FIELD: technology of recovery of ethyl acetate from reaction mixtures. SUBSTANCE: regeneration of ethyl acetate comprises carrying out reaction-rectification process of reacting acetic anhydride with mixture to be regenerated in rectification column. Acetic anhydride is directed to column top, distillate being pure ethyl acetate, and acetic acid is withdrawn as stillage product. Pure ethyl acetate is recovered from complex azeotropic mixture of ether, alcohol, acid and water. EFFECT: more efficient recovery method. 1 dwg, 3 ex
