The organic part of bituminous Sands (BS) is a chemical raw material of complex and unstable composition. The physical and chemical properties and composition of this raw material depend on the BS Deposit, the method of separation of the organic part, methods and equipment for analysis. The organic component-natural bitumen-is an oil dispersed system, the dispersed phase of which is formed by high – molecular components-resins and asphaltenes; the dispersed medium is made up of lighter hydrocarbons. It was found that traces of tungsten oxide (V), primary and secondary alcohols, and esters were found in the bituminous rock of the Deposit. It was found that natural bitumen extracted from BS contains saturated hydrocarbons: linear: n-heptane, n-decane and cycloparaffins: 1-phenyldodecane, methylcyclohexane, various primary and secondary alcohols, ketone and esters.
