The partial molar heat capacity, expansion, isentropic, and isothermal compressions of thymidine in aqueous solution at T = 298.15 K

Abstract

Solution densities have been determined for aqueous solutions of thymidine at T = (288.15, 298.15, 303.15, and 313.15) K. The partial molar volumes at infinite dilution, V 2 ∘ , obtained from the density data were used to derive the partial molar isobaric expansion at infinite dilution for thymidine at T = 298.15 K, E 2 ∘ { E 2 ∘ = ( ∂ V 2 ∘ / ∂ T ) p } . The partial molar heat capacity at infinite dilution for thymidine, C p , 2 ∘ , at T = 298.15 K has also been determined. Sound speeds have been measured for aqueous solutions of thymidine at T = 298.15 K. The partial molar isentropic compression at infinite dilution, K S , 2 ∘ , and the partial molar isothermal compression at infinite dilution, K T , 2 ∘ { K T , 2 ∘ = - ( ∂ V 2 ∘ / ∂ P ) T } , have been derived from the sound speed data. The V 2 ∘ , E 2 ∘ , C p , 2 ∘ , and K S , 2 ∘ results for thymidine are critically compared with those available from the literature.
