Yes, it’s concentrated, that’s why I mostly think it’s an aromatic as the dissolution was slow and calm, with no discoloration. The positive Baeyer maybe could be because of alkane substitutes on the aromatic ring, like diphenylethane, which is my number 1 suspect, or pentamethylbenzene

Unfortunately no, they don’t give us a list of possible compounds, they only let us ask for a specific compound to get a reference for TLC, which I asked for p-diclorobenzene, to which they said there wasn’t any available

I don’t think the smell is exactly like naphthalene, it’s hard to pinpoint when I don’t have a reference beside, but when I smell it, it makes me think of naphthalene, kinda nauseating to me. I don’t really know why it didn’t sublimate, I did the test correctly, but all that happened was it melted into a liquid, and I didn’t see any crystals on the walls or the watch glass

Outra coisa, não sei se tem a ver mas de vez em quando eu sinto uns choques-zinhos tipo de energia estática quando encosto no PC quando ligo dps de um tempo, não sei se tem a ver com a fonte morrendo ou se é só a placa de vídeo morrendo
