Abstract

New equations describing the thermodynamic properties of the glycine + H₂O system are obtained from previously published measurements. The measured values span a range of temperatures of approximately 273 to 473 K for glycine(aq) and (5 to 310) K for α-glycine(cr). This work provides critically assessed values for the following properties: (1) thermal properties of α-glycine(cr) from 0 to 310 K, (2) the change in excess Gibbs energy for glycine(aq) solutions as a function of temperature, pressure, and molality, valid from 273 to 473 K, pressures up to 40 MPa, and the molality range of 0 to 3.6 mol kg^-1 (or the saturation limit), and (3) standard-state properties for the aqueous solution process.
