP is just too dangerous. Flash is alot safer... and thats saying alot. You don't get second chances often with this kind of chemistry.

Yeah, 3% will get you shit for a yield, probably all there's to it for explaining your lack of success.

AP isn't THAT dangerous, if treated with the required respect you're just fine. Of course, that also means you shouldn't be making more than a gram, so your lack of yield isn't the bigger issue here.

... And you shouldn't break up clumps with playing cards.

... Or light very small piles of it when theres a possibility that some of it has gotten into a small hole... which will provide confinement... and possibly propel a chunk of copper into your hand.

... Or mess with alot in your garage.

... Or use hard plugs that can hit you with surprising force.

It IS that dangerous. Most everyone here has got fucked in some way by it.

not me....

safety first

Who had accidents while doing that?

So, I am currently boiling down the 3% h2o2 with hopes to get it around 25% or 30% concentration. I know someone who said this works fine.

But I had it at a rolling boil for a while and it smelt quite strongly of some chemical smell (kind of like a chlorine smell.)

Anyways, I read that the boiling point of h2o2 is about 150 degrees C. I took it off of the burner, and even though its no where near boiling, the small amount of vapour coming off still smells like that chemical smell.

Is this the peroxide evaporating? The only ingredients on the bottle are hydrogen peroxide and purified water.

Help please.

First of all, I suggest you give up making AP, for your own sake. You clearly lack the precision and knowledge needed to produce this safely, so don't even bother. I'm not saying I'm an expert on the subject, but atleast I would know what precautions to take and such. Then again, I'm not making AP.

Secondly, boiling H2O2 is not really smart. Vapours can form under the boiling point. And these vapours can explode in the proper concentration and cause irritation/corrosion to skin/eyes/clothing. Just buy the more concentrated stuff, it isn't that expensive and you'll get away with it. Before you continue, read these chemical safety cards on all ingredients and products: http://www.ilo.org/public/english/protection/safework/cis/products/icsc/dtasht/_icsc01/icsc0164.htm

Also, you should know better than to smell vapours of which you do not know the properties.

I was gonna agree with you until you started on about how dangerous peroxide is. It's not. Especially 3% - you can buy it in the store. And spash it in cuts. It's even recommended for this.

Be paranoid about it (no metals, no shock, a gram or two tops, long fuses) and you'll be ok. Kept lax with it.... well, you get what's coming.



Warwead: F*CK! Thanks. That explains why my hmtd synth failed 80% of the time.

I'm never gonna live it down. :D

I boiled down my H2O2 to about 25-30% and got a shit load yield, way to much for any logical usage. I could have got away with about a 1/4 synth. Just dont make AP, its like CO2 bombs, dont make it because its easy and fast, and it sounds cool. Some of the best results come from hard work, go find a better explosive.

I'm never gonna live it down. :D

You do stupid things and then post them on the internet, of course you're not gonna live it down. :P

My problem with AP was I was too impatient and didn't let the acetone & peroxide cool. Make sure its cold enough? Its pretty simple and most look over it. 3% H2O2 will get an okay yield if done correctly.

20 volume = 3%
30 volume = 6%
40 volume = 9%

ect :P


as for the topic that certain people are more competant then others to produce a organic peroxide

you guys are foolish .. there is NO safe way to produce a peroxide like AP

sure you can reduce the risks by say cooking it colder or by breaking clumps while still reaction ect.....

in a reality everyone who produces a organic peroixe accepts risks of such a dangerous compund ...

and sure some people are more compitent then others when handling and storeing AP but again regardless it is AP


I personally have never controlled temprature i have ALWAYS used 30% peroxide or higher i have always used a beaker i always covered the beaker in saran wrap and then used a ruber band and i have always just mixed all 3 things (acetone peroxide and HCl) and incased it in snow :) then i come back in about 8 min or so take it out of the snow .. mix in some water .... put it in my vacum distilation setup .... run about 3 more washes of cold water through it .. then i dump the ap in a bi card solution ... filter once more dump then filter then i rinse once more in luke warm water the remove any excess bicarb

then i rinse once in iso and spread out on on a surface and it's dry usally in about 4 min

my overal synth time of about 80 grams is about 15-18 min

and my beaker is usally a fairly solid cake of AP

there are really only 2 factors that make AP unsafe and thats it there is HEAT of the reaction and nutralization of the reaction

then thats all that really left is user error ....

storage, handling and transportation



and ALL off it comes down to chance really

you heard that i literally COOK my AP like i mean i cover it to prevent Acetone evaporating and no amount snow would really chill that hot of a reaction ...

i stored my AP usally in a HDPE container under ISO and break up and clumps under that iso with usally a popcycle stick

Anyways, I Added the boiled down h2o2 (probably about 20 or 25%) to the acetone, in a rough ratio of 3:2 h2o2 acetone. I cooled it nicely in the freezer, put it in an icebath and added about the muriatic. About 1:4 volume to the existing concoction. I added the acid over a fairly long while, stirring well. Threw it in the freezer over night, and i was quite amazed with the yeild. I basified it and made some salutes with many more to come. :cool:
Im happy to be back into explosives.

ok i lied

acetone peroxide is like the cough syrup and benedryl of explosives I think.
There are just SO many better alternatives.

