英文摘要: Abstract(#br)The composition and structure analysis of coal tar is a very important basic issue. In the process of preparing asphaltenes (insoluble in C5-C7 n -alkanes but soluble in hot benzene, HIBS) according to the definition, it was found that hot benzene insoluble (HIBI) components still exist in the coal tar. It is necessary to carry out in-depth analysis and identification of their compositions and structures, in order to obtain detailed information, which provides a certain guiding significance for the deep processing of coal tar. Their compositions and structures were studied by means of physical and thermo-chemical analysis, including Fourier transform infrared spectroscopy (FTIR), Uv-fluorescence spectroscopy, X-ray photoelectron spectroscopy (XPS), 1 H magic angle spinning...
