ABSTRACT
A new set of vapor pressure data for the aqueous solutions of Ethaline, Glyceline, Maline, and Reline at different temperatures (30, 40, 50, 60, 70 deg C) and concentrations (20, 40, 60, 80 wt%) are presented. The data successfully fit the classic Antoine equation, for the temperature-dependence of the vapor pressure, and a Volger-Tamman-Fulcher-type equation, for the concentration-dependence of the vapor pressure. The % AADs for the experimental and calculated data were all less than 0.5 %.
