Abstract
FIELD: separation and purification of ethanol. SUBSTANCE: method for separation and purification of synthetic ethanol includes fractionation of initial crude alcohol with the use of hydraulic selection at the total mass ratio of water and alcohol of (6-16):1. In so doing, crude alcohol is introduced into fractionating column in the point corresponding to the number of theoretical trays under the feed tray of at least 15. EFFECT: higher efficiency.
