Abstract / Full Text

The solubility of 1,1-bis(3-methyl-4-hydroxyphenyl)cyclohexane (MeBZ) in different pure organic solvents such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, acetone, 1,4-dioxane, ethylacetate, and tetrahydrofuran over a temperature range from 299.15 to 328.15 K at atmospheric pressure were measured by gravimetric method. The solubility increased significantly with increase in temperature in all studied solvents. Among the studied solvents, tetrahydrofuran showed the highest solubility at 328.15 K. The experimental solubilities were corelated with the modified Apelbalt equation and Buchowski–Ksiazczak (λh) equation.The thermodynamic parameters such as enthalpies of solution (\(\Delta H_{{{\text{sol}}}}^{^\circ }\)), Gibbs energy of dissolution (\(\Delta G_{{{\text{sol}}}}^{^\circ }\)), isobaric heat capacity(\(\Delta C_{{p\;{\text{sol}}}}^{^\circ }\)), and entropy of solutions (\(\Delta S_{{{\text{sol}}}}^{^\circ }\)) were calculated using Clark and Glew equation.
