煤沥青的结构组成研究

Review of Research on Structure of Coal Tar Pitch

煤沥青的来源丰富、价格低廉、用途比较广泛,是制备碳素材料粘结剂、针状焦、碳纤维、中间相沥青等的优质原料,所以了解其理化性质以及热性能显得尤其重要。本文利用红外光谱图研究煤沥青的结构组成,为进一步利用煤沥青做好理论基础。

The coal tar pitch is a chemical raw material of abundant source, low price and more extensive use. It is usually used for preparing adhesive agent, needle coke, carbon fibre and mesophase pitch. Therefore the holding its physics - chemical properties has become particularly important. In this paper, the structure of coal tar pitch is studied by IR, and it supplies a theoretical foundation for further use of coal tar pitch.
