THE BASIC RESULTS AND CONCLUSIONS


It is shown, that depending on the vanadium maintenance, asphaltenes neftej deposits of Tatarstan are divided into two basic structural types. Asphaltenes with rather low maintenance of vanadium (less than 0,1 mas.
%) have large polyaromatic fragments in molecular composition, to 50 % of free radicals at allocation of the specified asphaltenes re - combine. The asphaltenes enriched by vanadium (more than 0,3 mas. %), have more volume form of molecules and contain polyaromatic fragments in structure interior.
It is positioned, that interaction vanadilovyh with the fragments of the asphaltenes containing not coupled electrons does not result in complexes to formation of diamagnetic complexes.
The tendency to inverse relationship of the maintenance of free radicals from the maintenance vanadilovyh complexes in asphaltenes neftej, enriched by vanadium, is mainly caused by change of a parity polyaromatic and nafteno-alifaticheskoj parts as a part of average structure of asphaltenes.
The new methodical approach is developed for the analysis of paramagnetics in neftjah and the asphaltenes, consisting in unification of relative units of measure of concentration vanadilovyh complexes and free radicals in neftjah and asphaltenes.
For the first time spectral factors for a degree estimation kondensirovannosti aromatic system (Оі60 (є«5«) and alifatichnosti (D2S5o/Di6oo) asphaltenes are offered.
Structural similarity of polyaromatic fragments of technogenic asphaltenes from the rests of petrochemical processes (pyrolysis and ethyl benzene synthesis) with similar fragments of oil asphaltenes is revealed.
7. For studying of degree of possible interaction vanadilovyh complexes and free stable radicals as the modelling systems characterised by presence of stable not coupled electrons and absence of connections of paramagnetic vanadium, for the first time it is offered to use asphaltenes of the rests of some petrochemical processes, for example, pyrolysis and ethyl benzene synthesis.
Century As a part of heavy resin of pyrolysis is identified for the first time stable fenalenilnyj a radical, and similarity of the organisation of hydrocarbonaceous systems of a technogenic origin and natural oil systems is confirmed. 1. 117
