Methodology:
The standard titration method was used to construct the binodal curve. Refractive indexes and densities of points on the binodal curve were measured. Ternary mixtures of known composition were shaken in the thermostat for 1 h. After separation, refractive indexes and densities of both phases were measured and concentrations were calculated from calibration curves prepared during solubility measurements. The results of the analysis of the water-rich phase were checked for a few points by redistillation and further analysis of distillate by GLC and the Karl Fischer methods.
