Peng, Wen-Li published the artcileAccelerating Biodiesel Catalytic Production by Confined Activation of Methanol over High-Concentration Ionic Liquid-Grafted UiO-66 Solid Superacids, Name: Methyl docosanoate, the main research area is biodiesel production catalyst metal organic framework ionic liquid; crystalline microporous ordered solid superacid methanol heterogeneous transesterification.
Solid acids usually show lower catalytic activities than liquid acids because of their limited acid strength and presence of obvious diffusion limitation in the reactions. We report herein a variety of ionic liquid-grafted UiO-66 solid superacids synthesized from quaternization of UiO-66 with 1,3-propane sultone, ion-exchanging with H2SO4 or HSO3CF3. The developed UiO-66 solid superacids are highly efficient in catalyzing biodiesel production toward transesterification, which were better than the ionic liquid and neat H2SO4. The remarkable activities found in the UiO-66 solid superacids benefit from the synergistic effect of high acid concentrations (~3.33 mmol/g), superacidity (determined by 31P solid-state NMR, Hammett indicators, and potentiometric titration), as well as unique shape-selective confinement for methanol into the ordered and uniform micropores, which targeted the activation of methanol to prevent the occurring of an inverse reaction in the reactions. The UiO-66 solid superacids show important application potentials in the area of biodiesel production in the industry.
