Long term storage of TACP

mysteriusbhoice - 20-7-2020 at 05:29

so I produced some TACP using membrane electrolysis of NaClO4 using copper anode then subsequent ammoniating the basic perchlorate insoluble precipitate then decanting and filtering of produce I got this.
video of burning test.

I want to know if its safe to store TACP long term under room temp condition or is there risk of fire or explosion otherwise imma just convert it into AP.

edit:
if requested I can make a full video on the process of making TACP using my membrane electrolysis + ammoniation method.

Probably safe in a plastic container + ziploc bags. How long term are you talking? Wiki says it will completely decompose after 6 months of storage.

IDK what to really do with this so I plan to just keep it as a suveneir but also perhaps if I store it in an ammonia atmosphere in an airtight container then it might not decompose.
I only made it using my alternate method which im still improving.

I guess I don't have to tell you that storing this material is always a bad idea, especially for longer periods.
Under water/alcohol in the freezer is likely to cause the least decomposition.

Id like to see a video!

It is safe to store the ammine complex of copper(II) perchlorate. I made this complex myself (and I also made the nickel complex) and stored it for months. I even ampouled some of the crystalline material, making a nice demonstration ampoule wih dark blue crystals. I have this ampoule for a year or so and it still is in perfect condition.
I did the same with the tris (en) complexes of copper perchlorate, nickel perchlorate, cobalt perchlorate and zinc perchlorate. These also store perfectly well and are safe on long-term storage.
The hydrazine complex, however, of these metal perchlorates is not safe. It may explode unexpectedly!

If I remember correctly, Dr Liptakov once wrote that his system Berta with TACP wont work after some month of storage.

There must be some kind of decomposition.

I stored TACP, dry, without ammonia smell, in polyethylene zip bags, since 2019 (3 years now) without any signs of degradation.

I really don't know why keep this substance with ammonia traces.

Probably it can sensitize the mixture for detonator use, but it is a bad idea to keep it like this (and use in detonator anyway, it don't works for me when dry...)

In system Berta, when are both end open, only pressed, can be expiration only 3 months. For reliable DDT. But in hermetic metal cavity is storage without restrict. In amateur practice, detonators are not produced for storage. They are usually only tested within a few hours of production.
For other properties, what Woelen wrote applies.
