Abstract

The invention relates to the production of alcohol, namely a process for the production of dehydrated ethyl alcohol.The process for the production of ethyl alcohol dehydrated to a concentration of 98.9…99.5 vol.% includes the distillation of the ethyl alcohol with a concentration of 95.5…96.5 vol.% in countercurrent with 1,2-propylene glycol in a ratio of 1:1, liquefaction of ethyl alcohol vapors and collection of dehydrated ethyl alcohol.As ethyl alcohol may also be used the tail fractions of the production of rectified grain and treacly ethyl alcohol, wine distillate and rectified grape ethyl alcohol, preconcentrated up to 95.5…96.5 vol.%.
