Abstract
The interactions of polyhydroxy solutes d(+)-glucose and d(â)-fructose with aqueous solutions of triammonium citrate (TAC) as a function of temperature have been enquired upon by combination of volumetric and ultrasonic studies. Densities and speed of sound of d(+)-glucose and d(â)-fructose in (0.2, 0.4 and 0.6)â¯mol·kgâ1 aqueous solutions of triammonium citrate (TAC) are measured at Tâ¯=â¯(288.15, 298.15, 308.15 and 318.15)â¯K and experimental pressure pâ¯=â¯0.1â¯MPa. The apparent molar volume, VÏ, the partial molar volume VÏo, and standard partial molar volumes of transfer, ÎVÏo for d(+)-glucose and d(â)-fructose from water to aqueous solutions of triammonium citrate (TAC) have been calculated from density data. Apparent molar isentropic compression, KÏ,s, partial molar isentropic compression KÏ,so and partial molar isentropic compression of transfer, ÎKÏ,so have been calculated from ultrasonic speed data. The expansibility parameter (âVÏ0/âT)p and its derivative (â2VÏ0/â2T)p along with pair (VAB, KAB) and triplet (VABB, KABB) interaction coefficients have also been calculated. The results have been interpreted in terms of solute-solute and solute-solvent interactions in these systems.
