能源化学工程专业学生创新实验—中低温煤焦油沥青的结构分析

Energy Chemical Engineering Students Innovative Experiments—Structural Analysis of Low-Temperature Coal Tar Pitch

以中低温煤焦油沥青为原料,选择四种不同极性的溶剂开展分级萃取实验,得到四级萃取物和四级萃余物。根据热重和傅里叶红外光谱测试结果,使用Origin绘图软件作图,初步探讨了各组分的结构特征。该实验较为系统,适合作为本科生的专业实验。

The medium-low temperature coal tar pitch was used as the raw material, and was extracted by four kinds of solvents with different polarities to obtain four extracts and four residues. According to the results of the thermogravimentric analyzer and Fourier infrared spectroscopy test, qualified figure was obtained by Origin software, and then the structural characteristics of each product was discussed. This experiment involves a systematical process, and thus is suitable to be carried out as a specialized experiment for Energy Chemical Engineering specialty.
