摘要：
The solubility of caffeine in water between 323.15 and 353.15 K was measured using the balance method. The solubility trend was modeled by use of the modified Apelblat equation and Yaws equation. The calculated solubility values according to the two empirical equations compare favorably with the experimental data. Besides, the relationship between supersaturated ratio and induction time was studied with the method of laser, basing on which, the surface tension of caffeine at 283.15 K, 293.15 K and 298.15 K in water was calculated.
