Everything You Need To Know To Find The Best 5-Aminotetrazole Monohydrate

5-ATZ (5-Aminotetrazole), the Nitrotetrazolate Ion and More

For those who have checked the prices on Alibaba, it's evident that sourcing 5-Aminotetrazole can be tricky. The 7.5g of produced material could be converted into a nitrotetrazolate primary explosive, but if there's a secondary explosive in mind, the yield might not suffice.

Verifying Calculations

Could someone please verify my calculations stated in previous posts? I want to ensure I am not wasting precious chemicals in this experimentation process. Engager indicated 0. mol of NaNTZ. Considering the molar weight of NaCN5O2*2H2O is 173.06 g/mol, 0. mol times 173.06 g/mol equates to approximately 1.192g. The molar ratio for the copper complex to sodium nitrotetrazolate stands at 2:1, which raises questions about its practicality. However, following Engager’s guidelines may be best.

Comparative Calculations

Similarly, I calculated 3.5 grams of carbonato triammine copper(II) nitrate for every 1.91 grams of NANTZ. In contrast, with BNCP, the ratio flips to 1.4 grams of cobalt compounds for every 2.6 grams of NANTZ. As NANTZ production proves more challenging, pursuing the copper compound might be a more favorable option since it requires significantly less NANTZ.

Experiments with Primers

I've successfully synthesized BNCP and NaCUNTZ, utilizing simple primers like meal powder to detonate BNCP. However, NaCUNTZ demands a hotter primer, potentially reaching a 5/10 rating in my blasting caps. I am in search of an efficient priming composition and have experimented with an 80 lead tetroxide/20 silicon blend, which burns very quickly, reminiscent of flash powder. Recommendations for a hotter primer would be appreciated.

Experiences with Synthesis

In my synthesis, I produced a small portion of C2H4N14 bis-diazotetrazolylhydrazine, or ditetrazolylhexaazadiene. When I added nearly colorless diazotetrazole solution to hydrazinium chloride, it initially turned pink, yielding a fluffy yellow precipitate that hydrolyzed before filtration. Eventually, tiny grains of a yellow substance precipitated. Notably, even a single grain can detonate violently enough to damage aluminum foil when heated gradually. Despite this, I found it less effective as a primary explosive than I anticipated as only a few milligrams puff out when ignited; when tightly compressed, it exhibits extreme brisance. Recorded density was approximately 1.75 g/cc, in line with substances like 5-azidotetrazole. To see more, you can watch my video here: Video Link.

DBX-1

A kind contributor shared valuable insights on DBX-1. It’s mildly amusing knowing that top contributors in high-tech arenas engage in such "academic" forums. The synthesized DBX-1 I created exhibited unexpected sensitivity. Initially red, after drying it turned almost black, manifesting as small, challenging-to-powder chunks. Although these chunks were sensitive to impact, they failed to ignite upon fusing. I gave it another attempt with a different synthesis method, obtaining a more favorable yield. I’ve managed to synthesize 5-Aminotetrazole twice now. The first trial was on a small scale, blending the recipe posted by Engager. It yielded well, producing a very pure product. Recently, I scaled up the synthesis, operating with approximately 10g of Aminoguanidin bicarbonate, 200ml of 15% sulfuric acid, and plenty of sodium carbonate to manage the pH. The perplexing outcome was an impressive yield of about 100g, which seemed almost too good to be true. Upon cooling, only crystals remained, indicating to me that all impurities must have crystallized too. My final product maintained a neutral pH. For insights into the significant yield and potential techniques for removing sodium carbonates or sulfate, a recrystallization might be my best bet. A relevant video here demonstrates a similar method, yielding significant quantities.

Guidelines for Purification

It appears there's an excess of sodium sulfate hydrate. Since 5-aminotetrazole crystallizes as a monohydrate, the expectation is around 7.5g for a total 100% yield, although outcomes tend to hover around 75% with the Thiele method. Treating the product with dilute HCl may help ensure it is in the free tetrazole form – an essential step in leaching sodium salts, followed by recrystallization from water. 5-aminotetrazole is highly soluble in heated water but only very slightly soluble in cold conditions, which usually proves beneficial during recrystallization. A few reminders: always allow the filtrate to sit for several days with a few grains of the initial product while stirring occasionally, ensuring you rub the vessel walls periodically. The tendency for 5-aminotetrazole to supersaturate is notable.
