The solubility of dodecanedioic acid in ethanol, acetic acid, acetone, butanone, 3-pentanone and ethyl acetate has been measured at temperatures ranging from (288.15 to 323.15) K by a static analytic method at atmospheric pressure. At a given temperature, the order of solubility is ethanol greater than acetic acid greater than acetone greater than butanone greater than 3-pentanone greater than ethyl acetate. Molecular modeling study using Materials Studio DMol3 (Accelrys Software Inc.) indicated that the solubility of dodecanedioic acid depends not only on the polarities of the solvents but also on the interactions between dodecanedioic acid and solvent molecules. Furthermore, the modified Apelblat equation was used to represent the temperature dependence of the mole fraction solubility. Finally, the molar Gibbs energy, enthalpy, and entropy of the solution were calculated using the fitting parameters of the modified Apelblat equation.
