Abstract
In this paper, the solubility and dissolution thermodynamic properties of dodecanedioic acid (DDDA) in four binary-mixed solvents (ethyl acetate + ethanol, ethyl acetate + acetic acid, and ethyl acetate + acetone) were investigated. The gravimetric method was employed to determine the mole fraction solubility of DDDA in different solvent ratios from 288.15 K to 328.15 K under the atmosphere. In the binary solvents of ethyl acetate + ethanol and ethyl acetate + acetic acid, when the composition was varied the solubility change was not monotonous, and the phenomenon of co-solvency occured. Furthermore, four models were employed to fit the solubility data, among which the modified Apelblat equation and CNIBS/R-K model had better fitting results. Finally, the dissolution thermodynamic properties of DDDA were analyzed based on the modified Van’t Hoff equation.
