| The solubility profile of caffeine in the binary non-aqueous mixtures of N-methyl-2-pyrrolidone (NMP) and eth- anol at different temperatures is determined and the obtained data are fitted to some linear and non-linear cosolvency models including the van't Hoff, the double log-log, the mixture response surface, Yalkowsky, Jouyban-Acree, Jouyban-Acree-van't Hoff, and the modified Wilson models. The measured density data of caf- feine saturated solutions as another physico-chemical property are also correlated with the Jouyban-Acree model and the results are discussed. In order to investigate the accuracy of the applied models, the mean relative deviations (MRD%) of the back-calculated solubility data is calculated. Furthermore, the apparent thermody- namic properties of caffeine dissolution process are also calculated by using van't Hoff and Gibbs equations. |