Asilentbob, Death_Snuggle hammer tested his meth and taste tested his AP.

I always advocated using more stable and reliable primaries than peroxides. If someone is intelligent and talented enough to perform any real chemistry, peroxides are beneath them anyway, not to mention far too unsafe when you start looking at free energy diagrams and bond enthalpies.

How about HMTD? it is a peroxide and many more "pro" people in the explosives community use it.
If done well, properly neutralised and not stored for over a week, it is rather safe.

True, but it's SO easy and cheap to make, personally i've never used anything else for a primary.

OP, don't try to distill the 3%. If you can't get ahold of 30%, then purify the H2O2 via freezing. If you use a shallow container and throw it in the freezer for a couple hours, the water will ice over the top with the stronger solution remaining beneath it (assuming your freezer is right around 0 degrees F). This way you will eliminate the hazards of vaporized hydrogen peroxide and the pain in the ass of losing so much from condensation.

Cost vs. chance of death.

How much do you value your life?

HMTD is for people who haven't figured out that the dangers of AP aren't it's sensitivities and unpredictable nature rather than it's thermodynamic properties and chemical tendencies towards fucking you over on account of it being a bitch. Point to prove: whatever shit happens whenever cupper comes withing half an inch of the substance.

HMTD is more forgiving than AP, but it's still an organic peroxide. Safer than AP, yes, but you might as well make *that* peroxide if you're going for "safe", as neither of them really is.

It's like substituting sulpher for phosphorous in Armstrongs, it will only take off a digit *half* as often ...

that!

the differance between water and peroxide boiling is all of 8 degrees C if you can keep your temp below 108c but above 100c lol you should be A OK

I've only ever seen someone make the stuff once, but he just eyeballed some peroxide, nail polish remover, and toilet bowl cleaner (all from a dollar store) into an empty E&J bottle and let it sit in his fridge overnight. Dude got 200g of AP for something like $3. I guess the moral if the story is is source your chems cheap, and don't worry about the shitty yields.

AP is like the easiest shit to make. Someone had a little article how a marine in iraq managed to make some with no thermometer, no ice, etc etc.

wow the marine must be a genius ... pouring 3 liquid chemicals into a beaker !

and waiting !


lol bust out the metals

here's an old thread about concentrating hydrogen peroxide, specifically freezing it
http://www.totse.com/community/showthread.php?t=2077405

This is for the boneheads that want to boil down their 3% store bought H2O2 to increase potency, The inactive ingredient filling the rest of the bottle is distilled WATER!
The boiling point of H2O2 is much lower than that of H2O. Boiling this stuff will just waste away your peroxide causing harmful (explosive) gasses leaving you with water and stabilizing ingredients! If you have no common sense dont be making bombs!
If you must loose a finger or two then research distilling the stuff!

Ohh yea if your planning on ordering it through the internet research the site your buying it from because I have found several that are scamming people out of their money.

This is not the ACB, if we don't know what we are talking about here, we SHUT THE FUCK UP.

Yes, their boiling points are VERY close in dilute solution due to a near azeotropic mixture. Brute force boiling WILL result in a more concentrated peroxide solution assuming it doesn't all decompose due to dust, scratches in the container, too much UV ect. HOWEVER, simmering/evaporating at a temperature a bit below the boiling point of water WILL result in a more concentrated solution than boiling because one of the things that leads to the decompositions of peroxide is HEAT. This is NOT distillation, this is evaporation. Yes you will lose a bit of H2O2 as vapor in the process, thats a given. Sure its a fantastic oxidizer, but to assume the vapor along with the water vapor from boiling or simmering dilute peroxide to be explosive... is fucking retarded. Sure its not good for your lungs, but explosive? Fucking think. The limit for concetrating via careful simmering is around 25-30% IIRC. There is an azeotrope after that at which point you would need to use a different procedure to concentrate further. In addition by simmering and boiling some of the peroxide is evaporating away, so you will get close to the azeotropic limit, but always be a bit under it. Whats the saying? For approximately every 10C increase in temperature reaction rate nearly doubles.

Freezing works too, those few who have distilled their own HTP sometimes freeze concentrate the dilute stuff, sometimes multiple times. IIRC you can break the around 25-30% azeotrope this way, then concentrate further via vacuum distillation.

Both ways work. With both ways its hard to really know what your end concentration is.

Buy some fucking peroxide or abandon peroxides for safer more intellectually rewarding explosives.

LOCK PLEASE SO AS TO END THE CONTINUAL ADDITION OF RETARDED CRAP.

Yeah, that might be the best way to go.
