| Abstract: | High temperature coal tar was used as raw materials, it was distilled to 280℃ for getting coal tar soft pitch, and then a refined soft pitch was obtained by solvent extracting and subsequent settlement method. Its group compositions were obtained using Suoshi extracting method. The distribution and heat stability of nitrogen in coal tar refined soft pitch were discussed by element analysis, and unstable nitrogen was analyzed by IR. |
