By means of such process, 0.57% of benzene conversion, 100% of phenol selectivity and 26.6% of anthraquinone-utilized efficiency were achieved upon the mixed Pd/γ-Al2O3-NH4VO3 (V/Pd molar ratio for 4) in the presence of benzene/acetic acid (4v/10v). Above all, after the coupled reaction system was recycled three times, the accumulated phenol amount could achieve ca. 0.833mmol and its average value (ca. 0.278mmol) was slightly higher than phenol amount obtained in the first run (ca. 0.255mmol), indicating that such coupled reaction system could be recycled efficiently. In addition, a synergistic mechanism was proposed to explain the favorable effect of V compound on the Pd/γ-Al2O3 catalyst.
