摘　　要：本文描述了以配位化学为知识背景,以绿色化学为核心理念的MOF-5合成及其性能测试实验。实验采用化学合成法,以二水醋酸锌为原料,在有机胺去质子化作用下与对苯二甲酸自组装得到产物。利用红外光谱分析、热重分析(TGA)、粉末X射线衍射(PXRD)表征了产物纯度、结构与稳定性,分光光度计测定了产物对常见染料的吸附性能。通过该实验的学习,学生能强化配位化学理论知识的理解,掌握大型仪器设备的使用,理解吸附原理,树立爱护环境、关爱地球的绿色发展理念。本实验反应条件温和,产率、原子利用率高,绿色无污染,教学安排节奏紧凑,非常适合作为结构化学、物理化学等课程的实验项目。This paper describes an experiment for synthesizing MOF-5 using the principles of coordination chemistry and green chemistry.Zinc acetate dihydrate was used as the starting material,and the product was self-assembled with terephthalic acid by deprotonation of the organic amine.The purity,structure,and stability of the product were characterized by infrared spectroscopy,thermogravimetric analysis(TGA),and powder X-ray diffraction(PXRD).The adsorption properties of the product with common dyes were studied by UV-Vis spectrometry.By studying and conducting this experiment,students can strengthen their understanding of coordination chemistry theory,master the use of large-scale instruments and equipment,master the adsorption principle,and gain an understanding of green chemistry regarding caring for the environment.This experiment has mild reaction conditions,high yield,stoichiometric chemistry,and green chemistry and is pollution-free.It allows for a compact teaching schedule,which is very suitable for teaching experiments in structural chemistry,physical chemistry,and other courses.
