Title: A simple synthetic process for the nitration of aromatic compounds


Invention: The University of Arizona presents a novel, one-step, catalyst-free, and solvent-free synthetic process for the nitration of aromatic compounds. This method has been used to prepare 2,4-dinitroanisole, an alternative to trinitrotoluene (TNT), as an ingredient in melt-cast explosive formulations; and dinitrophenyl ethers. This synthetic process can be utilized to produce a variety of nitroaromatic compounds in a fast, straightforward, and more economical fashion than traditional chemical methods.


Background: Traditional synthetic nitration methods often employ catalysts, solvents, or other additives that are harmful to the environment and/or expensive. This synthetic process overcomes these issues by allowing the nitration of various aromatic compounds in a catalyst-free and solvent-free fashion.
