Maybe you've noticed that I haven't included any <strong>Energetic Materials</strong> (EM) topics in my compendium. The main reason for
this is that it's a subject about which I know next to nothing. Therefore, I'd like an EM specialist volunteer to help me gather and organize topics
for an EM-specific compendium. You won't have to worry about the coding or formatting (I'll take care of all that), just selecting and arranging the
<a href="http://idioms.thefreedictionary.com/cream+of+the+crop" target="_blank">cream of the crop</a> <img src="../scipics/_ext.png"
/> topics.
So, who would like to fill the role of EM <a href="https://en.wikipedia.org/wiki/Archivist" target="_blank">archivist</a> <img
src="../scipics/_wiki.png" />?

So you write for wikipedia? Thanks, once I've spend so much time on wiki. You can use directly information from respectable books and experienced
forum mates can edit and suggest things. Wiki has quite a bit of inconsistencies and errors on EM.Dornier 335A - 8-10-2013 at 11:14
Why are you talking about Wikipedia? Bfesser wants someone to gather EM topics for his topical compendium.
I'll do it
Praxichys - 18-10-2013 at 05:26
I can devote some time to this. I may not be able to work very quickly but I do know my way around energetics, and I really think it would be great to
put the spotlight on some of the exemplary work our members have done.
Do you have an organizational configuration in mind? It could be organized by compound alphabetically, but under two major categories: theoretical and
synthetic. The former would feature excellent references regarding modern research compounds, and the latter for actual spoon-in-beaker, pictographic
syntheses.
Personally I would perfer that topics be organized roughly by general classification, i.e. benzene-derivative based, those derived from polyols, salts
of hydrazine and ethylene diamine, those based on metals, caged nitramines, those based on guanidine, etc. Each entry could be color-coded to let the
user know which topics are nonexistent, purely theoretical, or an actual demonstrated synthetic route.
I will play with some different configurations and we can go from there. Do you plan to add it to the current compendium? Otherwise I will create a
thread in Energetic Materials once I have a substantial amount built, and you can do the locking and "sticky-ing".
As a last note, I'm not sure I have the ability to edit the first post in a thread, so you may have to perform updates for me.
Updates to follow,
Praxbfesser - 18-10-2013 at 09:38
Praxichys, thank you. I'll forward you some U2Us that I sent to the previous volunteer, who hasn't logged in for a few
months—hopefully he didn't blow himself to pieces.Praxichys - 18-10-2013 at 11:25
Thank you, Bfesser. I have recived the U2Us and updated accordingly. Was there an old outline anywhere, or is that it?
EDIT: Since the edits will be occuring with great rapidity this weekend, I will refrain from creating the actual thread until it contains a reasonable
amount of information. I should think Sunday would be a good day to do that.
[Edited on 18-10-2013 by Praxichys]bfesser - 18-10-2013 at 12:06
That's all chemcam and I had come up with for the outline. Like I've said, I really don't know the first thing about EM. I know not
to add peroxides to acetone and not to distill propan-2-ol or diethyl ether to dryness, but that's about the extent of my EM 'knowledge'.
I look forward to seeing any progress on this. Please, don't hesitate to post tentative work. Hopefully the EM nutters will appreciate all that
you're doing as much as I do. Good luck!
[edit] I mean "EM nutters" as a term of endearment. It was pointed out to me that it could be interpreted as "adversarial;" which was never my
intent!

First I want to express my thanks to you for doing this job and bringing some order in the chaos of all the threads.
Maybe you could add a path for energetic salts, e.g. perchlorate or nitrate salts of the bis(ethylenediamine)copper(II) complex. You have entries for
ethylenediamine-based energetics, but having multiple paths to the same entry is not a bad thing.
Another thing may be to have some bad k3wl-threads in the compendium as well, as examples of how things should NOT be done. Such a set may be a
awrning at two levels, the first level being safety of the person who performs the synth or experiment, the second level being the the (im)maturity of
the post/thread.Praxichys - 21-10-2013 at 11:36
After all the years I've benefited from lurking on SciMad, I feel good being able to give something back.
I think those two very good suggestions. I have modified the outline accordingly. I will incorporate the remainder of the ethylene diamine salts after
further research, unless you have suggestions to that effect.

