Gas Chromatographic Analysis of Hydrogenated Anthracene Oil -l Yasuo MIKI*, " and Yoshikazu SUGIMOTO-

Abstract

The qualitative and quantitative analyses of hydrogenated anthracene oil have been carried out on the analytical system consisting of a Hewlett-Packard 5880 gas chromatograph with a SP-2100 fused-silica capillary column (50 x 0.2 mm) and a 5992 mass spectrometer. The chromatographic operating conditions are summarized in Table 1. Thirty five polynuclear aromatics, the main components of anthracene oil, were hydrogenated and used as the standard samples for the gas chromatographic analsis of hydrogenated anthracene oil. The gas chromatogram of a mixture obtained by hydrogenation of pyrene and the identified molecular structures are shown in Fig.1. Perhydro-compounds and partially hydrogenated aromatics were obtained and separated. A similar chromatogram was obtained from each hydrogenated mixture of standard aromatics. The gas chromatogram of hydrogenated anthracene oil is shown in Fig.4. The chromatogram was analysed in reference to those of the standard mixtures and of anthracene oil and by comparison with the GC-MS analysis. The results are listed in Table 2. Out of 335 compounds, 284 were separated chromatographically.
