Abstract:

Nano/microscale copper metal-organic framework(MOF) catalysts were synthesized via hydrothermal method or precipitation and characterized by FT-IR, TG and TEM, respectively. The effects of these catalysts, solvent, and reaction time on the oxidation of isoeugenol to vanillin were investigated. Cu-BTC containing BTC(1,3,5-benzenetricarboxylate) ligand is found to exhibit the best catalytic performance. When employing Cu-BTC as catalyst, 30%(mass fraction)H2O2 as oxidant, 94.4% conversion of isoeugenol and 81.8% yield of vanillin are achieved with n(isoeugenol):n(H2O2)=1:2.4 after 8 h reaction at 50 ℃ in acetonitrile. Additionally, nano/microscale Cu-BTC(diameter ca. 30~300 nm) exhibits good reusability and ~90% conversion of isoeugenol can be maintained in 5 recycles.
