Abstract
In this paper, we focused on solubility and solution thermodynamics of 3-amino-1-adamantanol. By gravimetric method, the solubility of 3-amino-1-adamantanol was measured in H2O, ethanol, methanol, n-propanol, n-butanol, tetrahydrofuran and (H2O+ethanol) binary solvent mixtures from 278.15K to 328.15K under atmosphere pressure. The solubility data of all solvent were fitted using modified Apelblat model and Buchowski–Ksiazaczak λh model. The solubility data of (H2O+ethanol) binary solvent mixtures were fitted using the two of the combined nearly ideal binary solvent/Redlich–Kister (CNIBS/R–K) model and Jouyban–Acree model. Computational results showed that the Apelblat equation provides a superior correlation in the pure solvent systems or the mixed solvent systems with a given initial composition. In addition, the thermodynamic properties of the solution process, including the Gibbs energy, enthalpy, and entropy were calculated by the van't Hoff analysis.
