| abstract | TITLE PROCESS FOR THE MONONITRATION OF ORTHO-XYLENE ABSTRACT OF THE DISCLOSURE There is provided a process for mononitrating ortho-xylene by reacting o-xylene with catalytic amounts of nitrogen tetroxide (N2O4) or nitrogen dioxide (NO2) and concentrated nitric acid in concentrations of at least 68% in the presence of a mercuric salt and an aliphatic mono-carboxylic acid anhydride to obtain good yields of mono-nitrated o-xylene having an isomer distribution of at least a 70:30 ratio of 4- to 3- nitro-o-xylenes. Such 4- nitro-o-xylene, upon separation from the isomeric mixture, finds utility in the preparation of xylidine derived preemergence herbicides. |
