The partial molar volumes at T = (288.15 to 313.15) K, and the partial molar heat capacities and expansions at T = 298.15 K of cytidine, uridine, and adenosine in aqueous solution

Solution densities have been determined for aqueous solutions of the nucleosides cytidine, uridine, and adenosine at T = (288.15, 298.15, 303.15, and 313.15) K. These results were used to calculate the partial molar volumes at infinite dilution, V2∘, for the nucleosides. The partial molar expansions for the solutes at infinite dilution and at T = 298.15 K, E2∘{E2∘=(∂V2∘/∂T)p}, were derived from the V2∘ results. The partial molar heat capacities at infinite dilution for the nucleosides, Cp,2∘, have also been determined at T = 298.15 K. These V2∘, E2∘, and Cp,2∘ results are critically compared with all of the results available from the literature.
