Abstract


The phase transitions in asphaltenes of petroleum fiber-forming pitches and their narrow fractions have been investigated by using of the inverse gas chromatography. The thermodynamic parameters of the organic substances interaction with narrow fractions of petroleum pitch have been calculated.
