摘要: Abstract Density and ultrasound speed were measured accurately for diglycine + water, triglycine + water, diglycine + water-polyethylene glycol 400 (PEG400) triglycine + water-PEG400 solutions at T = (293.15, 298.15, 303.15 308.15) K. The results used in evaluating thermodynamic properties as apparent molar volumes ( V O ) isentropic compressions K SΦ of diglycine triglycine water PEG400 solutions. Infinite dilution values these parameters, o , obtained from their plots a function molality by extrapolation have been utilized obtaining transfer infinite dilution. All found to increase with increasing PEG400. Apparent isobaric expansions derived the temperature dependence finite concentrations. interpreted terms solute (diglycine or triglycine) co-solute solvent (H 2 O) interactions.
