NON-HE use of TACN in pyrotechnics?
I'm not sure quite where this falls in the realm of practical vs academic, but I figured this is a much better place to post the quesition than at
APC...
...Simply put, my holiday budget is running thin and the 4th is coming up soon - I've got reds, greens, gold, and silver stars down, but blue is
always elusive. A lot of older formulas use "copper ammonium nitrate" or "ammoniated copper nitrate" - Which, lacking a knowledge at the time of just
what it was, is the TACN that so many of you guys have played with in recent years...
...Question is simple - COPAE and Weingart's "Pyrotechnics" list a handful of blue star compositions that use TACN - Not sure if it's purely colorant
or if it contributes anything else, too much to do to spend the time to do the math out on it...
...Has anyone here worked with any of the TACN based formulae? Something tells me the blues may be quite true, but I've not long until showtime and
neeed to decide whether to spend a day preparing TACN or copper oxychloride - The former is much more desirable if nothing more than for the potential
speed of production...
If you see me running, try to keep up.

You are referring to 1,4,7-triazacyclononane right?
I just scoured Google and could find no reference to its uses in pyrotechnics. A lot of interesting uses as a tridentate ligand it seems.
"It is threefold symmetric and binds to one face of an octahedron of metalloids and transition metals. The (TACN)M unit is kinetically inert, allowing
further synthetic transformations on the other coordination sites." -wikipedia
U.T.F.S.E. and learn the joys of autodidacticism!
Don't judge each day only by the harvest you reap, but also by the seeds you sow.

No, he's referring to tetramine copper nitrate- the AN-based blueish-purple thing that people play with. Just because it's blue, it doesn't mean that
it burns blue. Being AN-based, it gets wet fast.
Google and YT it. It has no use in pyrotechnics.

Hygroscopic.
If your ammonia source is not pure, you will also have contamination. Perhaps even sodium contamination.
I don't think it is worth trying to use.
Black copper oxide (CuO) is readily available at many ceramic suppliers and generally works well for pyrotechnic blues.
If you want more replies, I'd suggest posting at APC as well, or at least searching and reading similar threads. Considering that your considering it
for color, not HE effect, just say that and it will be treated as such.
So many ideas... too few dealing with chemistry.

These are the tetraamaine's from The WiZard's Pyrotechnic
Formulary. [ 2 971 formula.]
Non of these tetraamine's as used — are explosives.
I have doubts 'bout hue and saturation. Please .... report back with your results.
As all use potassium chlorate I have doubts about
stability/safety.
