Abstract

''PROCESSO PARA A PRODUçãO DE éSTERES''. A presente invenção compreende um processo para produzir um éster compreendendo as etapas de: (a) alimentar a um primeiro vaso uma alimentação que compreende ácido orgânico, álcool, e água, a partir do que o ácido orgânico e o álcool reagem para formar éster monomérico e água, e a partir do que um primeiro efluente líquido é produzido compreendendo como seus componentes pelo menos algum éster, álcool, e água, os componentes do primeiro efluente líquido estando substancialmente em equilíbrio de reação; e (b) alimentar o primeiro efluente líquido a um segundo vaso, a partir do que são produzidas uma corrente de produto em vapor e uma segunda corrente de efluente líquido, compreendendo éster, álcool e água, sendo que o segundo vaso é mantido substancialmente em equilíbrio vapor-líquido mas não substancialmente em equilíbrio de reação.
