ABSTRACT
The equilibrium solubilities of gatifloxacin in four non-aqueous solvent mixtures of N,N-dimethylformamide (DMF,1) + methanol (2), DMF (1) + ethanol (2), DMF (1) + isopropanol (2) and DMF (1) + n-propanol (2) were studied at the temperatures from 273.15 to 318.15 K K under local pressure of 101.1 kPa. The solubility values of gatifloxacin increased with a rise of mass fraction of DMF and temperature for each system. At the same DMF composition and temperature, the mole fraction solubilities of gatifloxacin were largest in the DMF (1) + n-propanol (2) mixture. The attained solubility was represented mathematically by the Jouyban-Acree, van't Hoff-Jouyban-Acree and Apelblat-Jouyban-Acree models acquiring average relative deviations smaller than 2.49 % and root-mean-square deviation smaller than 1.15 10-4.
