The dissolution of compounds based on 1-imino-2-phenyl-1H-inden-3-amine with fragments of 3, 5-diamino- 1,2,4- and 2,5-diamino-1,3,4-thiadiazoles in DMF and ethanol is investigated by means of isothermal saturation with spectrophotometric concentration monitoring in the temperature range of 298-318 K. Characteristics of the dissolution of the products of condensation with compositions 1 : 2, 2 : 1, and 2 : 2 in individual solvents are presented. Thermodynamic parameters of the dissolution of the synthesized compounds are calculated.
