摘要

以低温煤焦油沥青为原料,依据四组分分析法,将其分为饱和分(Sa)、芳香分(Ar)、胶质(Re)和沥青质(As)。基于X射线光电子能谱(XPS)、核磁共振(NMR)、傅立叶变换红外吸收光谱(FT-IR)、元素分析(EA)、相对分子质量(GPC)及紫外(UV)等分析结果,采用改进的Brown-Ladner法计算各组分的结构参数。结果表明:就分子量而言,As(5008)>Re(1042)>Sa(771)>Ar(602);Sa、Ar、Re和As中C
Abstract

Using low-temperature Coal tar pitch as raw material, it was divided into saturates (Sa), aromatics (Ar), resins (Re) and as⁃phaltenes (As) according to four-component analysis. Their compositions and structures were analyzed by X-ray photoelectron spectrome⁃ter (XPS), nuclear magnetic resonance(NMR), Fourier transform infrared spectrometer (FT-IR), elemental analyzer (EA), gel per⁃meation chromatography (GPC) and UV-fluorescence spectrometer (UV) analyzer. The improved Brown-Ladner method was used to cal⁃culate the structural parameters of each component. The results show that the molecular weight of components follows the order of As(5 008) > Re (1 042) > Sa (771) > Ar (602). The relative content of C
