Abstract
PROCESSO PARA OBTENÇÃO DE UM ÉSTER DE ÁCIDO CARBOXÍLICO E DISPOSITIVO PARA A REALIZAÇÃO DO PROCESSO A presente invenção diz respeito a um processo para obtenção de um éster de ácido carboxílico, em especial um éster de ácido acético e mais particularmente acetato de etila. A presente invenção diz respeito mais particularmente a um processo de obtenção de um éster de ácido carboxílico a partir de uma fase orgânica resultante de uma reação de esterificação entre um ácido carboxílico e um álcool, a dita fase orgânica consistindo pelo menos em maior quantidade de éster de ácido carboxílico e em menos quantidade de álcool e de água, caracterizado pelo fato de compreender uma etapa de separação ao longo da qual a fase orgânica é empobrecida em álcool e separada do ácido carboxílico pro meio de uma operação de extração líquido/líquido ao pôr em contacto a dita fase orgânica com uma fase aquosa para extrair o álcool e o ácido carboxílico presente na fase orgânica para a fase aquosa.
