摘　　要：本研究为进一步分析残余煤中的有机成分,采用的是甲醇溶剂对枣庄残余煤进行了索氏萃取,并利用GC/MS/MS对萃取物的组成进行了分析.结果表明枣庄残余煤甲醇萃取物中GC/MS/MS可检测到化合物46种,其中酯类占多数,其次是脂肪烃,芳香烃占少数,含部分含氮化合物.这可推测氧化后的残余煤样中可能含有的烃类物质为芳香烃、脂肪烃,含氧化合物有醇、吡啶及醚类,还可能有胺类和芳香硝基化合物.For further analysis of organic components in the residual coa,this paper introduced that methanol solvent is used to extract by Soxhlet extraction of residual coal in Zaozhuang,and the composition of the extracts were analyzed by GC / MS / MS.The results show that 46 new compounds could be detected from Zaozhuang residual coal by GC / MS / MS,of which Esters are the majority,followed by aliphatic hydrocarbons,aromatic hydrocarbons minority,and the nitrogen- containing compounds are part of. The residual coal was possibly presumed includes the hydrocarbon compounds： the aromatic hydrocarbon,the fat hydrocarbon,and the oxygen- compounds： alcohols,ethers and pyridine,but also possibly has the amines and the fragrant nitro compound.
