Abstract
While continuing investigations into the nature of hetero-organic oil compounds of South Uzbekistan, the authors examined the individual composition of some aromatic compounds of this series, contained in concentrates of nitrogen bases of commercial Dzharkurgan petroleum. A study was made of the composition of nitrogen bases of Dzharkurgan crude oil (South Uzbekistan) by high-speed liquid chromatography and microhydrogenolysis under gas-chromatographic conditions. Mass-spectra were obtained for hetero-organic compounds and their picrates. The structure of the following individual compounds was established: 4-methylquinoline, quinoline, isoquinoline, 3-ethylquinoline, 2,4-dimethylthiazole, 2-phenyl-4-methylthiazole and 2-phenyl-4,5-dimethylthiazole. It was shown that alkylpyridines (methyl- and dimethyl-substituted) and 2(8)-methyl(ethyl)quinolines are present in the concentrate of nitrogen bases. 7 references.
