Abstract: Continuous preparation of pyromellitic dianhydride (PMDA) from durene has been studied using a fixed-bed reactor. The reaction was performed using a phosphorus-vanadium-titanium ternary catalyst. Relatively high selectivity and yield of PMDA was obtained. The in-situ characterization was combined with theoretical calculation to reveal the reaction mechanisms, and the remarkable doping effect was discussed.

Key words: Continuous oxidation, Anhydride, C-H activation, V-Ti-P ternary catalyst
