Abstract

Patente de Invenção: "PROCESSO PARA PURIFICAçãO DEALCANOATO DE ALQUILA". Processo é descrito para arecuperação de alcanoato de alquila substancialmente puro, talcomo acetato de etila de uma matéria-prima de alimentação impura.A matéria-prima de alimentação impura é contatada com umcatalisador de hidrogenação seletivo na presença de hidrogênioem uma zona de hidrogenação seletiva mantida sob condições dehidrogenação seletiva para hidrogenação seletiva de impurezascontendo grupos carbonila reativos desse modo para hidrogenarditas impurezas aos álcoois correspondentes. Após recuperaçãoda zona de hidrogenação seletiva de uma mistura do produto dereação seletivamente hidrogenado compreendendo dito alcanoatode alquila e ditos álcoois correspondentes esta é destilada em umaou mais zonas de destilação a fim de produzir alcanoato de alquilasubstancialmente puro o qual é recuperado.
