Abstract

resumo patente de invenção: "extração por destilação de álcool bruto". a presente invenção refere-se à recuperação de etanol de um produto etanol bruto obtido pela hidrogenação de ácido acético, usando uma coluna de destilação com extração. a coluna fornece um primeiro resíduo que compreende etanol, acetato de etila, ácido acético e água. o primeiro resíduo é separado na segunda coluna para fornecer um segundo destilado que compreende etanol e acetato de etila. o segundo destilado é então separado na terceira coluna para fornecer um terceiro destilado que compreende acetato de etila e um terceiro resíduo que compreende etanol.
