Abstract:
Aromatic compounds such as o-xylene are selectively nitrated by nitric acid in the presence of polyphosphoric acid and a large pore, acidic zeolite or a large pore, hydrophobic molecular sieve. This is an environmentally friendly, commercially viable, high conversion process for the selective nitration of aromatic compounds in the para position.
