“…As the mass fraction w of GA and AA (SA) increases, the solubility of SA (AA) increases. The phenomenon that the solubility of these three acids interacts with each other can also be observed in the literature. − Meanwhile, it can be seen from the difference between the maximum and minimum solubility of the solubility at the same temperature in the figures that the added component has a greater influence on AA than SA. The increase of the solubility is caused by a multifaceted effect of hydrogen bonding, van der Waals interactions, ionic solute–solvent interaction, and so forth. , The interactions between ethyl acetate, GA, and SA (AA) may have an effect on the attractive force, which affects the solvent–solute interaction and causes co-dissolution .…”

The solid–liquid equilibrium of succinic acid in various mass fractions of the glutaric acid + adipic acid + ethyl acetate mixture and adipic acid in various mass fractions of the succinic acid + glutaric acid + ethyl acetate mixture was measured by the dynamic method within the temperature range of 299.12 to 343.56 K under atmospheric pressure. The results show that the solubility of succinic acid and adipic acid increases with the increasing temperature. The solubility of succinic acid in ethyl acetate increases with the increase of mass fraction of glutaric acid and adipic acid in the mixed solvent at the same temperature. Similarly, the solubility of adipic acid in ethyl acetate also increases with the increase of mass fraction of succinic acid and glutaric acid in the mixed solvent. The experimental data of solubility were correlated by the Apelblat equation, the Wilson equation, and nonrandom two-liquid equation. All equations can be well applied, and the Apelblat equation has the better fitting effect. In addition, the thermodynamic properties of the mixing processes in the ternary and quaternary mixed system were calculated based on the nonrandom two-liquid model, including the mixing enthalpy, the mixing entropy, and the mixing Gibbs free energy.

“…Derived from Nývlt's and Kubota's methods, Sangwal suggested two models for interpreting the effects of additives on the nucleation kinetics in cooling crystallization. One of the models is named self‐consistent Nývlt‐like equation, [ 12 ] in which the complicated unit of Nývlt's nucleation constant was simplified by a power law expression, related to the nucleation rate and maximum supersaturation. Another one is called classical 3D nucleation theory‐based approach.…”

Two theoretical methods, self‐consistent Nývlt‐like approach and Sangwal's classical 3D nucleation theory‐based method, are employed to analyze the effects of additives (sodium sulfate) on the nucleation behavior of taurine. By correlating the measured metastable zone width of taurine containing different sodium sulfate concentrations, with saturation temperature and cooling rate, nucleation kinetic parameters in both two methods are determined. Fitting results demonstrate that higher sodium sulfate concentration results in the increase of solid–liquid interfacial energy γ, contrarily higher saturation temperature has the opposite effect thus changing of nucleation rate. The molecular modeling techniques are then applied to investigate the changes in the morphology of taurine which caused by the presence of sodium sulfate. Through molecular dynamic simulations, the interaction energy of sodium sulfate with taurine crystal faces are obviously larger than those of taurine and these differences on the (011) and (11‐1) are more significant than those on (021) and (111) faces. As a result, the growth of (011) and (11‐1) faces is inhibited and the morphology of taurine crystal is modified from needle to columnar. The influence of sodium sulfate on taurine studied in this work provides theoretical guidance for industrial production.

“…The interfacial free energy is the energy required to create a new solid/liquid interface for the formation of crystals in liquid solutions, while the pre-exponential factor is related to the attachment rate of solute molecules to a cluster in the formation of crystals. The influences of impurities on the nucleation parameters have long been investigated using induction time or MSZW data with the addition of different impurities in solutions for a variety of compounds [4][5][6][7][8][9][10][11][12][13][14].…”

Induction time and metastable-zone-width (MSZW) data for aqueous L-glycine solutions in the presence of L-arginine impurity were experimentally measured using a turbidity probe in this study. The nucleation parameters, including the interfacial free energy and pre-exponential nucleation factor, obtained from induction time data, were compared with those obtained from MSZW data. The influences of lag time on the nucleation parameters were examined for the induction time data. The effects of L-arginine impurity concentration on the nucleation parameters based on both the induction time and MSZW data were investigated in detail.
