So I just obtained a gallon of HCL (31.45%).

-In an event where I successfully make trimer-

1.) From your first hand experience, how sensitive is this really? Can you provide me with some info about particulars about friction sensitivity, and shock sensitivity.

2.) How efficient would this process be? i.e. having 14.5g of H2O2, how much AP would it yield?

-i'm already familiar with static danger and I already have sprayed my lab with antistatic spray.

thanks

------UPDATE/PICS!!!!!!!!!!!!!!!!!!!!!!-------

ok, i'm one hour into the synth and i have 15ml of HCL into it, all while it was under 10C. It's starting to form what i THINK are crystals, comment please!

4/15/07- FAILED!!!

4/16/07- SUCCESS!!! synthed a total of 8grams. Video shows .1g deflagrating! finally! http://youtube.com/watch?v=fN1xkk6PGv4

Friction and impact sensitivity are scary. Grinding/crushing crystals of AP is the most dangerous thing you can do if you're not juggling it. ( )
I dunno about the efficiency.

Yeah AP is very sensitive. A simple tap from a hammer is enough. Packing it is always very scary.

So don't mess around with it.

As for static I never had any problems. I guess you could wear a ground lead while you're working with it if you were that paranoid.

What concentration is your hydrogen peroxide? 14.5g doesn't really tell me much unless you want me to do a bunch of calculations.

ha im making a good batch myself tonight.

14 grams wont get you very much, i think the acetone and peroxide react in a 1:6 ratio. i estimate if you made it in a graduated cylinder, you would definitely be under the 1ml mark. The amount of acid you put in also wont really matter either, as its just a catalyst. if you are only using a small amount of acetone and peroxide id keep it close to 1ml.

keep it cold by the way

Since you don't mention the HOOH concentration, we have no idea.. Just like resso says.

Also you don't mention your acetone at all, so we have no idea how pure that is.

Reaction time is important too, alot of people end up filtering the AP out before the reaction is completely finished. Doesn't hurt anything, just get that much less.



Most importantly, why do you want to make AP at all? What do you really want it for?

No, NO. H2O2 reacts with acetone 1:1. H2O2 has a density of 1.4, so 14 grams pure would be 10mL, not one. 1mL of reagents will yield just about nothing.

Personally I use about 11mL of acetone for a small batch, and this gives about 10g of AP. I like to let it sit in the fridge overnight.

No matter what anyone says about sensitivity, you really have to get a feel for it yourself. Take some about the size of a pinhead, and see what it takes to burn/detonate it. Repeat with another tiny amount. Don't work with anything larger until you get used to it, and you'll be fine.

Is it 3%, 5%, 30%?

These are things you need to know.

With sulfuric acid, I have been able to acheive near instant formation of AP from 30% HOOH and 100% anhydrous acetone. I just dumped it all in lol. Everyone discourages that hardcore, but I've done all kinds of tests using HCl with fridge compared to freezer compared to room temp, compared to constant low heat, and have noticed NO difference in product AT ALL.

So one day I had no HCl, only H2SO4, so I did my regular habit of dumping it all in, and it got fucking HOT as fuck, and upon cooling, BAM a solid fucking rock of AP. This product was ran through the regular tests after washing and drying, and there was still no difference between AP via fast hot sulfuric vs slow prechilled slow addition UBER FUCKING COLD HCl catalyst synth. Some of you may be like, no, but fuck you. I've seen it.

Oh yeah, double post, but the amount of catalyst DOES matter. The more you use, the faster it goes, but the more acidic the AP will be, so it must be washed many extra times. Remember to go slow when washing with very acidic AP. And wait to use bicarb until multiple washings later, and still, go slow. It can fizz, and just the idea of explosives fucking fizzing is scary, but it's all good, just go super slow. little bit at a time. never make large batches, always split it up if possible, etc etc this thread could be fucking huge with AP tips and stories.

I have shrapnel from the shit. Metal in my fucking palm. Lighting the tip of a ramrod used to pack APAN into det cord. The end was hollow, and had APAN packed in. I thought it was just a bit on the tip, a small tiny amount, not even thinking about the hollowness.I light, and CRACK, metal in my palm.Still there too. So fucking stupid. Could easily have been my eye. So don't play with this shit. It is death incarnate. By creating this shit, you are just ASKING for some stupid slip up to fuck you up for life. but, then again, fuck it.

AP made with HCl doesn't need to be neutralized. When it dries out the HCl evaporates. The danger from H2SO4 is the reactivity of the acid with other stuff, AP is actually more stable in acidic environments.

The H2O2 I have is in a 973ml bottle and 3%conc.

The Acetone is 100%conc and is labeled as nail polish remover.

And the reason I want to synth? I've been curious about chemistry for quite some time and ever since I witnessed my friends uncle (a former combat engineer) removing trees with ANFO, i've always been curious in how these devices worked, so this synth would probably give me some first hand experience when I head off to college.

-I forgot to mention that i'm likely mix the product into APAN because I heard it decreases sensitivity, but if you guys know of any primaries less sensitive than AP, i'm open to opinions.
