Abstract
Способ осушки этилового спирта экстрактивной ректификацией с использованием в качестве экстрагента моно-, ди-, триэтиленгликолей, отличающийся тем, что, с целью повышения степени осушки этилового спирта и упрощения процесса, в используемый экстрагент дополнительно вводят олигобораты моно-, ди-, триэтиленгликолей или их смесь, взятые в количестве 0,5 - 5 мас.% в пересчете на борную кислоту.The method of drying ethyl alcohol by extractive distillation using mono-, di-, triethylene glycols as an extractant, characterized in that, in order to increase the degree of drying of ethyl alcohol and simplify the process, oligoborates by mono-, di-, triethylene glycols or their the mixture, taken in an amount of 0.5 - 5 wt.% in terms of boric acid.
