Er, you should know better than to do something like this and expect a valid reply. The chromatic responses of different monitors vary widely, unless all users have calibrated their systems with the correct color profiles (I have, but have you?).

Sorry for writing in a very old thread!

Yesterday i tried to make TACN by dissolving 2g pure copper and 5g ammonium nitrate in 10ml 10% ammonia sulution.
After 1 day the solution turned blue and bright blue crystals formed at the copper. I filtered the solution and ended up with 0.7g with crystals. I dried them well. Then i tried to detonate it. It got a very little "poof sound" and some smoke came.
Is this TACN? If so, it didn't impressed me!

I also tried to use CuO insted of pure copper. I ended up with some very dark blue\purble crystals after i filtrated it. When i heated them up, nothing happend. What is this? What did I do wrong?

Can somewhone give me a recipe with CuO and one with Cu to make TACN? It is so little info on these explosives on the internet! I have access to most of the chemicals and equipment used. And yes, i have read this thread and i have searched.

Well maybe it's a useless comment but isnt TACN just a pointless pursuit.
It has no practical use what so ever.
It's a bitch to dry, i made it under absolute alcohol with dried gass and every possible way i could think of to eliminate water still the damn stuff remains wet, which ruins it's properties if it has any.
Except for educational purpose i can not imagine why one would want to make it.
Better look for other complex primaries.

Try bubbeling dried ammonia gas through the solution.




What a fine day for chemistry this is.

Thanks.

In the Copper, ammonium nitrate? Can i mix copper and ammonium nitrate in ethanol and bubble ammonia through?
Can i boil 10% ammonia to get ammonia gas or must i do it another way?

"Well maybe it's a useless comment but isnt TACN just a pointless pursuit. It has no practical use what so ever."

I have to disagree. TACN is easily dehydrated in dry acetone, forming a stable dull-violett powder. This is the only useful form of TACN. The hydrated form cannot be stored because it readily draws CO2 from air. It is also very insensitive and weak. I observed the same effect with TACP: The hydrated form is useless. It can hardly be ignited with a match and is very insensitive to impact. Remove the water of crystalization and you get a much more sensitive and powerfull substance. Of course these materials must be stored in a well stoppered bottle to exclude moisture. Thats probably the reason none of these substances ever saw commercial application as primaries.

"It got a very little "poof sound" and some smoke came.
Is this TACN? If so, it didn't impressed me!"

Yes but its the hydrated form. From that you will hardly get anything more impressive than a pop sound and some smoke. Plus it decomposes in air. So you need to dehydrate it. Put the crystals in a beaker with dry acetone, crush them carefully then decant and press dry between filter paper. Let them dry in warm air until all acetone has evaporated. Then do a final drying over CaCl2.

During the acetone wash you will notice the chunky crystals change color from deep blue to a light violet and turn into a fine powder. This powder is stable in air and quite powerful. Its quite sensitive too - smack with a hammer and it goes boom.

"Can somewhone give me a recipe with CuO and one with Cu to make TACN?"

Both will work. NH4NO3 can oxidize copper metal, forming ammonium nitrite, ammonia and water. The nitrite is unstable @RT and decomposes to water and nitrogen:

Cu + 3NH4NO3 > Cu(NO3)2 + 2NH3 + 3H2O + N2

Only 2 moles of NH3 are formed per copper atom. Four NH3 will coordinate to Cu(II) forming the tetrammine complex:

Cu+2 + 4NH3 > [Cu(NH3)4]2+

The nitrate [Cu(NH3)4](NO3)2 can be precipated because it has a much lower solubility than copper nitrate.

As you can see, oxidation of Cu with NH4NO3 will only give 50% theoretical yield because too little NH3 is formed. You can remedy the situation by boiling Cu metal in NH4NO3 solution, then add ammonia. Work with hot concentrated solution, if possible use dry NH3 gas and lead into the still hot solution. Upon cooling you should get a nice crop of TACN.

Of course CuO works better because copper is already oxidized. No waste of the precious nitrate ion here. Put copper metal into ammoniacal NH4NO3 solution and bubble air through it. Copper is oxidized on contact with air, the oxide dissolving in water:

2Cu + O2 > 2CuO
CuO + H2O > Cu(OH)2

"It's a bitch to dry, i made it under absolute alcohol with dried gass and every possible way i could think of to eliminate water still the damn stuff remains wet, which ruins it's properties if it has any."

It cannot be made in anhydrous form, unless you have access to anhydrous copper nitrate :) This stuff is not easily available and quite impossible to make at home.
If you start from CuO or copper metal, the reactions forming the complex will always produce water so theres no point in using ethanol as medium.

I've made it under professional lab conditions as well as TANN with "every" possible material/chemicals within my reach .
And besides i used no water at all ( as far as that's possible with moisture in the air ).
The only contact it had with water was during vacuum filtering.
Well what I am actually trying to say is that its funny substance to make but it remains pointless.

Ps. is not there a topic about this like 20 pages long?

I really appreciate your post Taoiseach!
One thing I did not understand was how to dehydrate it in acetone? Can you describe the dehydrate procedure a little clearer, I'm not so good in English.

Dump it into a beaker filled with acetone, stirr and let it sit for a short time. The acetone will take up the water of crystalization. Pour off the acetone (which now contains water) and wash with another portion. Repeat until the color of the crystals no longer changes.

Of course this works best with dry reagent grade acetone, but I tried it with the crappy comercial stuff (which contains a considerable amount of water) and even that worked fine.

Yes its possible thou not very economical.
You can also use an ammonium salt e.g ammonium nitrate.
Just pour some acid over it and you will have ammonia gas.
The only problem is that the gas might be wet so it has to be dried over a desiccating salt/fluid.

NH4NO3 + HCl --> NH4Cl + HNO3
HCl is the strongest acid i have, so how can i make ammonia gas the?
Can I use acetic or citric acid?

I have not taught me everything in the chemistry yet, but I know a lot about it. My father worked on it, so he can very much. He helps me too!
So you don't need not be angry.

I have dehydrated the crystals in acetone and dried them with Potassium Chloride (10h). I testet them, but they didn't detonate! The acetone was 60-100% and the container i dried them in with potassium chloride is airtight. What did i do wrong?

Are kidding me?
How do you dry stuff over KCl, its not like that hygrospopic.
Wow and btw that would be an awsome way to make HNO3 :o

I buyed KCl on a hardware store as a stuff to dry things, so I thought I could use it.
NH4NO3 + HCl --> NH4Cl + HNO3, i copy and paste it from another site. I thought it was too easy to make HNO3 that way too, however, it could be that NH4NO3 + HCl --> NH4Cl + HNO3 was right, but it was impossible to make HNO3 that way for some wierd reason.
Don't look at me like I'm stupid!

how can i dry the crystals then?

It is possible and HNO3 is in the mix of NH4NO3 + HCl aside with NH4Cl; but to get HNO3 out in appreciable amount is another story because HCl is more volatile and because by concentration of the watery solution HNO3+HCl will make ON-Cl and O2N-Cl and oxydise the NH4(+) into N2, NH2Cl and NCl3 (+ some Cl2)...

There you see :P

I have got some calciumchloride to dehydrate my TACN. How long does this take?
It has stood for three days, however, nothing has happened. Another person from another forum has let it sit for over a week and the TACN has turned brownish? He has not yet testet it, though.

For TeACP procedure is almost the same as for TeACN. In the clip, the only difference in the ratios. The clip is also an attempt to what can be cut only with youtube editor. But this is off topic EM.
