Xl. Ren et al., APPARENT MOLAR VOLUMES OF L-GLYCINE, L-ALANINE, AND L-SERINE IN WATERPLUS DIMETHYLFORMAMIDE MIXTURES AT 298.15 K, Journal of chemical and engineering data, 43(5), 1998, pp. 700-702
Densities of L-glycine, L-alanine, and L-serine have been measured wit
h an oscillating-tube densimeter at 298.15 K in water + dimethylformam
ide (DMF) mixtures ranging from pure water to 45% DMF by mass. From th
ese densities, apparent molar volumes and limiting apparent molar volu
mes of the three amino acids in the mixtures have been calculated. Tra
nsfer volumes were interpreted in terms of the structure-making or str
ucture-breaking effects of these amino acids in the mixtures.
