Abstract High temperature coal tar was used as raw materials, and was distilled to 280 ℃ for getting coal tar soft pitch. Then refined soft pitch was obtained by solvent extracting and subsequent settlement method. Its soft point was 32 ℃; the group compositions consisted of 53.67% heptane soluble, 39.47% heptane insoluble but toluene soluble, 6.86% toluene insoluble and 0.06% quinoline insoluble. The relative average molecular weight was about 292. Its average molecular formula was C22.22H16.32N0.12S0.06O0.33; the total content of heteroatom was less than 1. IR analytic results showed that its heteroatom O existed in the R—O—R and Ar—O—R structure; its heteroatom N existed in the R—NH—R and N, with the latter being primary. Its average structure was obtained by improved Brown-Lander model: five-membered condensed rings. UV analysis indicated that the majority was linear arrangement, and the minority was surface arrangement; namely, the chemical structure of the samples was mainly the cata-condensed structure, while the minority was peri-condensation.
