| Popis: | 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. |
