用薄层色谱法对12种已知芳烃和贾汪镜煤质低度氢化所得各沸点馏分、沥青质以及经硅胶液体色谱分离后得到的各芳烃段分进行了考察.指出芳烃在氧化铝和硅胶薄层色谱上的次序主要按芳环数,尤其按双键数(包括相互共轭和不共轭的)排列,同时指出了芳烃混合物在薄层色谱上进行族分离的可能性. 指出液体色谱分离得到的单苯核芳烃段分中不会含有象联苯、二苯甲烷系类的化合物,因此液体色谱分离所得环烷和单苯核芳烃段分应该就是以这样的形式作为基本结构单元存在于煤结构中,而不是煤中其他结构单元在氢化过程中的加氢产物.
The results of thin layer chromatography on the boiling points, asphaltenes and various aromatic fractions obtained from the separation of 12 known aromatics and Jiawangjing low-hydrogenated coal were also investigated. The order of the layers on the chromatogram is mainly based on the number of aromatic rings, in particular, by the number of double bonds (including conjugated and unconjugated conjugates), and also indicates the possibility of aromatic separation of the aromatic mixture on a thin layer chromatography. The obtained monobenzene-aromatic hydrocarbon fraction does not contain compounds such as biphenyl and diphenylmethane series. Therefore, the fraction obtained by liquid chromatographic separation of naphthenic and monobenzene-aromatic hydrocarbons should exist in such a form as the basic constitutional unit Rather than the hydrogenation products of other structural units in the coal during hydrogenation.
