Synthesis of MIL-53 (Fe) metal organic framework materials catalyzing application of C-O oxidation reaction in organic synthesis

Abstract

    MIL-53 (Fe) includes Fe metal clusters interlinked through multi-functional organic bonds to create a 3-dimensional porous network, with large empty volume and large surface area. MIL-53 (Fe) is synthesized from iron (III) chloride and terephthalic acid (H2BDC) in the presence of DMF solvent at high temperature, MIL-53 (Fe) has an octahedral structure and its surface area (BET) can be up to 4000m²/g, hole size is about 0.85 nm. Therefore, MOFs are widely used in many fields such as catalysis, adsorption and storage of gases and medicine. In this experiment, MOFs (Fe-MOF) are used as catalysts in the synthesis of 1,4-dioxan-2-yl benzoate from benzoic acid and 1,4-dioxane with 70% efficiency.
