摘 要: | 对锡林浩特褐煤进行钌离子催化氧化,氧化产物经重氮甲烷酯化后用GC/MS进行分析,并由此推测原煤的组成结构。结果表明,锡林浩特褐煤钌离子催化氧化产物的主要成份是二元烷酸和苯多酸,由此推测锡林浩特褐煤中含有大量的α,ω-二芳基烷烃和稠环芳烃结构,α,ω-二芳基烷烃的烷基桥链碳原子数分布为C2~C11;苯多酸中苯四甲酸的收率最高,苯五甲酸和苯六甲酸的收率较低,表明锡林浩特褐煤中稠环芳烃结构的缩合程度较低。

Abstract: | Xilinhaote lignite was subjected to ruthenium ion catalyzed oxidation.After esterification with diazomethane,the products were analyzed with GC/MS.The results show that the main components in the products from Xilinhaote lignite are dimethyl alkanedioates and polymethyl benzenepolyoates,indicating that Xilinhaote lignite contains large amount of α,ω-diarylalkanes with carbon number of methylene linkage from 2 to 4 and relatively large aromatic clusters with three or more rings. |
