Solubility measurement and data correlation of 2-ethoxy-1-naphthoic acid in twelve pure solvents at temperatures from 278.15 to 323.15 K
The solubility of 2-ethoxy-1-naphthoic acid was determined experimentally in 12 pure solvents (methanol, ethanol, n-propanol, i-propanol, i-butanol, n-pentanol, methyl acetate, ethyl acetate, n-propyl acetate, i-propyl acetate, acetone and acetonitrile) using the gravimetric method in the temperature range of 278.15 K to 323.15 K at atmospheric pressure. The study found that solubility increased with temperature, with acetone exhibiting the highest solubility and acetonitrile the lowest at 298.15 K. Furthermore, the influence of solvent properties on solubility, such as polarity and dielectric constant, was analyzed, showing a positive correlation. Mathematical models (including modified Apelblat, NRTL, Margules, UNIQUAC and λh models) were employed to analyze the dissolution process, with the modified Apelblat model providing the best fit to the experimental data. Additionally, thermodynamic properties of the dissolution process were obtained using the Van’t Hoff equation, indicating an entropy-increasing process with heat absorption. Overall, this study elucidates the solubility behavior and related mechanisms of 2-ethoxy-1-naphthoic acid in various solvents, providing theoretical support for its application in solution systems.
期刊介绍：
The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published.
The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed.
Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered.
The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review.
Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
