摘　　要：镜煤抽提物及残煤的ＦＴＩＲ－ＰＡＳ研究周安宁，陈邦杰，王祖侗（大连理工大学化工学院，大连１１６０２）（中国科学院山西煤炭化学研究所，太原０３０００１）关键词　ＦＴＩＲ－ＰＡＳ分析，镜煤，煤结构，喹啉抽提神木煤为不粘煤，柳林煤是主焦煤，在文献￣［３］中...The paper investigates the structure of quinoline-soluble and chloroform-iu-soluble fraction(LFI),and quinoline-insoluble fraction(QI) of Shenmu and Liulin vit-rinites preheated at 626K by FTIR-PAS technique.It is shown that FTIR-PAS techniqueis the most sensitive tool for probing complex hydrogen bond structure and quanitative analy-sis of coal structure comparing with tranditional FTIR technique,The QI and LFI fractionsof Shenmu vitrinite have higher content of OH and ether group than those of Liulin vitrinite,so that there is complex hydrogen bond structure in QI and LFI fractions of Shenmu coal.The aliphatic chain subtituent of Liulin vitrinite is shorter,and its aromaticity is higher.
