: : : 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:

Well just in case some one just try it. I think it would be good of you to mention the conditions need to get the DNP instead of the compound that goes KABOOOOOM (just a thought) : )
