ABSTRACT
This work presents measurements of the solubility of adipic acid in water, acetic acid, acetic acid-water mixture (ratio of 1:1 v/v), cyclohexanol and cyclohexanone at the temperature ranging from 303.0 to 403.0 K. The reliability experimental method used in this work for studying the solubility of adipic acid was verified using the published solubility data at low temperatures. The modified Apelblat equation was applied in order to correlate the solubility of adipic acid in the above-mentioned solvents. The results showed that data obtained from our method were acceptable for measuring the solubility of adipic acid at high temperatures. The solubilities of adipic acid obtained from the modified Apelblat equation fitted well with the experimental data. The total average relative deviation was 2.55%. Moreover, the molar enthalpy and the molar entropy of dissolution of adipic acid in water, acetic acid, acetic acid-water mixtures, cyclohexanol and cyclohexanone at temperatures ranging from 303.0 to 403.0 K were calculated.
