摘　　要：本研究为分析枣庄煤中的有机成分,采用的是甲醇溶剂对枣庄煤进行了微波萃取,并利用GC/MS对萃取物的组成进行了分析.结果表明枣庄煤甲醇萃取物中GC/MS可检测到化合物70种,其中芳香烃占多数,其次是脂肪烃,含杂化合物占少数,含部分其他物质.这可推测枣庄煤样中可能含有的烃类物质为芳香烃、脂肪烃,含氧化合物有酮、吡啶和酸类,还可能有胺类和芳香硝基化合物.For further analysis of organic components in the zaozhaung coa,this paper introduced that methanol solvent is used to extract by Microwave extraction of zaozhuang coal in Zaozhuang,and the composition of the extracts were analyzed by GC/MS. The results show that 70 new compounds could be detected from Zaozhuang coal by GC/MS,of which aromatic hydrocar-bons are the majority,followed by aliphatic hydrocarbons,hetero compound minority,and some other compounds are part of. The zaozhaung coal was possibly presumed includes the hydrocarbon compounds：the aromatic hydrocarbon,the aliphatic hy-drocarbon,and the oxygen-compounds：ketone ,pyridine and acids but also possibly has the amines and the fragrant nitro compound.
