DDNP Synthesis

[stanfield]

Now, this is the third time I try to make DDNP following exactly the megalomania's synthesis...
I obtain a yellow powder instead of a "dark brown color" and, when I struck down this powder, it doesn't detonate. Megalomania said "but it will only burn RAPIDLY if ignited in the open, even several grams" So, I ignited some of my powder, it burnt but very slowy !!!

what are the possibly causes of mistakes during the manufacture of DDNP ?

(I'm sure I produced very good quality picramic acid from my industrial picric acid, he is red like mentioned...)

Any reply is more than appreciated !

The colour of DDNP can vary, depending on crystal size and form, and probably a few other things. IIRC it varies from dark brown to lemon yellow, the yellow form normally being produced by recrystalisation from a solvent.
If you had pure picramic acid, and pure NaNO2/KNO2, then I can't see how anything could have gone wrong, since there obviously has been a reaction.
I don't mean to sound patronising, but are you *sure* it's totally dry?
