The gas-phase reaction of biphenyl oxidation with nitrous oxide on iron-containing zeolite MFI was studied. It was shown that the main products of this reaction were monosubstituted phenylphenols, which were represented predominantly by para- and meta-isomers. Optimal reaction conditions, ensuring a high selectivity for phenylphenols (similar to95%), were found. The initial catalyst productivity was similar to1.5 mmol of PhPhOH/(g h). The activity decreased in the course of the reaction as a result of catalyst deactivation by coking.
