Abstract—The solubility of the macroheteroring with indanedione-1,3 and benzene fragments in normal
monohydric alcohols C₁–C₄ was measured under isothermal conditions. The temperature dependence of the
solubility was used to calculate the thermodynamic parameters of dissolution of the macroheteroring. The sol-
ubility increased from methanol to butanol, which was accompanied by a decrease in the H and S values.
Thethermodynamic compensation effect was observed.
