NOVELTY - Preparing nitro compounds by solid acid nitration of aromatic hydrocarbon compounds involves nitration reaction of aromatic hydrocarbon compounds and carrying out nitric acid in a tubular reactor filled with solid acid catalyst, and subjecting the nitration reaction product to alkali washing, water washing and refining to obtain nitro compounds. USE - Method for preparing nitro compounds by solid acid nitration of aromatic hydrocarbon compounds. ADVANTAGE - The method is simple, realize continuous stable production of aromatic compound. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of a nitration reaction tube reactor.
