摘要：

Precise density rho and viscosity eta data at 15, 25 and 35-degrees-C for solutions of glycine, DL-alanine, L-threonine, beta-alanine, gamma-aminobutyric acid and epsilon-aminocaproic acid in water and in (1m, 3m, 5m) aqueous potassium thiocyanate were measured and the limiting apparent molar volumes V(phi)-degrees and the B-coefficients calculated. The V(phi)-degrees and B values were split into the contributions from the NH3+,COO- and CH2 groups. These data are rationalized on the basis of hydrophillic and hydrophobic interactions between the various groups present in these solutions.
