Hi all,

I need to prepare some solutions of picrate salts. Typically, nitrate salts are mixed with a solution of picric acid to prepare a solution of the picrate salt. I've also seen a few examples where carbonate salts are used instead of nitrates. Does anyone out there know if it's possible to use perchlorate salts for the same purpose (ie prepare the picrate salts by adding perchlorate salts to a solution of picric acid???)

Cheers!

Look up the properties of these compounds before you do anything. They are rather energetic species. Then rethink the whole thing.

Yup, read the title as Pirate Salts...

Metal picrates?

Imma have to second Disco on this one. Unless you know exactly what you are doing, there's a very good chance you could cause an explosion.

I recon an admin should lock this thread.

I am making solutions of picrate salts for the Pedersen extraction technique - it's a very widely used technique to determine metal ion selectivity!!! I will, in fact, be preparing low molarity solutions of the metal picrates and will not be handling them neat.

Some of the metal perchlorates are of low solubility, and should you want to prepare the picrate salt pure, and not in solution, looking at the solubility of each will be very important.  Personally I would use the carbonates as you have no other ions in solution after loss of carbonate as CO2 and H2O.  But since it appears you only need an aqueous solution of the picrate, starting with nitrate, carbonate, perchlorate, will all work.  

I have posted impact sensitivities for picrate salts in another thread, and for the most part they are overrated.  Exception: lead, silver, mercury, thallium, but we are still talking hammer hit to set off, not spontaneous explosions.

Bottom line is: Discussion of the synthesis of explosives is not allowed.

I know might be a borderline case with legitimate motives, but the drugs/explosives rule is our biggest, strictest rule. There can be no exceptions, even if it does stop legitimate chemistry discussion from time to time.

poorstudent83, Investigate safer alternatives first. DO NOT perform these experiments without the supervision of an experienced chemist, and make sure all appropriate safety precautions are taken.
