Gas chromatography-mass spectrometry-computer assisted analysis of the acidic fraction of Miocene Aleksinac shale bitumen (26 million years old) has shown a great variety of organic compounds. Samples obtained from both benzene and benzene-methanol extracts were investigated and found to contain a homologous series of γ-lactones (C7-C15). These lactones possibly represent the only indication of unsaturated acids present during the shales deposition. In addition to the γ-lactones, straight chain aliphatic monocarboxylic acids (C6-C12), dicarboxylie acids (C6-C19), as well as many aromatic acids have been detected. 相似文献
