ABSTRACT

The 4-nitrobenzonitrile solubility in the four mixtures of (ethyl acetate + methanol), (ethyl acetate + ethanol), (ethyl acetate + n-propanol) and (ethyl acetate + isopropanol) over temperature range from (278.15 to 318.15) K was obtained experimentally. From the analysis results in the present paper, we found that the equilibrium 4-nitrobenzonitrile solubility in ethyl acetate (1) + (methanol, ethanol, n-propanol and isopropanol) (2) mixtures (0-100 % by w/w) increased with the amount of the ethyl acetate and the temperature increasing. The largest solubility of 4-nitrobenzonitrile was in neat ethyl acetate at T = 318.15 K (1.346x10-3 in methanol, 1.159x10-2 in ethanol, 1.082x10-2 in n-propanol, 0.8765x10-3 in isopropanol and 14.22x10-2 in ethyl acetate). The lowest solubility of 4-nitrobenzonitrile was observed in neat isopropanol (0.1624x10-2 at T = 278.15 K). The 4-nitrobenzonitrile solubility dependence upon temperature and mass fraction of ethyl acetate was mathematically described by using the Jouyban-Acree, van't Hoff-Jouyban-Acree and Apelblat-Jouyban-Acree models. The acquired values of RAD and RMSD were not greater than 2.13 % and 11.72x10-4, respectively.
