STUDY OF ASPHALTENES FROM THE PETROSATURATED GROUNDS OF AZERBAIJAN
The asphaltenes from crude oil-saturated lands of Azerbaijan are identified and investigated. Infrared spectroscopy to determine the composition of asphaltenes oil before and after hydrotreating the IR specter of the samples showed that the carbon chain of asphaltenes hydrogenated in the presence of the land of oil observed less branching than in the original sample and oil, hydrogenated on the catalyst Al-Co-Mo. All samples contain functional groups and hydrocarbon radicals in the aromatic ring and in the carbohydrate chain (CH2CO, CH2N, etc.). In the aromatic rings is observed 3-, 4-, 5-substitution, they are more intense after hydrogenation on Al-Co-Mo. In the initial sample contains mostly 4-substituted ring.
