he components of middle oil fractions in high-temperature coal tar were investigated by gas chromatog-raphy/Fourier transform infrared-retention index method,which was developed previously by the present au-thors,combined with the relationship between retention indices and boiling points for homologous series.More than 41,53,64 and 60 compounds were separated and identified respectively in 170~210℃,210~230℃,230~270℃ and 270~ 300℃ fractions of middle oil.The quantitative and qualitativ results are com-pletely presented in the paper.

在原有研究工作基础上,采用气相色谱/傅立叶变换红外光浴保留指数(GC/FTIR-RI)技术,结合同系物保留指数与沸点的关联式中斜率因子的重要作用,研究了高温煤焦油中油馏分的化学组成。分别从F_3、F_4、F_5、F_6中分离并鉴定出41,53,64,60种化合物,获得了有价值的实验数据和结果,为煤焦油的深度加工与处理提供了重要的理论依据。
