SOLUTE-SOLUTE AND SOLUTE-SOLVENT INTERACTIONS STUDIES OF SACCHARIDES IN AQUEOUS SODIUM BUTYRATE SOLUTION AT 308K TEMPERATURES

Density and viscosity of D (+) galactose and D (+) lactose mono hydrates in aqueous solution of sodium butyrate solutions have been determined experimentally at 308 K. The results obtained from density and viscosity measurement have been used to calculate the, apparent molal volume фv, partial molal volume ф0 v, transfer volume ∆ф0 tr at infinite dilution, A and B coefficient and Sv experimental slope. The results are interpreted in terms of solute-co- solute and solute-solvent interactions in these systems. It has been observed that there exist strong solute-solvent and solute-solute interactions and complex formation between in these ternary systems. The properties of the D (+) galactose and D (+) lactose mono hydrates in aqueous solution of sodium butyrate solutions are discussed in terms of the structure making and hydrogen bonding effect.
