The oil is co-featured bout dispersion and by influencing the nature of mutually-interacting between the parish-contact, resins and asphaltene-mi, it becomes possible to control the processes of structure-turoobrazovaniya in the oil system. Therefore, for the rose-ciency technologies extraction of residual oil using carbon-hydrogen solvent was conducted to study the pro-asphaltene precipitation process oil with an increase in its concentration of n-hexane. As a result of experiments, it was found that pro-process asphaltene precipitation with n-hexane from the oil West but Salymmestorozhde-tion attended by at least two groups of substances, which differ in the various content-eat aromatic fragmentsing and sulfoxide groups. In the first asphaltenes precipitated with a maximum content of aromatic moieties and sulfoxide groups. Soviet-seater with asphaltenes from crude oil West Salymcoprecipitated alkanes of different mole- cular-weight that Vero yatno form a skin during the circle-asphaltene particles.
