Hydrazine Picrate Synthesis?


I heard on another thread that Hydrazine Picrate is possible. If so could it be synthesized from Hydrazine Sulfate and not Pure Hydrazine?

I really have no idea.

Seems to me this compound is rather useless. I am not even sure it is any less sensitive or more powerful than plain picric acid.
Ammonium Picrate might be useful for sensitizing NH4NO3, or possibly some fusion between picric and hydrazinium nitrate. Hydrazinium nitrate (the mono-nitrate) has a melting point around 63 °C. A small amount of picric acid would probably dissolve into such a melt, then it could be allowed to cool to form a solid mix. This would likely be very hazardous, of course. If you do try it, be sure to use a hot water bath to melt it, NOT direct heating.

Why do you always think about exotic shit, which hardly can be prepared? It is typical childish behavior. Make picric acid and its salts- ammonium and kalium ones. There is no way to leap over simple things directly to complicate procedures. Time to grow up.

Exactly. We hardly have any idea what happens in our reactions really. We have no idea what isomers of the TNP are given and how much lower nitrates are made. How does the product behave in storage. What happens in contact with copper and aluminium. How can the acidity interact with other compounds like RDX or AP. It would be great to have a maximum density melt of 20% TNP 80% RDX wouldn't it? Like overpowered composition B. I'm currently making tests on the storage under extreme conditions on some compounds.

If you're not interested with exotics, then don't click on threads that are specifically titled with them.

Title it "Hydrazine Picrate - Exotic EM" or something to that effect. Then you should avoid the hate, otherwise, they're in the wrong.

It would be great if somebody makes an exotic and posts video of tests and reports stability and possible issues.

Well hydrazine picrate. Here there, but with picric acid instead of sulfuric. Somebody confirm this?

So pretty much that makes Hydrazine in situ before being neutralized with Sulfuric Acid?

Oh shit sorry! Dont do what I told you to. I was very wrong. Hydrazine in any form in an apartment is probably a bad idea.

Maybe if you can find a better place? TNP is not so bad, but HNO3 in an apartment is an accident waiting to happen.

I do not see how that would be any more difficult to prepare than hydrazine picrate. Preparing hydrazinium nitrate from a hydrazine salt would not be any more difficult than making hydrazine picrate. And either way, you need picric acid.

Why do you say it would be "exotic" ?


Ever heard of freebasing?

Another route might be to try calcium picrate with hydrazine sulfate, though that might not be very successful since hydrazine sulfate has a rather low solubility, a repeated fractional crystallization may not be very practical. (CaSO4 is insoluble, so precipitates out of the solution, if you did not know that you should not be messing with hydrazine)

Exotic here means, that this compound is useless and has no advantages, compared with simple ammonium picrate.

how so..? as in actual HNO3 spill or NOx fumes?




~25 drops = 1mL @dH2O viscocity - STP
Truth is ever growing - but without context theres barely any such.

I think he meant N2H4, not HNO3.

Sorry for being so vague, here:

I meant N2H4. With a mistake it could cause poisoning of everybody! Hydrazine poisoning is not very nice... and easy to come by from the vapor.

BTW, once I made small amount of calcium picrate. I do not sure, that this compound is soluble in water, so it hardly could be used for synthesis of another salts. I'm not sure, because I made all salts (except lead one), mixing slurry of picric acid with small amount of water and corresponding carbonate (natrium, kalium, ammonium and so on). Small excess of carbonate is useful, because it guarantees neutral reaction. Free acid usually is not welcome. Well, I burned calcium salt and did not found something really remarkable compared with kalium one.

Just what I said. I had a slurry of picric acid and some water. I added CaCO3 in small portions, mixing it with a plastic spoon. When evolution of CO2 has stopped, I dried obtained product. As you may see, I had no way to get to know if calcium picrate is soluble. I do not see, why there are recommendations to dissolve picric acid in water and neutralize it with ammonia (or another base). BS. Small amount of water, added to aforementioned acid, makes it able to react with carbonates (dry acid does not react or reacts very slowly). Evolution of CO2 indicates if free acid presents or already not.
