本研究旨在探讨西替利司他的溶解度及溶解热力学。西替利司他的固液平衡数据对于工业应用的初步研究是必不可少的。在278.15 K-323.15 K温度范围内测定了西替利司他在由(水+丙酮)、(水+异丙醇)和(水+乙腈)组成的二元溶剂混合物中的溶解度。采用修正的Apelblat方程、通用共溶模型和Jouyban-Acree模型对西替利司他的溶解度进行关联。通过比较模型,修正的Apelblat方程提供了更准确的实验数据的数学表示。通过van 't霍夫分析计算了溶液的热力学性质,包括吉布斯自由能、焓和熵。
This study aimed to explore the solubility and solution thermodynamics of cetilistat. Data on solid–liquid equilibrium of cetilistat are essential for a preliminary study of industrial applications. The solubility of cetilistat in binary solvent mixtures consisting of (water + acetone), (water + isopropyl alcohol), and (water + acetonitrile) was measured in the temperature range of 278.15 K–323.15 K. The modified Apelblat equation, general cosolvency model and Jouyban-Acree model were used to correlate with the solubility of cetilistat. The modified Apelblat equation provided a more accurate mathematical representation of the experimental data by comparing the models. The thermodynamic properties of the solution process, including the Gibbs free energy, enthalpy, and entropy, were calculated by the van't Hoff analysis.
