FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing ethyl acetate by esterification of acetic acid, wherein alcohol production waste is used, containing C3-C5 alcohols at a concentration of at least 3,300 mg/dm3 (0.4 wt.%), allowing for a reduction in the lowest required amount of phlegm supplied to the reactor to collect all the water formed in the form of azeotrope. The purpose of the invention consists in developing an effective method for producing ethyl acetate from watered alcohol production waste.
EFFECT: claimed method allows for execution of the process with lower recirculation of esters as phlegm and an azeotropic agent, reducing the load on the rectification part of the apparatus, as well as the systems for heat supply and cooling of products discharged from the column.
