摘要：采用酸液萃取的方法从煤液化油中提取碱性氮化物,气相色谱-质谱联用(GC-MS)和氮化学发光检测器(GC/NCD)进行定性定量。从分析结果可见,碱性氮化物可以通过酸液萃取与油样达到较完全的分离。用GC-MS定性出全馏程煤液化油中含有38种碱性氮化物,主要为吡啶类、苯胺类以及喹啉类氮化物。用GC/NCD对18种全馏程煤液化油中的碱性氮化物定量分析,结果显示其占碱性氮化物总量的88.9%,其中吡啶类占碱性氮化物总量的24.48%,苯胺类占37.98%,喹啉类占26.48%。
Basic nitrogen compounds in coal liquefaction oil were extracted by acid extraction method and analyzed by gas chromatography-mass spectrometry（GC-MS）and gas chromatography-nitrogen chemiluminescence detection（GC-NCD）.It can be seen from the analysis that basic nitrogen compounds were clean separated out from the oil sample through acid extraction.38 kinds of basic nitrogen compounds in the full range of coal liquefied oil were determined by GC-MS,and they were mostly pyridine class,aniline class and quinoline class.18 kinds of basic nitrogen compounds were quantified by GC/NCD and the content accounted for 88.9% of total basic nitrogen compounds,in which the pyridine class accounted for 24.48% of total basic nitrogen compounds,aniline class accounted for 37.98%,and quinoline class accounted for 26.48%.
