摘要
采用毛细管气相色谱/质谱/色谱保留指数联合解析技术,研究了煤焦油精制软沥青炭化馏出物的化学组成,从中鉴别出110种化合物;采用精馏法对煤焦油精制软沥青炭化馏出物进行分离,轻油（小于170℃）、酚油（170-210℃）、萘油（210-230℃）、洗油（230-300℃）、蒽油（300-360℃）。为煤焦油精制软沥青炭化馏出物的集中加工和新产品开发提供了重要实验依据。
Composition for carbonized distillate of coal - tar refined soft pitch was studied by capillary gas phase chromatography - mass spectroscopy and retention index combined analytic technology, and 110 kinds of compounds were identified. Five fractions were obtained by rectification from carbonized distillate of coal - tar refined soft pitch and identified. Result showed that the fractions obtained between 135 - 170℃, 170 - 210℃, 210 -230℃, 230 -300℃ and 300 - 360℃ were light, phenol, naphthalene, wash and anthracene oil respectively. The method provided data for the central processing of carbonized distillate of coal - tar refined soft pitch and new preduet development.
