Abstract
FIELD: chemical technology. SUBSTANCE: method of ethanol refining from acetic acid, crotonic and valeric aldehydes impurity involves rectification in the presence of alkali. The obtained distillate - alcohol and alkaline vat product is recovered in fractionating column. Process is carried out in the presence of 1-5 weight % alkali solution in C-C-alcohol or their mixture at the weight ratio parent ethanol : alkali solution in C-C-alcohol or their mixture = 1:(0.3-0.5). EFFECT: increased purity of the end product.
