文摘
- •
Solubility of d-(−)-quinic acid in pure and binary solvents was determined.
- •
The solubility data were fitted using four models.
- •
Good correlation was existed between experimental and calculated solubilities.
- •
Results showed that the Apelblat model superior to the λh, Wilson and NRTL model.
- •
The Gibbs free energy, enthalpy, entropy were calculated by the van’t Hoff analysis.
