1,3,5-trichlorohexahydrotriazine
I made my first energetic compound!
I do not really like energetic compound but following a post of franklyn I found an energetic compound that I wanted to try.
http://www.sciencemadness.org/talk/viewthread.php?tid=2945&page=3
The process was not well explained, but the general idea was that if hexamine is reacted with NaOCl/CH3COOH mix it will make
1,3,5-trichlorohexahydrotriazine ( C3H6N3Cl3).
Experimental:
(I did all the process outside)
2.5g of hexamine from coleman fuel tablet was disolved in 25ml of water. Then 30ml of 10% sodium hypochlorite (pool chem) was mixed with 40ml of 10%
acetic acid (cleaning vinegar). After pouring the NaOCl/CH3COOH mix in the hexamine sol. the solution turned cloudy white, I swirled and suddenly a
yellow flocculent formed on top. I filtered it and take a pinch of it and try to dissolve in water but iit was insolube in water, so water was a
perfect solvent to clean the product. I cleaned the product with water and I lets it dry. After drying I deflagrated some of it, It burn instantly
making a pop sound, success!
Maybe I will try to make a salt with this compound.
Description of the product (from my own analyse):
Yellow material insoluble in water and smelling chloramine.
Thanks!
I never asked for this.

Sorry for the double post.
This compound seam to be very energetic when dry. The product take some time to dry but when it is completly dry it is quite impressing for someone
that never made energetic compound. The compound is solube in methanol.
The most impressive with this compound is the OTC(ness) of its starting material.
edit:
I'm precipitating a bromo variant. More info on the process/reactivity soon.

If you are willing to experiment , I'm wondering if RDX can be achieved by this
method. NaNO2 sodium nitrite is also very soluble in methanol. Mixed with the
compound you have made and promoted with some lewis acid catalyst such as
CuCl2 copper chloride , it could result that NaCl would precipitate out producing RDX.

CH2 . . . . . NCl . . . . . + 3 NaNO2 => 3 NaCl + C3H6N6O6

Those of you with more knowledge of synthesis please contibute your opinion
and critique this. It's been a nagging thought for too long.
Hypothetically NaClO3 sodium chlorate is also worth trying , possibly yielding a
Perchloramide >NClO3

I'm willing to experiment but I do not have sodium nitrite. I have sodium chlorate.
The product generate chlorine when in 30%HCl probably this reaction is appening:
6HCl + C3H6N3Cl3 + 3H2O -) 3Cl2 + 3NH4Cl + 3CH2O

NaOCl can by bougth at the hardware store as ''liquid chlorine''. If you cannot get some look for 65% calcium hypochlorite or '' shock chlorine'' for
pool it should also work.

That is an intiguing question. One thing for certain, however, it would not work if there was any water present. The chloramine would act like a
bleach and the nitrite would get oxidized to nitrate.
I am not entirely sure how the N-Cl bond would behave in nucleophilic substitution reactions. Although the N-Cl bond can readily hydrolyse in water,
it could be much less reactive in an attempted substitution reaction with nitrite.
I believe this may be anologous to the reactions of haloalkanes with sodium nitrite. Chloroalkanes generally do not react, while bromoalkanes are much
more reactive. Remember, the proper solvent needs to be used, which is both non-nucleophilic (generally water is not optimal) and can dissolve the
sodium nitrite. DMSO is a good solvent for this. If trichlorotriazine is unreactive, you might try tribromotriazine.
You might see this reference:
http://www.sciencedirect.com/science/article/pii/S1044030500...
It mentions that nucleophilic substitution on chloramine to form chloride ions proceeds at a rate more than 100 times that of chloromethane, which may
still be rather slow. Consider for example that the hydrolysis of chloromethane with water takes around a whole year!

Anhydrous chloramine is an extremely hazardous (toxic and explosive) and unstable (decomposes at −50 °C) compound. Therefore, it was prepared
in situ in an aqueous solution according to the modified Raschig method: Aqueous ammonia (30%) and a solution of sodium hypochlorite (11%–13%
available chlorine), both chilled to −18 °C, were mixed in a 1:4 ratio by volume (a slight excess of hypochlorite) in an ice/NaCl bath. The
resulting fresh solution of chloramine (10 mL, ≈3 M; kept in an ice/water bath at 0 °C) was immediately used for experiments

Like I said earlier I'm willing to experiment but i do not have NaNO2 or DMSO solvent. I could buy some...
At least I could make anhydrous aluminium bromide as a catalyst.
I also tried to make bromo variant but it did not seam to work... I will make hypobromite soon and attempt to make it again.

