【摘要】 为了解影响柴油机尾气污染排放的市售 0号柴油品质 ,采用毛细管柱气相色谱 -质谱联用技术并结合柱层析溶剂洗脱前处理方法 .结果显示正常油样由 6 4～ 75种化合物组成 ,主要为烷烃、芳香烃 ;异常油样含有 12 .17%～ 2 8.92 %的高级脂肪酸与高级醇及其酯类等 .说明目前市售柴油质量不稳定 ,存在以劣质油冒充轻质油销售的情况更多还原

【Abstract】 Gas chromatography-mass spectrometry(GC-MS)coupled with solvent elution and column chromatographic separation techniques is used to find outthe quality of #0 diesel oil being sold at the market which affects the diesel engines.The results show that the samples of normal oil are composed of 64～75 kinds of chemical compounds,mainly alkane and arene;the samples of the abnormal oil contain 12.17%～29.92% higher fatty acid,higher alcohols and their esters etc.At present the quality of diesel oil in the market is unstable,there exists the case of passing poor quality oil off as light oil at present.更多还原
