Abstract

original image

Best director: The direct synthesis of phenol from benzene and O2 was performed with 78–94 % selectivity on Pt/β and Pt-Re/ZSM-5 catalysts, regulated by NH3 (see figure, (1)). An alternating process (see figure, (2)-1 and (2)-2) afforded the selective synthesis of phenol with 83–99.8 % selectivity, whilst minimizing the consumption of NH3.
