Solubility Studies of Amlodipine Besylate in Propylene Glycol + Ethanol Mixtures at Different Temperatures
In this research, the solubility of amlodipine besylate was studied in the propylene glycol + ethanol mixtures at different temperatures (293.2–313.2 K). The study showed that the solubility increases with an increase in propylene glycol concentration, reaching its highest point at w1 = 0.8. Additionally, the solubility values have a positive correlation with temperature, which is typical for the solid solutes. The experimental solubility data were correlated with some well known cosolvency models and the accuracy of these models was investigated with the mean relative deviations (MRDs%) of the back-calculated data. MRDs were 1.2% for the van’t Hoff model, 4.3 and 4.6% for the Jouyban–Acree and Jouyban–Acree–van’t Hoff equations, 1.4% for the MRS model and 2.1% for the modified Wilson model. The apparent thermodynamic parameters (standard state Gibbs energy, enthalpy, and entropy) of dissolution of ADB in the non-aqueous saturated mixtures were also calculated with the van’t Hoff and Gibbs equations at Thm = 303.0 K.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
