Storage Stability
Not sure if there is another thread for this but I figured I would just document it in my original thread.
A sample of CHP and TACP that I made using this threads help is now over 4 years old. The CHP is only around 5 grams, completely with out the smell of
ammonia now. Was stored in a normal prescription pill bottle (USA not sure if they are different else where). Showed no obvious signs of degrading and
seemed to have the same energetic properties as the day it was made and tested. Was not able to test if the CHP was still able to detonate yet, I have
a strong feeling it will. Will update when Im able to test.
TACP still had a slight smell of ammonia, much less then it started with. It was around 50 grams so I image it was able to hold the smell better. Same
as the CHP it showed no signs of degrading and all the energetic properties you would expect.
ETN - Might as well document this as well. Small sample of ETN also around 4.5 years old. Still bright white, and burned as expected. Strange smell,
sort of like a chlorine pool. Anyone else have experience with long stored ETN? Would love to hear if this is normal.

ETN should not have an odour. Some people perceive NOx as a chlorine type odour. There is a decent chance that your ETN has somewhat decomposed.

I can give you my experience. Im long term testing some samples now.
I have a sample of CHP from a while ago, probably over a year, maybe 2? (not sure). Sealed in jelly jar. It has no signs of decomposition and is
stored in an area that goes from below freezing in winter to above 90F in summer.
I have a sample of ETN twice recrystallized from methanol stored in a washed out aspirin bottle. It was two years old and began to decompose releasing
NO2 gas which could be seen in the bottle when the lid was removed. The smell is a chlorine smell but a little more sharp and pungent almost like a
mineral acid or HCl. The material in the bottle was then covered with water and is continuing to store in a liquid slowly evaporating. I am monitoring
its decomposition and H2O remediation. I also have a sample of PETN twice recrystallized from ethanol. It was made at the same time as the decomposed
ETN. The PETN sample has no sign of decomposition.

Thanks for the information both of you. My ETN was twice recrystallized as well (with acetone). Sounds like it is either difficult to get all the acid
out or I am not doing something totally correct. Hopefully I can get that sorted out.

TACP Crystals Slow to Develop
I'm following the synthesis method presented in your video for the preparation of TACP (later to be converted to CHP). I'm using 12.4 g of 1.2 mm
diameter pure copper wire, 103.3 g 25% Ammonium Hydroxide (aq), and 31 g Ammonium Perchlorate placed in a large Mason jar with a 5/8" hole in the
center of the lid.
I fabricated a foam/wood base so I could place the jar in my lathe. I've been running the lathe for about 5 min every 20 - 25 min at 120 rpm. I
started at 1100 hrs and it is now 1600 hrs. Vibrant blue crystals have formed in the Mason jar but the yield appears to be pretty low. Just looking
at the crystals in the jar, I'd guess about 2-3 g. The crystals are relatively small; like coarse sand. Ambient temperature is on the high side of
the 20 C to 25 C range. Photos of the jar mounted in the lathe are below.
I think my process is working but it is very slow. Any ideas on what I should be doing to speed up the reaction and crystal development.

AFAIK, low (40-50C) heat wont destroy the complex, as long as its relatively airtight. And setting the vessel on a stirrer instead of a lathe shouldnt
really affect yields. It is better to complex all of the solid Cu first, then chill to yield the crystals you want.
Also, do you want large crystals or small ones? If you want to use the TACP to make CHP, then crystal shape/size shouldn't matter anyways.

TACP Synthesis Reaction Rate
Ultimately, this TACP will be processed into CHP so crystal size doesn't matter for my application. I was just noting that I'm getting pretty small
crystal size.
My understanding of the process requirements, per LL postings and video, is that a moderate amount of free O2 is required for the metallic copper to
react with the ammonium hydroxide in solution. This is why there is a hole in the center of the lid. After about 14 hrs of with spinning the lathe
for 5 min every 20 - 30 min, I ended up with about 8 g of TACP of vibrant medium blue color. There was a lot of unreacted copper metal remaining.
I should have weighed the copper wire to see how much was reacted but didn't think of it at the time. The wire I used may have been a larger diameter
(smaller surface area) than LL used in his video. I've got some smaller gauge wire that I'll try in the next synthesis.
