Volumetric properties of transfer of D(+)-glucose and sucrose from water to mixed aqueous solutions at 298.15 K

2549-2554Apparent molar volumes (ϕv) and apparent molar compressibilities (KS,2,ϕ) of D(+)-glucose and sucrose have been determined in aqueous solutions of potassium chloride (0.5, 1.0, 2.0 and 4.0 mol kg-1), strontium chloride (0.25, 0.5 and 2.0 mol kg-1), barium chloride (0.25, 0.5 and 1.0 mol kg-1) and guanidine hydrochloride (0.25, 0.5 and 2.0 mol kg-1) at 298.15 K from their density and sound velocity data. Partial molar volumes (Vo2) and adiabatic compressibilities (KoS,2) at infinite dilution have been determined from the respective apparent molar properties and used to calculate partial molar volumes (Vo2,tr) and adiabatic compressibilities KoS,2,tr) of transfer for saccharides from water to aqueous potassium chloride, strontium chloride, barium chloride and guanidine hydrochloride solutions. Transfer parameters have been discussed in terms of solute-cosolute interactions on the basis of a cosphere overlap hydration model. Interaction coefficients have also been calculated from transfer parameters
