Abstract
The equilibrium molar solubility of 2-hydroxybenzoic acid (salicylic acid, SA) in pseudo-binary mixed solvents of choline chloride/propylene glycol deep eutectic solvent (ChCl/PG DES, 1:3 molar ratio) and water was determined by a shake flask method at 293.15-313.15 K and ambient pressure (85 kPa). Based on the results, the maximum solubility of SA was observed in neat DES at 313.15 K (0.7604 mol·L−1) whereas it was minimum in neat water at 293.15 K (0.0112 mol·L−1). X-Ray power diffraction analysis of solid phase presented no polymorphic transformation or solvate formation in the experiments. Moreover, the molar solubility of SA was modeled mathematically with various cosolvency models attaining the average percentage deviations smaller than 6.1%, except for the modified Wilson-van’t Hoff (12.6%). Further, more favorable and entropy-driven of SA dissolution in ChCl/PG DES-rich mixtures was achieved from the apparent thermodynamic analysis.
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.
