Název v původním jazyce

Partial molar volumes of organic solutes in water. XX. Glycine(aq) and L-alanine(aq) at temperatures T = 298 K to 443 K and at pressures up to 30 MPa.

Popis výsledku v původním jazyce

Density data for dilute aqueous solutions of two amino acids (glycine, L-alanine) obtained using a flow vibrating-tube densimeter are presented together with partial molar volumes at infinite dilution (standard molar volumes, V0m,2) calculated from the measured data. The experiments were performed at temperatures from T = 298 K up to T = 443 K at pressures close to the saturation line of water, at pressures in the range from 15 MPa to 17 MPa, and at 30 MPa. Values of an analogue of isothermal compressibility, ?0T,2 = -(1/V0m,2)(V0m,2/p)T, are also evaluated. Maxima on the curves V0m,2(T) and ?0T,2(T) are observed and discussed. The new data along with literature values of standard molar volumes and heat capacities are used for generating the recommended parameterization of an equation of state for standard molar thermodynamic properties of the aqueous amino acids.
