Efficient, continuous oxidation of durene to pyromellitic dianhydride mediated by a V-Ti-P ternary catalyst: The remarkable doping effect

A new synthetic method: pyromellitic dianhydride preparation by Ni–Mo/ZrO2 catalytic oxidation

“…However, the cost of the catalyst was high and no mention was made of the catalyst recycling ability, which makes it unsuitable for industrial production. 13 To address the aforementioned issues, we have devised a novel preparation method for PMDA, emphasizing simplicity, ease of use, affordability, and high selectivity and conversion rates.…”
