In this paper, we chose gravimetric analysis to measure the solubility of 4biphenylcarboxylic acid in nine pure and binary mixed organic solvents from T = 293.15 to 328.15 K. It is demonstrated that with the increase of temperature, the solubility of 4biphenylcarboxylic acid in each of the solvents increases. Meanwhile, the experimental data are fitted with five classical models: Apelblat, van't Hoff, λh, nonrandom two-liquid (NRTL), and UNIQUAC. The maximum relative average deviations in pure solvents and binary mixed solvents are 0.935 and 1.563%. The fitted result meets the requirements. In addition, this paper also studies the thermodynamic parameters of 4-biphenylcarboxylic acid in the dissolution process and calculates the mixing Gibbs free energy, mixing enthalpy, and mixing entropy during the dissolution process. All of the mixing Gibbs free energy values are less than 0, which shows that the dissolution process is spontaneous.

“…Derived from the Clausius–Clapeyron equation, the Apelblat equation is a semiempirical model broadly utilized in the solubility correlation with temperature. − The equation can be expressed as eq . where x 1 denotes the mole fraction solubility of DAAM; T is the absolute temperature; and A , B , and C represent adjustable constants.…”

For the design, optimization, and control of the solution crystallization process of diacetone acrylamide (DAAM), solid−liquid equilibrium data in various solvents are critical. In this work, the solubility of DAAM in 15 pure solvents, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, 1-hexanol, isobutanol, n-pentanol, isopentanol, 2-butanone, acetone, ethyl acetate, 2-pentanone, acetonitrile, methyl acetate, and ethyl formate, is analyzed by a gravimetric method under ambient pressure and temperatures ranging from 272.05 to 323.65 K. The solubility values in all of the solvents are positively correlated with temperature. The solubility of DAAM can be satisfactorily correlated by the Apelblat equation, λh equation, nonrandom two-liquid (NRTL) model, and Wilson model, and the calculated solubility agrees well with the measured results. The obtained maximum relative average deviation (RAD) and root-mean-square deviation (RMSD) are 2.44 × 10 −2 (n-propanol, NRTL model) and 2.40 × 10 −2 (methanol, λh equation), respectively. The most suitable model is the Apelblat equation.

“…In the pharmaceutical industry, solution crystallization has been used to extract and purify propylparaben crystals . For the design and optimization of the crystallization process, solubility and dissolution thermodynamics are two indispensable parameters to be considered. − Especially for the solution crystallization process of propylparaben, the solubility data determine which method should be used to generate supersaturation (cooling or evaporation) during crystallization and the product yield of the process. Moreover, the dissolution thermodynamics can be used to design an industrial crystallizer when it comes to heat transfer and balance.…”

The solubility data of propylparaben in polar and apolar solvents were first measured at T = (283.15−323.15) K using the shake flask method. The results show that solubility of propylparaben in all selected solvents increases proportionally with temperature, and at a high temperature (323.15 K), propylparaben is most soluble in acetone, followed by isopropanol, 1-propanol, ethanol, methanol, ethyl acetate, 1-butanol, butyl acetate, methyl acetate, isobutanol, acetonitrile, and water. To mathematically represent the experimentally measured solubility data, the modified Apelblat model, Wilson model, and NRTL model were applied. The difference between experimentally measured and predicted values was described by the percentage of averaged relative deviation. The best correlation of solubility versus temperature with the highest accuracy was obtained using the modified Apelblat model. Dissolution thermodynamics of propylparaben in different solvents at different temperatures were calculated and discussed to study the dissolution mechanism of propylparaben in different solvents.
