中间相沥青的制备方法研究进展

Research Progress in the Preparation of Mesophase Pitch

中间相沥青是一种具有光学各向异性的芳香类碳氢化合物的聚集体,具有液晶的特性,是重要的碳材料前驱体。原料的不同,导致制备方法具有多样性。详细阐述了国内外中间相沥青的制备方法,重点介绍了直接热缩聚法、催化缩聚法、共炭化法及溶剂萃取法制备中间相沥青,并展望了中间相沥青制备的发展方向。

Mesophase pitch is a kind of aromatic hydrocarbon aggregate with optical anisotropy,and it has the characteristics of liquid crystal and is an important carbon material precursor.The difference of raw materials leads to the diversity of preparation methods.In this paper,research progress in mesophase pitch preparation was summarized,including thermal polymerization method,catalytic polymerization method,co-pyrolysis method,and solvent extraction method.At last,the research prospect of mesophase pitch was briefly discussed.
