ABSTRACT

The solubility data of 5-nitrosalicylaldehyde in methanol, ethanol, n-propanol, isopropanol, 1-butanol, acetonitrile, acetone, cyclohexanone, ethyl acetate, 1,4-dioxane, toluene and water were determined experimentally by using the isothermal dissolution equilibrium method within the temperature range from (273.15 to 313.15) K under pressure of 101.2 kPa. The results in mole fraction increased with a rise of temperature. At a certain temperature, these values decreased according to the following order: acetone greater than 1,4-dioxane greater than ethyl acetate greater than cyclohexanone greater than toluene greater than acetonitrile greater than methanol greater than ethanol greater than isopropanol greater than n-propanol greater than 1-butanol greater than water. Moreover, these solubility values were correlated by the modified Apelblat equation and Uh equation, The maximum values of root-mean-square deviation (RMSD) and relative average deviation (RAD) were 3.25 e10-4 and 6.12 %, respectively. In addition, the (KAT-LSER) model was applied to analyze the effect of the solute-solvent intermolecular interactions on the solubility in pure organic solvents.
