摘要

In order to answer the question: is a solute water "negatively expansible" in tetrahydrofuran or not (?), a comparative analysis of own and literature data on the temperature-dependent partial volumes at the infinite dilution of water isotopologues in tetrahydrofuran have been carried out. Used for computing the limiting partial (apparent) volumes of water isotopologues, densities of H_2O and D_2O solutions in the solvent studied, with the solute mole fractions ranging up to ～0.043, were measured with an error of 1.5 · 10~(-5) cm~3 · mol~(-1) at (278.15, 288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure using a vibrating tube densimeter. It has been shown that the partial molar volume of H_2O or D_2O at infinite dilution increases with rising temperature; that is, the isotopically distinguishable solutions of water in tetrahydrofuran do not have the unusual structure-packing behavior being characteristic of the water-containing system with the so-called phenomenon of "negative partial molar expansibility".
