ABSTRACT

The solubility data of 2-mercaptobenzimidazole in different organic solvents including methanol, ethanol, isopropanol, n-propanol,1-butanol, toluene, cyclohexane, ethyl acetate, acetone, acetonitrile, 1,4-dioxane and 2-butanone were determined experimentally by the isothermal saturation method over a temperature range from T = 278.15 K to T = 318.15 K under P = 101.1 kPa. In the study temperature range, the data increased with increasing temperature, and obeyed the following order from high to low: 1,4-dioxane greater than acetone greater than 2-butanone greater than methanol greater than ethanol greater than n-propanol greater than 1-butanol greater than isopropanol greater than ethyl acetate greater than acetonitrile greater than toluene greater than cyclohexane. The determined solubility data of 2-mercaptobenzimidazole in these solvents were correlated by the modified Apelblat equation and Buchowski-Ksiazaczak h equation. The maximum values of root-mean-square deviation (RMSD) and relative average deviation (RAD) were 2.0510-4 (in
