摘要:
The apparent molar volumes of DL–α–alanine, DL–β–alanine, DL–α–aminobutyric acid, DL–α–phenylalanine, DL–serine and DL–aspartic acid in very dilute aqueous solutions at 25,00°C were determined from density measurements. From these data it is shown that the concentration dependence of the apparent molar volume of these amino acids at very low molality differs from the behavior found at concentrations higher than 0,01m. This change has been attributed to solute-water interactions which prevail at very high dilution.
