The paper reviews research on the molecular structure of binder and electrode pitches by physicochemical analytical methods. The research demonstrates the effect of modifications on changes in the molecular structure of binder pitches determined by IR spectroscopy. Additionally, it presents the results of studies on the determination of the polyaromatic composition of the pitches. The author performed a comparative analysis of the results of studies on the determination of the structural and group composition of coal and petroleum pitches. Physicochemical methods for determining the mesophase structure of pitches are described.
