摘要：

HY molecular sieves were dealuminized with nitric acid of different concentrations. The dealuminized HY molecular sieves had different specific surface areas and pore sizes. The Sn-doped bifunctional catalyst for the conversion of glucose to 5-HMF was prepared by impregnation method using the dealuminized molecular sieve as the carrier. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption/desorption, X-ray photoelectron spectroscopy (XPS) and acid-base titration. The results showed that the synthesized 0.5mol/L-10% Sn-HY had mesoporous structure, octahedral morphology and suitable B/L acid site ratio. In the reaction system of methyl isobutyl ketone (MIBK) and NaCl-H2O, the yield of 5-hydroxymethylfurfural was 67.3% under the optimized conditions of 0.2g catalyst, 165℃ and 60min. After five cycles, the 5-HMF yield could still reach 49%, indicating that the catalyst had good stability. Meanwhile, the reaction mechanism for the conversion of glucose to 5-HMF was preliminarily investigated. Overall, this work established an efficient multiphase catalytic system that demonstrated the great potential of converting biomass into platform compounds. © 2024 Chemical Industry Press Co., Ltd..
