THERMODYNAMIC PROPERTIES OF TERNARY LIQUID MIXTURE OF TOCOPHEROL ACETATE WITH CHLOROFORM AND DIETHYL ETHER AT 293 K

The reported study, measured the ultrasonic velocity (u), density (ρ) and viscosity (η) of ternary liquid mixtures of α-Tocopherol acetate with chloroform and diethyl ether in the concentration range (0 to 0.1 M) at 293K. These experimental parameters can be used to calculate various thermodynamic parameters like free volume (V_f), internal pressure (π_in), Vander-Wall Constant (b) and Gibbs free energy (∆G^*) etc. to identify the strength of molecular interaction. The results so obtained support the formation of complex structure and molecular aggregation through intermolecular hydrogen bonding in the ternary liquid system of α -Tocopherol acetate with chloroform and diethyl ether.
