2种煤液化残渣氧化萃余物中杂原子化合物的鉴定
Heteroatom-containing Compounds Identified in Two Coal Liquefaction Residues by Oxidation Extraction
【摘要】 在40℃恒温水浴下用次氯酸钠对2种煤液化残渣进行氧化,将反应所得混合物用滤膜过滤,滤出液依次用石油醚、二硫化碳、四氯化碳和乙酸乙酯萃取,得到的萃取物用气相色谱/质谱(GC/MS)分析.根据分析结果系统地考察了2种煤液化残渣中所含杂原子化合物的分布,为从煤液化残渣中选择性地脱除这些杂原子化合物及提取高附加值化学品提供了一条路径.
【Abstract】 Residues from direct liquefaction of Shenfu and Shengli coals were oxidatively deploy-merized in a sodium hypochlorite aqueous solution at 40℃.Each reaction mixture was filtrated through a membrane filter and the filtrate was sequentially extracted with petroleum ether,carbon disulfide,carbon tetrachlorite and ethyl acetate.The extracts were analyzed with GC/MS.The heteroatom-containing compounds of residues were examined according to the analytical results.This work provides an approach to remove the heteroatomcontaining compounds and conversion of coal liquefaction residues to chemicals.
【Key words】 coal liquefaction residue; heteroatom-containing compound; GC/MS; identification;
