Working on my (somewhat) portable power supply. Considering what capabilities I want it too have. I have alot worked out in my head... DC to AC Inverter, volt and amp meters (or a "Watt's Up"), cig socket, speaker pinch terminals, a nice distribution block rated for about 25A, blade style inline fuses and spares, a couple of double throw safety switches, a solar charge controller (with bypass so I can charge/top-up the internal battery or an external one), likely an attached small solar panel to keep the internal battery maintained, a couple specialty 12v outlets... possibly even this really nifty potentiometer controlled variable voltage dc-dc step up/down converter with digital readout thats good for 3A... but yeah I'm running out of money fast... Just got a 33Ah 12v deep cycle battery today for it. I have most of the stuff to get a nice working portable supply running already, but I'm holding off a little longer so I don't go drilling holes that I'll regret the placement of later... ... and the coolest part is that all this is going into one of those army ammo cans that are air/water tight. :D
PGI was awesome. Stepped up to an 8" spherical shell. Hopeing for 10 or 12" next year :D. Also got some elusive damn reactive 1000mesh atomized titanium... made by spraying titanium into molten sodium I'm told. Some guy tried to ball mill a few grams of it by itself and it blew the mill up... :(
Have tons of peppers in the garden.
Extracted capcaisin from habaneros.
Got an "A" in Org Chem I.
Need a new car.
Thermoelectric cooler is jsut waiting on a suitable small power supply, then its done.
All I can think of at the moment.
I was feeling nostalgic the other day so I bought some simple OTC stuff to hopefully get some small things together in stealth. I never really did any advanced stuff because I'm still living with my parents but I missed the old days of sneaking out at 3am down to the park to set off AP :cool: . Dunno what chems are still available OTC, AN is well and truly gone I think however I have a supermarket that stocks 500g tubs with high AN content and I think I have perfected my method to extract a decent purity amount pretty quickly.
Hopefully the hobby store still stocks 99% NM, and I think it's time for some 6% H2O2 detergent AP synths :cool:

So my old man wanted a coloured solution, I decided to make some cupper sulphate.
Whipped out the sulphuric acid and hydrogen peroxide, stripped some wire and soon enough: lovely blue solution as well as a bunch of precipitated CuSO4 crystals.
when it came to neutralising the acid, I went on about it slowly, testing once every while with a pH meter and adding bits of bicarb at a time. The old mans patience ran thin, and he decided he'd go about it faster. Soon enough, we had a wonderfull GREEN pH 4.5 solution of cupper carbonate ... nothing a little extra sulphuric acid couldn't solve of course.

My anderson power poles and "Watts Up" meter have arrived! Going to go find a better crimping tool, some poplar to keep the battery in one place, and perhaps some nice thick hookup wire tomorrow. Dunno. Read about a good idea online. Heavy gauge hookup wire via car jumper cables. You can cut to length, strip, then crimp on a short length of copper tubing, pound the rest of the tubing into a flat spot and drill through it, then reinforce by soldering it all together if you feel so compelled to. I'm likely going to do something like this when I get a big battery back set up in the hopefully not so distant future.
I should pump some 3/4" crossetts this weekend... possibly make up some KP/crispies and KP/hulls... and probably mill some BP... doubt I'll get around to it though...

It's the second time that on this forum I found that, you guys on the other side of Atlantic sinth coper sulphate. What you use to protect your wineyards - grapes from peronospora? In Europe it's No1 chemical winemakers use to protect their grapes from warious fungical diseases. It's avalliable here in any agrycultural chemicals shop, much, much easyer than any fertilizer....
Solution of coper sulphate+hydrated lime is called Bordoux soup, main fungicide, necessary for any agriculture. Big, blue christals, damed cheap, buy 100 g or 100 kg - no question asked.
It sounds to me like one must sinth table salt.....

