Epigallocatechin gallate (EGCG) is the most abundant and active components in tea. In this text, the density and viscosity of ternary aqueous solution of EGCG containing LiCl/NaCl/KCl were determined at temperatures ranging from 288.15 to 308.15 K at atmospheric pressure. The density data was used to compute the apparent molar volumes (V φ ), limiting partial molar volumes (V φ 0 ), and transfer partial molar volumes (Δ trs V φ 0 ). The viscosity B-Coefficients were calculated from the measured viscosity data using the extended Jones−Dole equation. The values of density and viscosity increased continuously with the increasing of molality of EGCG and decreased with the temperature increasing. The positive values including (V φ , V φ 0 , Δ trs V φ 0 , viscosity B-Coefficients, the free energies of activation for solvent Δμ 1 0≠, and for solute Δμ 2 0≠) and Helper's constant (∂ 2 V φ 0 /∂T 2 ) p close to zero indicated the presence of strong solute−solvent interactions and the structure− making effect of EGCG in the investigated solutions. The apparent molar isobaric expansions (E φ 0 ) decreasing with temperature suggested that the solute−solvent interactions became weaker as temperature increased. These significant parameters could provide necessary data about molecular interactions occurring in simulated body fluids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
