Calcium picrate.
Yesterday,I tried to make some Calcium picrate.
First,I took about 25ml of water and a little CaC2 and let it react(outside).As you probably all know,there will form ethyleen and Ca(OH)2.So after
the reaction was completed,I started adding about +-0.9 gram PA.De solution turned orange/red.Then I filtrated the solution,because the stuff on the
bottom would burn(so this is probably most Ca(OH)2,sou filtrate the solution after the reaction with CaC2 and water).Then I heated the red solution
till almost the 1/2 of the original volume.I let it crystalize out(0-5°C).Red/orange crystals were precipated.They react violently with flame with a
little crackling sound.
Could it be this is Calcium picrate then??If so,does anyone have more info about this?

Well, due to the fact you had a base, an acid, and a crystalizing component that is not Picric acid, I would say it is pretty safe to say you have
indeec prepared calcium picrate.

Dont you mean ethyne or acetylene was produced?

They are both the same thing Saerynide.  And yes ethyne or acetylene is given off by the reaction of calcium carbide with water.
Theory guides, experiment decides.

It seems like he first let the acetylene bubble of , and then used the formed Ca(OH)2.

Ca(OH)2 doesn't burn.

Yeah, I know they are the same, but (s)he said "ethyleen" as opposed to ethyne or acetylene