It's good to see PRRT back up, i was against it at first, but it really does become the lifeblood of this place.
I'm having fun with chem agian as well. I was finally able to synth some good trinitrotoluene that i was able to recrystalize from toluene. Durring the course of this nitration i discovered the all too pleasing smell of MNT. I haven't det'd it yet becuase i think i want to synth a larger batch to be more impressive later.
I've also been doing more work isolating pure elements. I've got some CeO2 and LaO lined up to isolate next, and i'm doing pretty good with my element collection. I have access to a lot of really cool equipment at my university that i'm taking full advantage of. I have keys to the department, so i have access to a few chems, fume hoods, centerfuges, glassware, x-ray equipment, etc, etc. So i occasionally do my own experments there at night and on weekends. It's a pretty sweet deal.
I'm also taking a Descriptive Inorganic Chemistry class that is fun becuase it's really challenging me. So now i know how to read and write names and formulas like:
Diammine(ethylenediamine)chromium(III)-μ-bis(dioxygen)tetrakisamminecobalt(III) bromide (Yes, one word exept for the bromide!)
It's an upper division chem class, and i really am having fun with it because it's getting me back into chemistry. We also have to do a research project for the class, so i'm thinking about trying to do it on explosives if that's an acceptable topic. I will of course need to narrow the topic to a specific group of explosives (preferable mostly inorganic) to research. Any suggestions for what would be the best group to ask to do it on? Fulmanates? Azides? Chlorates/Perchlorates? What would be my best topic?
See ya gus around.

I was gonna ask about this on here, any guesses? The default guess is always ANFO, as there is no way that they are gonna cook up a ton of the "Mother Of Satan".
How I love that name for it.
The article was just talking about the added Aluminum, so that was the "secret" ingredient. Big deal, people have been adding Aluminum to NG for over one hundred years to correct for the positive oxygen balance. That's common explosives knowledge, and it's clear that the reporter is over-dramatizing the strength and sophistication of that bomb.

Anywho, this doesn't really go here but I didn't want to clutter up the BB with my crackpot idea: If a batch of thermite was made with excess Al and a quantity of some metal phosphate, would the Al steel all the oxygen from the phosphorus thus putting out vaporous phosphorus? Would it work if Mg was used instead?

That reaction is endothermic, not exothermic, so phosphorus would not be liberated by that reaction. You need to mix a metal phosphate in stoichiometric amounts with a suitable reducer (carbon is usually used) and silica. You then need to heat that up to above 1000C to drive off the elemental white phosphorus.

You then need to heat that up to above 1000C to drive off the elemental white phosphorus.
Lay some explanation on me. I've read that procedure, but I thought that Al or Mg would be much better reducing agents than carbon. BTW, in the reaction you cited, what does the silica do? I always figured it to be pretty inert.
Also, at one point I think I tried to use Na3PO4 as the oxidiser in an Al flash comp. My reasoning was that phosphate sounded a little like nitrate, so it might be an oxidizer (this was a long time ago). I had to ignite it with a propane torch, but eventually it burned. It produced some pungent fumes, so I never did it again.
Using Calcium Phosphate the overall reaction is:
2Ca3(PO4)2 + 6SiO2 + 10C (1500°C) → 6CaSiO3 + 10CO + P4
You can see the reaction is extremely endothermic (needs a lot of energy to work) because the Calcium Phosphate / Silica / Carbon mixture needs to be heated to 1500°C in order to proceed. You need some chemical thermodynamics to really understand why, but this is because the total entropy standard entropy of reaction (ΔS°) will be negative.
You are right that Aluminum and Magnesium are better reducers than carbon, but those metals are a lot more expensive and energy intensive to produce, so industrially they are not used because carbon makes a lot more sense economically. The silica is used to capture the cations of whichever phosphate you are using. In the above case, the silica captures the calcium ions and reacts with them to form Wollastonite (calcium silicate). It is the carbon which then is able to free the phosphorus from its tetrahedral oxygen cage. Another reason why those metals are not used is because the heat of formation values (ΔH°f) are lower for MgO and Al2O3 than they are for CO. This means less energy is needed by the reaction to create CO than would be needed to create MgO or Al2O3. That’s why the reaction works better with carbon as a reducer.
I hope that explains it sufficiently, and I hope I remembered my thermo right . . .

