1·After oxidative polymerization of pith, its volatile matter is decreased from 52.22% to 16%, and its toluene insoluble matter is increased from 30% to 81%.
煤沥青经氧化聚合后，挥发分由52.22%下降到16%以下，相应的甲苯不溶物含量由30%增加到81%以上。
2·It has no insoluble matter separated out in storing for long term and no jamming in nozzle, and it may be used to print clear and homogeneous text and graph and without fading in water.
该墨水长期存放后，没有不溶物出现，不堵塞喷嘴，经三年试用，打印的文字、图像均匀、清晰，且遇水不褪色。
3·Pitches extracted -with supercritical toluene (SCFE pitch) contained none of the quinoline insoluble (QI) matter responsible for anisotropic structures with small unit sizes.
经超临界甲苯萃取过的沥青(SCFE沥青)丝毫不含导致小单元尺寸各向异性结构的喹啉不溶物(QI)。
