Ketones of western siberian Jurassic oils

Separation and Molecular Characterization of Ketones in a Low-Temperature Coal Tar

“…Other aromatic ketones, such as tetralones, acetonaphthones, dihydrophenanthrenones, benzophenones, fluorenones, fluorenyl formaldehydes, anthrones, anthracene formaldehydes, acetylanthracenes, acetylphenanthrenes, acetylfluorenes, and benzofluorenones, were also identified by GC–MS. Indanones and acetonaphthones have been identified in coal tar, and cyclopentenones, tetralones, fluorenones, and benzofluorenones have also been found in other fossil fuels, such as bio-oil, shale oil, ,,, crude oil, ,, and oil sand bitumens. , Several tricyclic diterpenoids (marked with K and J in Figure ) and steroid ketones (marked with F) were tentatively identified in the coal tar by extracting the characteristic mass fragment m / z 300, 298, and 288, respectively. Mass spectra of compounds F and J are shown in Figure S6 of the Supporting Information.…”

“…The results indicate that the Girard T derivatives of ketones with a low molecular condensation degree are easily hydrolyzed, even in neutral aqueous solution. fluorenes, and benzofluorenones, were also identified by GC− MS. Indanones and acetonaphthones have been identified in coal tar, 13 and cyclopentenones, tetralones, fluorenones, and benzofluorenones have also been found in other fossil fuels, such as bio-oil, 53 shale oil, 21,28,31,34 crude oil, 26,29,54 and oil sand bitumens. 55,56 Several tricyclic diterpenoids (marked with K and J in Figure 5) and steroid ketones (marked with F) were tentatively identified in the coal tar by extracting the characteristic mass fragment m/z 300, 298, and 288, respectively.…”

“…Thin-layer chromatography , also had such a problem. The most commonly used method for separating ketones was liquid chromatography, which had a wide range of applications and was used in Colorado shale oil, West Siberian oil, − coal extract, and the Lake Holzmaar sediment extract . A solid-phase extraction (SPE) was specialized in the fractionation of ketones according to functional groups and applied to Irati oil shale .…”

“…GC and/or GC–MS have been widely used for the characterization of ketones from fossil fuels. ,,,,− However, GC is not applicable to the analysis of nonvolatile compounds and lacks enough resolution capability to separate each individual compound. Recently, high-resolution mass spectrometries were used for the molecular characterization of fossil fuels.…”

Radiolytic alteration of biopolymers in the Mulga Rock (Australia) uranium deposit

“…Wu et al, 2012;Wu, 2013). Jurassic oil from the Siberian Platform have been shown to contain n-alkan-2-ones accompanied by various oxygenated aromatic hydrocarbons (Strelnikova and Serebrennikova, 2011). Tuo and Li (2005) reported alkanones oxygenated in positions C 2 to C 5 in an outcropping immature Jurassic coal, although it remains unclear whether potential microbial oxidation took place syn-genetically or through recent weathering of this deposit.…”
