摘要
以PET饮料瓶为原料,乙二醇为溶剂与反应剂提取对苯二甲酸。并用红外光谱和核磁光谱对产物的结构进行了表征。该实验可使学生综合掌握加热回流、减压蒸馏、减压抽滤等多项基本有机实验操作技能以及熟悉分析表征手段,并构建绿色化学、保护环境的理念。
Terephthalic acid was recycled from waster PET beverage bottles using ethylene glycol as the solvent and reactant.The recycled products were characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy.In this experiment,undergraduates acquired variable basic experimental skills such as heating reflux,vacuum distillation and vacuum filtration,and were familiar with analysis and characterization methods.Thus,students′concepts of green chemistry and environmental protection were formed during the experiment.
