对贾汪镜煤质低度氢化产品中石油醚可溶分的<200℃和200—320℃各液体色谱段分进行了气液色谱鉴定,鉴定出10个C_9—C_(18)正构烷烃,估计还存在有9个C_(10)—C_(18)的2-甲基长链烷烃。和标准样品进行对照,还对出了相当于顺式十氢萘、反式十氢萘、甲苯、乙苯(二甲苯)、正丁苯、四氢萘、萘、甲基萘、二甲萘、苊、联苯和芴等12个峯. 对<200℃的芳烃段分和200—320℃的双苯核芳烃段分的气液色谱图进行峯的适当合并后,就可以基本上按碳数与环数和来进行族分析,碳数与环数和相同的化合物可归并在一个族内.<200℃芳烃段分可以区分为甲苯、乙苯、丙苯、丁苯(茚满)、四氢萘、甲基四氢萘、乙基四氢萘、丙基四氢萘和丁基四氢萘等9个族;200—320℃双苯核芳烃段分可以分为萘、甲基萘、二甲萘、苊(丙萘)和芴五个族. 由低度氢化产品中存在有高碳数的石蜡族化合物,可以推测在镜煤质主体结构中存在有高碳数的石蜡族侧链.其来源可能是富含蜡和脂肪的树皮、角质、花粉、孢子以及低等植物如藻类等.
The liquid chromatographic identification of various liquid chromatographic fractions of <200 ℃ and 200-320 ℃ for petroleum ether-soluble fraction of low-grade hydrogenated products of Jiawang Jing was carried out, and 10 C9-C18 n-alkanes were identified. There are 9 C_ (10) -C_ (18) 2-methyl long chain alkanes. In comparison with the standard samples, we also obtained the equivalent of cis-decalin, trans-decalin, toluene, ethylbenzene (xylene), n-butylbenzene, tetrahydronaphthalene, naphthalene, methylnaphthalene, , Acenaphthene, biphenyl and fluorene, etc. The appropriate combination of peaks for gas-liquid chromatograms of aromatic fractions <200 ° C and dibenzophthalic aromatic fractions of 200-320 ° C can be carried out on carbon Number and ring number and for family analysis, the number of carbons and the number of rings and the same compound can be combined within a family <200 ℃ aromatic fraction can be divided into toluene, ethylbenzene, propylbenzene, butylbenzene (indane) Tetralin, methyltetrahydronaphthalene, ethyl tetralin, propyl tetralin and butyl tetrahydronaphthalene and other nine families; 200-320 ℃ disintegrant bisbenzene aromatics can be divided into naphthalene, methylnaphthalene , Dimethylnaphthalene, acenaphthene (propanenaphthalene) and fluorene five groups from the low degree of hydrogenation products exist in the high paraffin wax compounds, it can be speculated in the main structure of the mirror coal quality there is a high carbon paraffin side The source may be wax and fat-rich bark, cutin, pollen, spores and lower plants such as algae and the like.