I might be mistaken, but doesn't the P come out as a gas? Could all this be bubbled through water to cool it as opposed to some other condensation array?

Preparation of elemental phosphorus (14 pages)

I believe that atleast one person has done the retort method with mixed success and failure. I somewhat remember something about an explosion scattering chunks of white phosphorus all over his back yard or something similar. Its probably in that thread.
Edit: I was about 6ft from a stray 4" aerial salute when it went off last night. I'm fine, just got a couple brusies on my legs from dirt clumps. The two guys who were slightly closer got alot of cuts on their legs and Ti burns on their arms, but are also fine. Basicly a rack was full of chains of 4" salutes and one blew in the tube sending the others scattering around... one happened to skim accross the ground and landed under one corner of the table we were firing from. It completely screwed one of the 2 fold down table leg things (the aftermath was a mangled metal thing) and fucked up one of the firing systems... we had to switch out cables and use the second firing system to finish the show and there was alot of un-fired material that was left. The finale to the show was 30+ 4-6" shells of "flaming shit" stars and set the field on fire, but everyone knew this would happen and the fire department got a good work out... it also cleared alot of small duds that were in the field from the night before.
Also sorta assembled my power supply for my laser... but its not working quite the way its supposed to, so I'm going to have to get tzar to help me debug it...

I was going to make a new thread for this, but it's a straightforward enough question: Could an astrolite-equivalent mixture be made by using compressed anhydrous ammonia rather than hydrazine? I know the dynamics of dealing with a secondary explosive that has to be kept in a strong container might be awkward, but it has the advantage of not requiring a hydrazine synth. Just some dessicants, NaOH, NH4NO3, and dry ice (too condense the NH3).

There was a bit of discussion of liquid ammonia explosives a short while back...
Your not likely to be able to make all that much ammonia... Have you calculated the theoretical yield from your ammonium salt? Don't get me wrong, I would really like to make liquid ammonia someday in my backyard too, but its alot of work for probably very little product. You are going to need a whole lot of desiccant. I'd say bubble it though sulfuric acid to scrub the bulk of the water... BUT the ammonia would react somewhat too... and how much... I don't know.
As for VoD... I don't think it would be along the lines of astrolite... but lower around ammonium nitrate mixes... So you would be almost certainly better off just using the ammonium nitrate for ANFO... or if your wanting more speed ANNM... You could even try ANNMSA - (SA=sulfuric acid). The acid reacting with the AN forms some HNO3... and NM/HNO3 is quite sensitive and powerful. Axt at SMDB as done alot of experiments with this. But if your like me and can't readily get NM... then... meh... Perhaps ammonium nitrate / aluminum...

I get MgSO4 hydrate for $1/kg. It's easily dessicated by microwave, thus making vast quantities of desiccant readily available/cheap. During winter NH4Cl is sold commonly as a de-icer salt, making it also about $1/kg. As for NaOH, some have he benefit of living near good HW stores and can get NaOH for cheap as well.
As for the composition itself, I don't know if this would require excess of one reactant or the other (AN vs NH3), but theoretically, the molar ratio of NH3/NH4NO3 would be 2/3, the weight ratio being .142/1. What this means it that even if you pay the big bucks for your chems, not much anhydrous would be needed.
As for VoD... I don't think it would be along the lines of astrolite... but lower around ammonium nitrate mixes... So you would be almost certainly better off just using the ammonium nitrate for ANFO...
Really? I would think much higher (than standard ANFO), but then again, I have nothing to base this on.

