Abstract

"PROCESSO PARA PRODUZIR UM ALQUIL éSTER DE UM áCIDO CARBOXìLICO". A presente invenção diz respeito a um processo para produzir um alquil éster de um ácido carboxílico através de transesterificação compreendendo as etapas de: (1) reagir um éster de ácido carboxílico com um álcool e uma quantidade eficaz de um catalisador de transesterificação em uma zona de reação para formar uma mistura de reação compreendida de um éster produto e um álcool produto; (2) passar a mistura de reação da etapa (1) por uma zona de separação centrífuga em que o segundo álcool é separado do segundo éster. O processo de acordo com a invenção permite tempos de reação mais curtos e rendimentos melhorados do produto.
