Mesophase pitch has been successfully prepared at very highly yield from aromatic hydroearbons with low contaminant levels using HF/BF_3 as a catalyst. The derived carbon fiber is expected to be of high performance and to be produced at reasonable cost. The synthesis, structure, and properties of the mesophase pitchs, which are strongly dependent upon the starting aromatic hydrocarbons and preparation conditions, will be described. The spinning process can control the shape and texture of the fiber, both of which are intimately related to performance. Fibers with a flat cross section, as thin as 1.5 micrometer, and round fibers with random texture can be produced when the spinning nozzle and the mesophase pitch are properly selected. Acceptable compression strength has been obtained with the ranbdomtexture in the round realized by slow heating during stabilization. Some other applications of mesophase pitch can be addressed.

以HF/BF_3为催化剂，以低污染的芳烃为原料，以很高的产率成功地制备了MIBase沥青。期望衍生的碳纤维具有高性能并且以合理的成本生产。中间相沥青的合成，结构和性能，这是强烈依赖于起始芳烃和制备条件，将被描述。纺丝过程可以控制纤维的形状和质地，两者都与性能密切相关。选择合适的喷丝头和中间相沥青，可纺出截面扁平、细至1.5 μ m的纤维和具有随机织构的圆形纤维。通过在稳定化过程中缓慢加热实现圆整的随机织构，获得了可接受的抗压强度。中间相沥青的一些其他应用也可以解决。
