Partial molar isentropic pressure coefficients of some N-acetyl amino acid and peptide amides at infinite dilution in aqueous solutions at the temperature 298.15 K
The partial molar isentropic pressure coefficients at infinite dilution k ∞ S,2 = −(∂ V∞/∂ p) S , where V ∞ 2is the partial molar volume at infinite dilution, have been determined for six N-acetyl amino acid and peptide amides in aqueous solution at the temperature 298.15 K. The results obtained hav...
