| 摘 要： | 在微波辅助下用等体积的CS2-丙酮为溶剂对锡林浩特褐煤进行萃取,萃取物用GC/MS分析.结果表明:萃取物中共检测到70种有机化合物,可分类为烷烃、烯烃、芳烃、酚类、醛类、酮类、脂肪酸、酯类和含氮化合物.含氮化合物含量和种类均为最多,共26种含氮化合物,相对含量为54.36%,推测因为CS2和丙酮之间存在缔合关系,促使含氮化合物从煤中被萃取出来.

| Abstract: | Xilinhaote lignite(XL) has been extracted using CS2/acetone(1∶1 in volume) mixed solvent under microwave irradiation(MI).The extractable fraction is analyzed with gas chromatography/mass spectrometry(GC/MS).70 compounds are identified from extractable fraction,and they can be classified into 9 groups components: alkanes,alkenes,arenes,phenols,aldehydes,ketones,fatty acids,esters and organonitrogen compounds(ONCs).The ONCs is the most abundant compounds whose relative content is 54.36%,and there are 26 ONCs detected in the extractable fraction.CS2 and acetone have π-π interaction to promote the extraction yield of ONCs from coal. |
