Answered litteraly, that's going to be a very long list. Would this be an acceptable re statement, more or less meeting the intent of your question?

Quote:
Which single chemicals, themselves capable of being detonated have been COMMONLY used either as oxidizers or as fuels in explosive or propellant systems?


THAT could be answered in a reasonable space.


Yeah you're right. I should start thinking before writing something.

Not only commonly, but also viable for the home chemist.

Cheer up, there is life after fast foods. My head manager got as far as their management, before becoming a vegetarian and full time pyro and physical theatre/lighting professional. He is much happier now, and can tell you amusing and interesting facts about McDonalds, like "in a food fight, the guy with the tartar sauce gun ALLWAYS wins".

May I direct your attention to this thread?

Nice thread, looks like its exactly what I want.

Regarding mc donalds, I don't think I wanna be working there much longer. There is so much nastiness in the food that it makes me sick. I used to work in the kitchen, but now I'm just the bridge between the girl taking orders and the people in the kitchen, much better. I still feel sick when I smell the fat coming from the burgers and other stuff.

Potassium perchlorate isn't hygroscopic in my experience. I have never needed to dry commercially produced material.

Where did this perchlorate come from?

Feedme, your salt is not pure KClO4. You try test in water by 15 Celsia. KClO4 solubility = 1,5g /100ml H2O. NaClO4 solubility = 209g /100ml H2O. You can try your KClO4, for example 3 grams get into 100ml H2O. If will all solubled, is not pure KClO4. But the mix between both. Or even some else compounds can be in this.

Can you nitrate Pyridine?
I was wondering if it would be possible to knock off all of those hydrogen molecules and place NO2 groups there by means of an aromatic electrophilic nitration. I don't know if pyridine would oxidize or not, wikipedia doesn't say much about it, but it could be sulfonated first and the respectively carbon positions in which the RSO3− groups were attached would get replaced by the NO2.

IIRC, the direct nitration of pyridine is possible only using extremely high temperatures due to the pyridine (or pyridinium ion) not being very activated. Nitration of pyridine-n-oxide is more easy, producing the 4 nitro isomer (Attachment).

https://www.oc-praktikum.de/nop/en/instructions/pdf/1004_en....

From what I read, it is not possible to nitrate even the n-oxide to trinitropyridine n-oxide, although seems possible using an alternative synthesis from dinitroethanol:

-----------------------------------------------------------------------------------
Here is an idea I have been toying with for some time, any thoughts about this?

The piria reaction uses bisulfites at a pH of about 6-6.5 to reduce a nitrogroup to an amine. In some cases, a sulfonic acid group is introduced to the nucleus as well, desribely for nitrophenols in meta position.

I was therefor wondering what products would result if the piria reaction would be applied to picric acid instead? Bisulfite is a pretty decent nucleophile (Couldn't find any measure of this compared to CN-
or HS- though), would it be able to attack the picric in meta (position 3) and introduce a sulfonic group upon autooxidation of the presumed meisenheimercomplex? When I did a quick test, adding a spatule of sodium picrate to some bisulfite solution at a pH of 6.5 and heated it slightly, very quickly a very strong red-orange colour was produced. So it seems something is happening at least. When some HCl was added a dark orange brown developed. Might be interesting since, unlike thee reaction of picric with HS- and CN-, the reaction with bisulfite has never been characterized AFAIK.

Bisulfite is one of the reducing agents I had predicted would likely produce a picramate from a picrate. It would probably work even better with an added mole equivalent of NaOH to convert the bisulfite to the normal sulfite.

@ Bert No it was in reply to nitro-genes describing a red orange color from reaction of sodium bisulfite and sodium picrate, which probably produces sodium picramate.

The compound phenol sounds like it should be an alcohol. Apparently, it can form esters, like phenyl acetate:
https://en.m.wikipedia.org/wiki/Phenyl_acetate
So why doesn't the hydroxyl group on phenol/picric acid get replaced with a nitrate group during a nitration? My guesses would be
1. Because phenol "carbolic acid" and picric acid are acids, and thus do not become esters easily.
2. Because it turns to picric first, and the nitro groups take up too much space to allow HNO3 in to react with the hydroxyl group.
3. To make phenol acetate, you apparently need acetic anhydride. So does that mean that TNP mononitrate might possibly be formed using dinitrogen pentoxide? Thanks.

