A binary mixture of known composition (alcohol-hydrocarbon or alcohol-water) and total mass of about 10-15 g placed in thermostat was titrated by the third component from a calibrated microburette until permanent turbidity was formed. The both branches of solubility curve were in mutual agreement. The binodal curve at normal boiling point was measured in a modified Washburn's ebulliometer [1] until the first lasting turbidity by the titration method. Temperatures were recalculated to the pressure of 760 Torr. The International Union of Pure and Applied Chemistry Washburn, E. R.; Beguin, A. E.; J. Am. Chem.
