Abstract

The structure of coal tar pitch produced from industrial tar and pitch produced from tar modified by ozone is compared. The pitch structure is identified by standard analysis of pitch, IR and NMR spectroscopy, and elemental and thermogravimetric analysis. Modification of tar by ozone increases the yield of pitch, its content of the α fraction, the yield of volatiles, and the softening temperature.

煤焦油臭氧处理对沥青质量的影响

比较了由工业焦油生产的煤焦油沥青和由经臭氧改性的焦油生产的沥青的结构。通过沥青的标准分析、红外光谱和核磁共振光谱以及元素分析和热重分析，确定了沥青的结构。用臭氧对焦油进行改性可提高沥青的产量、α 部分的含量、挥发物的产量和软化温度。