The hydrogen on the hydroxyl group of phenol is slightly acidic due to the electron delocalization of the benzene ring, so a nitration on the hydroxyl group is similar to trying to chlorinate the hydroxyl of acetic acid with HCl; a strong acid won't react with a weak acid.

AN Based explosives


Hello, I think some of you may have seen some of my tests on YouTube, I study chemistry and I have a good knowledge in the field of Explosives.

I am here for suggestions of compositions based on Ammonium Nitrate ( AN ) , I have tested many of them
ANNMAl
Ammonal Versions ( With Mg , Sulfur , charcoal powder , sugar )
AN + Mg powder
ANNAPHAL ( AN , Naphthalene and aluminum Powder )
ANFO versions ( ANFO + Al , ANFO + 2% Zn powder , ANFO + C )
AN + Ethylene glycol
AN + Glycerin
AN + Sulfur
AN + C
ANUNAL ( AN , Urea Nitrate and Aluminum powder )
AN + TATP
AN + Hexamine and with Al powder
AN + sugar
AN + Urea
AN + Nitric Esters + Al powder
AN + H2O2 Water gel ( Stable Mix )
The top 10 better compositions are 1° AN + Nitric Esters + Al , 2° ANNMAl , 3° AN +H2O2 Water gel , 4° AN + TATP , 5° ANNAPHAL , 6° ANUNAl , 7° Ammonal + C , 8° AN + Ethylene glycol , 9°ANFO + Al and 10° AN +Hexamine .

Tell my any other Composition AN based ((( without Nitric Esters !!! or Nitrocompounds ))))) !

It is always welcome new suggestions, of course someone with advanced knowledge about tested something that I have not had in mind yet and can be quite interesting for me .
I have many ideas but I want to hear what others have in mind, who knows is something I never thought of before, with Ammonium Nitrate the possibility is almost infinite!

I seem to remember some axt(number I don't remember) on at least two publicly available online platforms demonstrating ANNMSA (SA=sulfuric acid) and IIRC ANNMAlSA (no idea how the Al did not react with the acid, maybe my memory is failing me) had a much improved vod as witnessed in a metal plate test. These mixtures preformed slightly less than NANM (NA=nitric acid) which these previously mentioned mixes make except they contain inert ammonium sulfate.
On what basis did you make your top 10 list?

In the power ( Brisance ) and noise of explosions in my tests, I like to compare so I'm sure of the power of each one to another Composition .

How about simple ANFO? AN/ kerosene, Diesel or heating oil. Soybean oil is said to work also but requires a long soak time(1 week) there are several AN/ hexamine combinations too. Also adding laundry powders to some compositions can help the power. Have you read this?

Ammonium nitrate/gum spirits of turpentine (old fashioned turpentine, distilled from pine stumps, etc.)

Ammonium nitrate/DMSO or other fuels capable of quickly and completely dispersing through solid crystals of AN.

Ammonium nitrate/trichloroethylene

Ammonium nitrate dissolved in water with a fuel such as ascorbic acid, erythorbic acid, alginic acid or their salts and then dried.

Ammonium nitrate/hydrazine (Yo, astrolite?)

Ammonium nitrate/amine, such as dimethylamine, ethylamine, etc.

I am going to try in next week intermolecular mixtures, AN samples with ammonium benzoate, benzoamine, benzonitrile, ammonium acetate, ammonium phenolate and mainly ammonium thiocyanate it can give directly into the molecule Oxidant of AN the energy and reactivity it needs to ensure high VOD .

Gellatinizing power of NC


Hello World,

Can someone explain to me (or point me to a source where I can find such information) what are the critical parameters that define the gelling power (if used with NG/ EDGN mixture as the "solvent") of nitrocellulose and how - if at all - is this characteristic related to viscosity of the NC solution in e.g. acetone (i.e. is it justified to asses that high viscosity NC will give stiff gel? Or these properties run parallel but are not directly related, so one cannot predict the gelling power based on the viscosity of the solution)? I really couldn't find any in depth info about the gellation power of the NC beside the information given in Naoum's book.

Thanks in advance,
