摘要
以高温煤焦油为原料,经蒸馏、溶剂萃取沉降以制得煤焦油精制软沥青,再经溶剂索氏提取制备族组成;通过元素分析来研究杂原子氮的分布和热稳定性,通过红外光谱(IR)鉴别不稳定性氮基团的结构。
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.
