Abstract:
The activity and the selectivity of zeolites H-M-ZSM-5, where M=Al, B, Fe, Ti, ZSM-12 and β-zeolites in nitration of benzene, toluene, ortho-, meta- and para-xylenes, mesitylene and chlorobenzene at 25-250°, have been studied. The compn. of products is similar to that obtained in liq. phase nitration. N2O4, which forms H-complexes with the bridge OH-groups of zeolites, was a predominant species of the nitrating agent on the surface. The complexes are in equil. with nitronium ions, the concn. of the latter being negligibly low. A mechanism of nitration on the zeolite surface was proposed. The reaction of nitration was complicated by the competitive adsorption of substrate mols. and nitro compd. on the active sites of a catalyst.
