Abstract

Process for the purification of ethanol, which had been obtained by catalytic hydration of ethylene by phosphoric acid contacts and obtained as dilute crude alcohol, by extractive distillation with water as extraction medium and by rectification characterized by the crude alcohol, approximately with a concentration of 10 to 15% it is loaded on top of a first washing column, while the spray water, taken at the bottom of a rectifier column, connected behind, widely freed of alcohol, having a ph value of 8 to 12, it is introduced in such a way in the upper part of the first column, that for a few or few funds below the place of entry of the crude product, it enters the column, in which the condensate obtained from the vapors detached from the first washing column, is fully or partially loaded on a second washing machine, while the residual residual condensate is returned to the washing machine. On the first washing machine column. (Machine-translation by Google Translate, not legally binding)
