摘要：

Relationships between solvent extractive ability with coal tar pitches and Hildebrand's solubility parameter have been studied. In addition, taking into account Hansen's solubility parameter components, relationships between these and solvent effectiveness in coal tar pitch extractions have been studied. It is proved that organic solvents with a high solubility parameter dispersive component are the best coal tar pitch solvents, providing their polarity and their ability to give rise to hydrogen bonding interactions do not exceed certain limits.
