Determination of liquid-vapor equilibria in three-component ethanol-water-solvent systems showed that the highest degree of water removal from ethanol on one theoretical plate is achieved with the use of monoethylene glycol. The boiling points of ethanol-water-monoethylene glycol and ethanol-water-triethylene glycol three-component mixtures have been determined. The ethanol-water azeotrope is destroyed if the content of mono- or triethylene glycol is 25 mass % or more. With water contents from 0 to 60 mole % in ethanol the presence of separating agents increases the distribution ratio of water between the liquid and the vapor, while with water contents from 70 to 100 mole % the distribution ratio is lowered.
