: : Someone posted a message a few days ago (it's lost now) asking for DNP synthesis information. As self-proclaimed local archivist/researcher, I happened to have an article on it in my files:

I don't know the mechanism but there is a reaction called oxynitration where an aromatic
compound reacts with mercuric nitrate and concentrated nitric acid and the product
contains both hydroxy and nitro groups. In the case of benzene the products are 2,4 DNP or
2,4,6-TNP (picric acid, KABOOM!!)depending on the reaction conditions.
