Title
MASS SPECTROMETRIC CHARACTERIZATION OF PERYLENE AND ITS SIGNIFICANCE IN ORGANIC GEOCHEMISTRY
摘要
我们曾用柱色谱结合薄层色谱分离、紫外吸收光谱和荧光光谱测定各种岩样的苝。但样品中的苝是否是一种单一结构?除分子量为252的结构外,是否还有分子量较大的各种烷基衍生物?我们已觉察到上述手段对苝骨架周围的基团反映是不很灵敏的。因此,我们决定对苝进行毛细管气相色谱-质谱-计算机联用鉴定研究,还想对苝的地球化学意义再作一次较深入的探讨。
Abstract
The perylene of some samples from certain basins of China is examed by means of GC/MS/computer system.The perylene fractions,which contain mainly the compounds of molecular weight 252,and are devoid of those less than 252, were separated from the sample exiracts by means of column chromatograpny and thin layer chromatography. Mass spectrogram of the perylene isolated by glass capillary gas chromatography in our researchs are identical with the standard one.
