摘要：

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 alpha fraction, the yield of volatiles, and the softening temperature.
