Freezing and Eutectic Points of an Aqueous Amino Acid Solution Containing Ethanol, and the Effect of Ethanol Addition on the Freeze Concentration Process

Temperature Dependence of Solubility Predicted from Thermodynamic Data Measured at a Single Temperature: Application to α, β, and γ-Glycine

“…Expected eutectic temperatures and freezing curve The open black symbols are freezing curve measurements, − and the gray dashed line is the best fit line. The solid lines are the estimated eutectic temperature, and the opaque bands indicate the uncertainty.…”

“…Eutectic temperature and composition predictions α-, β-, and γ-glycine based on eq , with coefficients derived from different glycine–water solution models. Open circles are freezing point measurements for water, − and the gray dashed line is the best-fit line. Blue refers to α-, red refers to β-, and gray refers to γ-glycine.…”

“…The dashed lines is the prediction of the Scatchard–Hildebrand model, and the solid lines Scatchard–Hildebrand–Flory–Huggins model. The open symbols are ratios derived from direct measurements − (see Supporting Information), and the pluses are estimates from free energy ratios, stars are estimates from eutectic temperatures and freezing point data, triangles are estimates from ref , and gray squares are α–γ crossover estimates. ,,− Bars indicate uncertainty estimates.…”
