【摘要】 在40 oC恒温水浴下用次氯酸钠用Na Cl O对两种煤液化残渣进行氧化,利用GC/MS手段分析了氧化萃余物中化合物的组成和结构特征,检测到的化合物主要包括酯、酮、酸和一些杂原子化合物。同时阐述了煤液化残渣中结构组成常用的研究分析手段,为研究煤液化残渣的性质及高附加值利用提供了有益的信息。更多还原

【Abstract】 Residues from direct liquefaction of Shenfu and Shengli coals were oxidized in sodium hypochlorite aqueous solution at 40 ℃. The oxidation extraction residues were analyzed with gas chromatography/mass spectrometry(GC/MS). The results show that the detected compounds mainly consiste of esters, ketones, acids and heteroatom-containing compounds. Meanwhile, common analytical techniques were simply summarized, which could provide feasible reference for effective separation and value-added use of the oxidation extraction residues.更多还原
