| Abstract: | First,the hierarchical ZSM-5 zeolite was prepared by hydrothermal method using mesoporous template cetyltrimethylammonium bromide (CTAB). The physical and chemical properties of the hierarchical ZSM-5 zeolite were characterized by X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR) and N2 adsorption-desorption and Scanning electron microscope (SEM). Then,the as-prepared hierarchical ZSM-5 zeolite and ion exchange resin were used as catalysts to evaluate the reaction performance of the synthesis of tributyl citrate. Compared with the ion exchange resin,the as-prepared ZSM-5 has a microporous and mesoporous composite structure and a large specific surface area,so that significantly improving the catalytic performance of synthesizing tributyl citrate and increasing the esterification rate of the reaction 8.7%. |
