ABSTRACT
The solubility of diosgenin in methanol, ethanol (95%), isopropanol, acetone, acetic ether, and propyl acetate were measured at temperatures from (295.15 to 330.15) K using the synthetic method by a laser monitoring observation technique at atmospheric pressure. Its corresponding (solid + liquid) equilibrium data will provide essential support for industrial design and further theoretical studies. The solubility data of diosgenin in isopropanol, acetone, ethanol (95%), and acetic ether were correlated with Apelblat equation, and the experimental data of diosgenin in methanol and propyl acetate were also correlated with the lambda h model. The calculated values were good in agreement with the experimental values.
