合成燃料产品和副产品的详细表征可以提供与合成燃料生产的环境影响和产品的潜在最终用途有关的宝贵信息。本文描述了一种有效的分析方法，用于分离和鉴定这些材料中的含氮多环芳香族化合物（N-PAC），以及从分离馏分的致突变性试验中获得的结果。两种溶剂精制煤液体用于本研究。在中性氧化铝上进行初始分离以获得N-PAC级分。采用硅酸吸附色谱法，根据芳香环系统中氮杂原子的官能度，将N-PAC分离成另外三个基团。含氨基多环芳烃的馏分2用五氟丙酸酐衍生化后进一步分离。（ATT）
The detailed characterization of synfuel products and by-products can provide invaluable information relating to the environmental implications of synfuel production and the potential end uses of the products. This paper describes an effective analytical methodology for the separation and identification of nitrogen-containing polycyclic aromatic compound (N-PAC) in these materials, and the results obtained from mutagenicity assays of isolated fractions. Two solvent refined coal liquids were used for this study. Initial separation on neutral alumina was used to obtain an N-PAC fraction. Silicic acid adsorption chromatography was used to get separation of the N-PAC into three additional groups according to the functionality of the nitrogen heteroatom in the aromatic ring system. Then fraction 2 containing amino polycyclic aromatic hydrocarbons, APAH, was derivatized with pentafluoropropionic anhydride for further separation. (ATT)
