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.
