Im worried about my ap. I mixed up all the chemicals and put them into the cooler at 6pm pacific time on monday. Its now 4pm on wendsday, and their isnt even a hint of crystals. Is somthing wrong here?

Very....

crystals should start to form almost immediately.

Its 3% peroxide. Does hat matter?

Yep, it's fucked.

Even with 3% H2O2 you should see crystals within 24 hours.

And i folowed your directions too!
Anyone know why this might have happened? I was using diluted sulphuric acid, 3% peroxide, and pure acetone.

I have just redone my experiment. This time i used 200ml peroxide, 150ml acetone, and like 20 or 30 ml of concentrated sulphuric acid. The mixure got quite hot, but it cooled down.

"quite hot" is not following the instructions!

It's also possible that any small yield you did get is dissolved in the major excess of acetone you have!

I suggest you do a bit of reading before attempting this again.

How much of the diluted acid did you use? how diluted did you make the acid? cause if you don't use enough, or the acid is not strong enough, the catalyzing effet will not take place, thus making the whole thing take a VERY long time.

"If you must, do it with intelligent people, at least they know how to talk to the cops."

The first time I tried to make AP failed too, but that was because i did it in a plastic bottle (for better hiding abilities in the fridge), so the acetone reacts with the plkastic and the reaction is (excuse me for my bad language) screwed !!

The first experiment I did was with 100ml peroxide, 18ml acetone, and aproximitley 10ml of dilutid acid. This mixture stayed very cool.

The second time was done with 200ml peroxide, 150ml acetone, and 20 or 30ml concentrated acid. It steemed for about 1 second, but then it cooled off. This morning I checked the experiment, and I already have 3/4cm of crystals at the botom of my snaple bottle. Hurray!

why do you use so little acid ???
Whith those amounts of H2O2 (6%) and acetone, i use 50ml of 29% HCl ...
Is this done to keep the temperature low ?? (not starting the reaction so suddenly)
If yes, do you add more acid further on in the reaction ??
How long does the reaction take if you use so much less acid ??

Hey mark, just be careful...

Dont worry, I will be. Ive only made about
1/3rd of a film canister of ap, and I keep it damp. Im only making small firecrackers too. Their 1" long by 1/2" wide hanger tube crackers. Lots of fun, low danger(well, as low as it gets with ap).

Just out of curiosity, if something were to go wrong, would ap detonate in an open film canister if the film canister was filed 1/3 of the way?

[This message has been edited by mark (edited August 12, 2001).]

it all depends. (get ready this is going to sound wierd) if the AP initiated from the bottem then i would put money on the fact that the whole lot would detonate. BUT if the AP initiated from the top then maybe not. It all has to do with confinement man.

"If you must, do it with intelligent people, at least they know how to talk to the cops."

N, that makes perfect sense. Thanks.

1/3 of film cannister full of AP would certainly detonate in my opinion !!!
I make very small batches detonate (0.5g)in a very small plastic cup (still gives quite a blast) , it is practically the same as the 1/3 full film-cannister ...
Do you press it ? (because that would really make the difference)

I dont store it pressed, but I press my firecrackers.

On a stranger note, I put in to batches of ap yesterday. One batch was made with 200ml week old peroxide, 50ml acetone, and 30ml acid. The other batch was made with new peroxide, and 20ml acid. Today, the bottle with the new peroxide has a thick layer of crystals(3/4 of an inch) and the other bottle has hardly any. Weird, eh?

I also have a question on sensitiviy. I tested a week old batch of ap, and found it as sensitive as armstrongs mix! I put about 40mg of it onto a brick, and tapped it lightly with a hammer. Bang! My ears rung for a few seconds, which is odd because I lit about 300mg in a triangle firecracker, and the bang was poor. It took as much force to set of my ap as a paper cap. Is my ap so sensitive because its old? Because the mixture got hot durring synthesis? Or is this normal?

H2O2 decomposed on exposure to sunlight, the old peroxide has probably largely decomposed.

The week old AP is probably from the batch you totally fucked and got hot, so you'd have got the dimeric form of AP which is both more sensitive and less powerful (IIRC) than the trimeric form which you get if you follow the instructions carefully.

Thanks anthony. The batch I just made stayed cool, so I think it will be ok. Thanks again.

I have used months (for lack of a better word) old peroxide and it worked fine. Although it was stored in my room away from light. so it isn't really the time, it is more the conditions.

I've never had a poor bang from AP before (I can't keep it longer then a week unused ;-), I just made some Mr. potato-heads go BANG, it was great fun, mashed potato everywhere from only 0.5/1 gram of AP ;-)))

But I have noticed that when you hit AP with a hammer, it explodes much louder (keeping the distance in mind), does it detonates faster that way ???

By the way, lets talk yields, how much did you get from your reaction (amounts, percentages, grams) because I think I should get more out of the stuff I'm using (scaled-down makeshift arsenal recipe):
50 ml of 6% H2O2 + 37 ml of pure acetone + 12 ml of 29% HCl gives me 4 to 5 grams of AP (I have a lousy scale)

Well, my latest batch is definitley TCAP, and not DCAP. I can easily tell because the dcap burns with a small, semitranslucent orange flash. The new batch makes a fireball 3times the size with a dark orange flame. My new batch yielded about 3/4 of a film can of ap, which was promtly made into woppers(inch long minicrackers.) Im verry pleased.

hi there.

i was wondering,
how can i press AP to 1.10g/cm.

i'f got the trimer form but this is also very sensitive, how can i safe press the AP?

thanks.

The only way you can safely press ap is with a non-metal (Ex. dowel rod) Press it nice & slowly.
