| مستخلص: |
The solubility of d-pantolactone in water, ethanol, methanol, ethyl acetate, and ethanol-water mixtures was determined at temperatures between (278.15 and 318.15) K using a digital densitometer by a static method. The measured solubility data were correlated with Apelblat equation, van't Hoff equation, nonrandom two liquid model, and Wilson model. The results indicate that the Wilson model is the most suitable model in pure solvents and the Apelblat model is the best model in ethanol-water mixtures. [ABSTRACT FROM AUTHOR] |