Axt at SMDB as done alot of experiments with this. But if your like me and can't readily get NM... then... meh... Perhaps ammonium nitrate / aluminum...
Over at LT the idea of making nitroalkanes is fairly commonplace, although for something like ANNM, it might be more work than it's worth. I forget what the standard method is. But yea, ANNMSA? Sounds cool. I take it adding SA wouldn't work with a standard FO because of solubility issues?

2008-11-21, 05:36
Heres that thread:
http://www.totse.com/community/showthread.php?t=2161509
I guess that should work ok for your desiccant.
Yeah I have 4+ lbs of ammonium sulfate and I can get enough sodium hydroxide when ever I get around to getting more.
I didn't check for VoD, but it should be only a bit higher than AN / hydrocarbon fuels because of the higher density. Maybe up to 500m/s faster, dunno could be completely off.
Unless you can find nitromethane OTC cheaply ANNM is pretty much out of the question. I havn't read on making nitromethane in a year or so... but IIRC all common methods were too expensive for the hobbiest in terms of reactants and poor yields... BUT... you wouldn't have to use nitromethane... you could for instance make nitroglycerin... or ethylene glycol dinitrate and mix it with ammonium nitrate for probably very similar VoD. You would have to find a table of VoDs to check... but I imagine it would be pretty close.
Hmmm adding sulfuric acid to ANFO... some of it might react with the nitrate making nitric acid... then you have nitric an sulfuric acid and some of the fuel oil would be nitrated and water produced... So not so great. With HNO3/H2SO4/NM there is no appreciable reaction as I understand it.
Edit:
I didn't think of this until now... but you should probably add a water cooled condenser before your drying train... so you condense most of your water vapor and lead it away instead of having to pass everything through your dessicant. Some of the ammonia may dissolve into this water... how much i don't know. You could have it set up as a reflux condenser for the water... or vertical like reflux, but with a 3 way on the bottom so you can lead the condensed water away from the reaction pot. I really don't know which way would be better.

about 3 mLs. The acid is a catalyst, so the precise amount doesn't matter so much, just add it slowly and cool and stir. I find it easier to dilute the acid (acid->water, of course) about 2:1 with water and add it that way, as its easier to prorate.

I think it's not, because CoSO4 and CoCL2 are both soluble... so you have to look at the electronegativities, and... f*ck. I have to relearn polyatomic ions. I'll do it at work tomorrow. I like the new method though. Short and to the point.
@xarf Yes, but where does the hydrogen come from? And where does the Cl go, and what happens to the Co....
EDIT: It doesn't matter about polyatomics because they are both soluble. To do a double displacement one of the possible product needs to precipitate.

Depends on what you have available... since I have the sulfate, I tend to want to double displace to form something like calcium sulfate... or barium sulfate... which is really insoluble... Think strontium sulfate is around there too... I would probably choose the one with the emission spectra closest to cobalt so that if I ever used it for colored flames it wouldn't look horrible due to contamination...

Won't that produce heat and hydrogen gas?
Yes. And as long as I don't light up a smoke, I'll be just fine!

Hell no I went to Fort Benning HOME OF THE MOTHER FUCKING INFANTRY NIGGA!!!!!!!!! I had a buddy that went there. What your MOS? Trust me lost in the woods no were near as bad as benning, at least Infantry training compared to MP training was. Because talking to my buddy whos MP he had a lot nicer shit and freedoms, they got their cell phone after basic in AIT, had every weekend off, got to sleep in tents, got cots, got to drive humvees instead of humping it everywhere, got to be around a few girls(Some where hot saw pics), cameras, and many other shit haha.
89D :cool:
L. Wood for basic and Redstone/Eglin for AIT. Basic was easy, yeah, but our company set the brigade record for longest time in red phase. Was over 7 weeks of DS in week 1 day 1 mode. All those privelages and shit weren't given to us. AIT is a lot better than that shit. Yeah we did train with girls and had some nice ones too.

Nice that's cool how long is your AIT? That's probably one of the only other jobs id want to do in the army besides infantry, or possibly door gunner because who the fuck wouldn't want to rain down +3000rds of death a minute?
