ABSTRACT

The interactions of salt trilithium citrate (TLC) with saccharides D(+)-glucose and D(-)-fructose, have been investigated in aqueous medium from density (q) and speed of sound (c) measurements at T = (288.15 318.15) K and experimental pressure p = 0.1 MPa. The apparent molar volume (V/), the partial molar volume (Vo /) and standard partial molar volumes of transfer (DVo /) for both saccharides, from water to aqueous trilithium citrate (TLC) have been calculated from density data. The limiting apparent molar expansibilities have also been calculated. The apparent molar isentropic compression (K/;s), partial molar isentropic compression (Ko /;s) and partial molar isentropic compression of transfer (DKo /;s) have been calculated from speed of sound results. The pair and triplet interaction coefficients have been calculated from partial molar volumes of transfer and partial molar isentropic compression of transfer. A detailed insight into the physicochemical interactions e.g. ion hydrophilic, hydrophilic hydrophilic and hydrophilic hydrophobic interactions in the saccharide-salt system along with the structure-making/struc ture-breaking tendency of the saccharides, have been retrieved through the perusal of these calculated parameters.
