神华煤钌离子催化氧化解聚产物的FT-ICR MS分析研究

针对神华长焰煤初步开展了钌离子催化氧化法(RICO)的应用研究，对原煤进行降解反应并尝试运用高分辨电喷雾傅里叶质谱仪（ESI-FTMS）对氧化产物进行分析表征。结果表明，神华煤含有C-2～C-32烷基侧链和连接芳环之间的C-2～C-27亚甲基桥链，芳环缩合程度相对较低（主要以含有2～4个苯环的共轭结构为主），有较多醚键连接的芳环结构及羟基（-OH）、羰基（CO）和甲氧基（-OCH-3）等含氧官能团存在。

FT-ICR MS analytical study on the products of Shenhua coal using Ruthenium-Ion-Catalyzed oxidation method

In this study，the authors have conducted some preliminary investigation in the ruthenium ion catalyzed oxidation (RICO) on the Shenhua long flame coal，and for the first time，used high resolution electrospray Fourier mass spectrometer (ESI FTMS) to characterize the oxidation products.The results show that the Shenhua coal contains alkyl side chains at a length of C-2-C-32 and alkyl bridge between aromatic rings at a length of C2-C-27.The aromatic condensation level is relatively low (majority of conjugated structure of 2-4 benzene rings)，and the average distance between aromatic rings is relatively large，with an overall loose structure.Abundant ether linked aromatic structure includes hydroxyl (—OH)，carbonyl (CO)，and methoxy (—OCH-3).