Great job so far will be really handy when it is finished
This has nothing to do with this thread but does anyone have a video of the guy detonating the 1kg of TATP? That would be a great addition to the what
not to do section.The_Davster - 22-10-2013 at 16:49
I would suggest the moving of "dried picric acid" from disposal to "common misconceptions"
Under common misconceptions you also have flashpowder detonation. I am not sure the science is actually settled on this matter.
Tetrazoles is far more diverse than salts of aminotetrazole . Nitro, azido,
nitrimino, azo....

Excuse the book, but...
Praxichys - 23-10-2013 at 07:00
Picric Acid
I had thought about that category for picric acid but I think that would mostly deal with corrosion of metals in the vicinity of picric acid, like a
steel screw cap with a perforated liner that has accumulated picrate salts of unknown sensitivity over time, or maybe to discourage the use of brass
bodies for caps containing TNP. I do know that the British in particular had "Lyddite" filled shells, which was TNP, but had issues with picrates
forming and would varnish the inside of the shells before filling.
I agree that the frequent bomb-squad dispatches for TNP are quite unnecessary. At this moment I store a small amount of TNP, dry, in a plastic
container with my other reagents. By itself it is ridiculously insensitive, enough that for most practical use it can be handled almost like a
non-explosive.
Therefore I think it would be prudent to change the scope of the TNP disposal to something like "Accidental metal picrate formation", and add the
bomb-squad-to-university publicity shenanigans to "Common Misconceptions". Does anyone know just how sensitve common metal picraes are? I am not quite
sure.
Flash Powder
Good catch. I will remove this. Something FP-related that might get added might be the "Fraction of a stick of dynamite" classification of flash
powder salutes, provided that I can find a thread about it.
Tetrazoles
I am not well-versed on this subject. I will have to use a search engine to figure out all the tetrazole compounds previously covered by SciMad. A
cursory Google search reveals that I have missed a whole lot in this category! Updates to follow.
As always, input is valuable to the creation of compilations such as this. Thank you!
PraxPraxichys - 10-12-2013 at 09:23
At (long) last. More updates. Plugging away at it...DubaiAmateurRocketry - 10-12-2013 at 20:06
Hi Praxichys, what about energetic binders/plasticizers? It is an important part of propellants/ polymer bonded explosive.
You can make something like azido polymers, azido plasticizers, nitroesters plasticizers, epoxides, eutectics, conventional binders etc... just some
examples.Praxichys - 11-12-2013 at 07:40
@DAR - Thank you for the feedback!
That is defiinitely a possibility, but keep in mind that the job of an index like this is to showcase the best threads pertaining to a specific
compound/subject.
I'm not sure that we have threads involving those materials that aren't merely speculative and ill-referenced discussions at this point. While
speculation is certainly valuable, the aim of this compendium is to provide detailed, referenced, and tested information regarding each subject as a
sort of "cumulative experience list."
This is not to say that I haven't missed anything. If you have any threads in mind, I will certainly review them and add them to the list.
Furthermore, if you can dig up papers about those subjects and upload them to SciMad, I will certainly add them as .pdf links.
Praxbfesser - 11-12-2013 at 10:41
I just want to thank you again for the time and effort you've been putting into this. It's appreciated. Dornier 335A - 11-12-2013 at 14:06
- Note that many topics or references to threads are listed as reminders to myself, and that most of these will change when the links are inserted.
- Please post all suggestions below.
- This list is really long and has a lot of breaks. This is so I can edit the maddeningly tedious PhpBB tags without going blind or insane. The spaces
will be condensed as much as possible when the list is done.

Sorry for the double post. Can I get a mod to drop this into the sticky?EF2000 - 29-6-2023 at 08:57
I think that Encyclopedia Of Explosives And Related Items should be added to the Further Reading section. Here is the
complete edition on the archive.org: https://archive.org/details/Ullmans, all 10 volumes in one place. (There're also separate volumes uploaded more officially by DTIC). (I hope it doesn't counts as thread necromancy)
