高温煤焦油组成的毛细管气相色谱／傅立叶变换红外光谱研究─—中油馏分的分析

Compositional Studies of High-Temperature Coal Tar by Capillary Gas Chromatography/Fourier Transform Infrared ───Analysis of Middle Oil Fractions

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。

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.
