摘　　要：经过酯交换、水解两步反应制备了有机配体1,3-二乙酸咪唑。利用溶剂热法以硝酸锌为金属源制备了金属-有机框架材料Zn(C7H7N2O4)2,并对其进行了温度优化、时间优化以及反应物比例优化,采用了X射线衍射(XRD)对其进行了表征分析。同时采用以苯并噻吩为模型化合物,在相同条件下进行吸附脱硫效果评价。实验结果表明:M-2/T-120/t-72显示出最佳的吸附脱硫性能。After reaction by the two steps of ester exchange and hydrolysis,organic ligand 1,3-two acetic acid imidazole was prepared.Then Zn（C7H7N2O4）2 was prepared by a solvothermal method used zinc nitrate as the source of the metal.At last making a series optimization of temperature,time and proportion,and properties of the results products were characterized with XRD.At the same time using benzothiophene as a model compound and under the same conditions,the adsorption desulfurization effect was evaluated.The result showed that M-2/T-120/t-72 demonstrated the best catalytic performance in the adsorptive desulfurization reaction.
