Thermodynamic Interaction Studies of D(+) Galactose and D(+) Lactose Mono Hydrates in Aqueous Sodium Butyrate Solution at 308K Temperatures

The density and viscosity of D(+) galactose and D(+) lactose mono hydrates in aqueous solution of sodium butyrate solutions have been determined experimentally at 308K. The results obtained from density and viscosity measurements have been used to calculate the apparent molal volume , partial molal volume , transfer volume at infinite dilution A and B coefficient, and Sexperimental 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.
