N2 - The solubility of (-)-epigallocatechin gallate (EGCG) peracetate in 12 pure solvents (methanol, ethanol, 1-propanol, 1-butanol, 2-propanol, 2-butanol, 1-pentanol, 1-hexanol, 2-methoxyethanol, 2-ethoxyethanol, 2-propoxyethanol, and 2-butoxyethanol) was measured using the static method at the temperature range 278.15-318.15 K under atmospheric pressure. The solubility of EGCG peracetate in the selected solvents increased with increasing temperature in 12 solvents, and the most notable change was found in methanol. The obtained solubility data were correlated with the van't Hoff equation, the modified Apelblat equation, the λh equation, and the nonrandom two-liquid model. Furthermore, solid forms of EGCG peracetate in 12 pure solvents were studied by a scanning electron microscope and X-ray powder diffraction. The obtained solubility values would be helpful in the purification and crystallization process of EGCG peracetate.
