Measurement and correlation of the solubility of (1-benzyl-1H-1,2,3-triazole-4-yl)methanol in water and alcohols at temperatures from 292.15 K to 310.15 K
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 gimel h equation. The average relative deviations (ARD) were 1.87%, 1.53%, and 1.71%, and the root-mean-square-deviations (RMSD) were 2.37 x 10(-2), 1.51 x 10(-2), and 2.12 x 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.
