| Abstract: | The conversion rules of coal tar pitch components during the thermal polymeri zation modification were investigated in a reaction still. The results indicated that the conversions of toluene insoluble and quinoline insoluble components in coal tar pitch during heat polymerization have some laws. Its instruction meaning in the coal tar pitch production has been pointed out. |
