| Abstract: | With purified pitch containing low QI as raw material, the hydrogenated pitch has been prepared by tetralin hydrogenation at high pressure. The hydrogenated pitch and the purified pitch are studied using IR, NMR and TGA techniques. It is found that the hydrogenated pitch contains a large amount of alicyclic structures, and has unique behaviors in thermal decomposition and condensation process, and this favors the preparation of soluble mesophase pitch. |
