The solubilities of (1-benzyl-1H-1,2,3-triazole-4-yl)methanol (BTZM) in water, methanol, ethanol, n-propanol, isopropanol, and n-butanol were measured at temperatures ranging from 292.15 K to 310.15 K by a dynamic method under normal atmospheric pressure. The results showed that it increased with the increasing temperature and the order of solvents was: Order: Methanol > ethanol > n-propanol > n-butanol > isopropanol > water except three points. The solubility data were correlated with the Van't Hoff equation, modified Apelblat equation, and λh equation. The average relative deviations (ARD) were 1.87%, 1.53%, and 1.71%, and the root-mean-square-deviations (RMSD) were 2.37 × 10-2, 1.51 × 10-2, and 2.12 × 10-2, respectively. It was found that the modified Apelblat equation gave the best correlation results. Furthermore, the dissolution enthalpy of BTZM was calculated by the modified Apelblat equation.