Not sure if the below relates to this topic:
Quote: |
The nitration of aliphatic secondary amides and of primary and secondary aliphatic amines has been studied extensively and some understanding of the
reaction is now at hand. Firstly it has been found that the ease of nitration in acetic anhydride varies inversely in respect of increasing base
strength. Secondly those strong amines which cannot be nitrated directly can be converted to their nitramines via the intermediate preparation of the
chloramines, presumably because the chlorine substituent reduces the base strength of the amine. In many cases the chloramine may be prepared in situ
in the acetic anhydride - nitric acid medium by adding a small amount of hydrogen chloride. The hypochlorous acid thus produced forms the chloramine
and is regenerated when the chloramine is converted to the nitramine. A chain reaction is thus developed which is largely self-sustaining. Finally
primary amines, which cannot be nitrated directly, may be converted to primary
nitramines via the primary dichloramine. The alkylchloronitramine (which can be converted separately to the alkylnitramine) is the actual product of
the latter reaction. This is fortunate because primary nitramines decompose in nitration media, often violently, in strong sulphuric or nitric acid.
In acetic anhydride or acetic acid the decomposition rate is dependent on the amount of excess nitric acid which is present.

I tried this little experiment as well, but I obtained a white flocculent solid, on top of the liquid. As Plante1999 said, the liquid first becomes
opaque and white, and after swirling a flocculent solid is formed which moves to the top of the liquid. This solid, however, is white in my case,
white like snow.
@Plante1999: What kind of vinegar did you use? Was it clear colorless, or some colored and spicey stuff? In my experiment I used diluted acetic acid
from a chemical supplier and I used plain household bleach for the hypochlorite. I used purified hexamine, recrystallized from so-called ESBIT solid
fuel tablets. The hexamine I used has a fishy smell. Maybe the yellow color you observed is due to some impurity?

My hexamine was from Coleman fuel tablet, 12.5% sodium hypochlorite and 10% house hold vinegar. But I think you are right since washing the product
with excess water give my a white floculent solid and a yellow solution. I think the impurity is chlorinated organic since they are quite volatile,
the yellow solution turn colorless in a few hour after the reaction.
I never asked for this.

I think it would be much preferable not to use vinegar. While vinegar and bleach certainly can form some hypochlorous acid in solution, the acetate
(from the vinegar) may be vulnerable to oxidation.

The vinegar is essential. Without the vinegar, no precipitate is formed at all. I tried that as well. Any weak acid will do the job, as long as it is
not oxidized by the bleach. Acetic acid is suitable, it resists oxidation very well.

Well I just scored some NaNO2.
I am going to try making some trichlorohexahydrotriazine.
Plante1999 and Woelen .... Did you find any significant gas evolution or fuming besides the smell of bleach ?
Reason I ask is .... I reside in a fairly populated area with houses and lots of neighbors.
Smell of bleach .... No one cares about.
I am going to use 5% vinegar and hypo and double the amounts.
Thanks

I am somewhat disappointed. It so happens I was at the uni library digging up papers on organic reactions with hexamine. My first thoughts were how
closely it resembled trichlorotriazine (cyanuric chloride), a powerful chlorination reagent which can substitute for thionyl chloride and PCl3 and has
the additional advantage of being a solid.
As above mentioned compound, trichlorohexahydrotriazine, is very closely related I was hoping to find similar capabilities for ths product.

This process gives off quite some nasty smell. It is manageable, but I would not like to do it in a crowded area. There is a very peculiar smell, not
like bleach, but much more pungent. It probably is due to formation of some chloro amines. The hexamine I used has a fishy smell (it always has, due
to formation of trace amounts of methyl amines) and I think that the chlorination of these leads to the nasty and choking smell. You could try it on a
testtube scale first (e.g. 1/10 of the amounts, used by plante1999).

Woelen .... Thank you for the heads up.
I'll try just reacting a quarter tablet or something.
Will let you guys know what happens...
I have this weird gut feeling that only 1 or 2 out of 3 N-Cl will convert to N-NO2 by treatment with NaNO2 in MeOH.
Just seems too easy. Only one way to find out if it will work or not.

the preparation of methylenediamine salts* by the action of an excess of strong acid
on methylenediformamide at low temperatures. When 77 grams methylenediformamide
were added to 500 grams concentrated hydrochloric acid at approximately 12°C,
[ Knudsen 64 ] obtained 57 grams methylenediamine hydrochloride, CH2(NH2)2-2HCl
as a crystalline precipitate. Formic acid is obtained as a by-product of this reaction:
* Methylenediamine is of particular interest since it is the ammono- analog of
methylene glycol. Knudsen found that salts of this diamine are stable in the dry state
and, in addition to the hydrochloride, prepared the nitrate [ CH2(NH2)2.2HNO3 ]
and the sulfate [ CH2(NH2).H2S04 ] by reacting methylenediformamide with an excess
of concentrated nitric acid and 50 per cent sulfuric acid, respectively, at low temperatures.
The nitrate of methylenediamine crystallizes in prisms, which melt and then explode
when heated on platinum foil. Attempts to prepare methylenediamine itself by the action
of alkali on the hydrochloride were unsuccessful, since the pure base is apparently
unstable in the free state. However, when it is liberated in the presence of alcohol,
solutions of methylenediamine are obtained and, according to Knudsen, are sufficiently
stable for use in chemical reactions.
