Abstract

"PROCESSO PARA PRODUçãO DE éSTER DE áCIDO CARBOXìLICO ALIFáTICO INFERIOR". A presente invenção refere-se a um processo para produção de um éster de ácido carboxílico alifático inferior através de uma reação de esterificação em fase gasosa partindo de um ácido carboxílico alifático inferior e de uma olefina inferior, processo este que compreende adicionar um álcool inferior correspondente a um hidrato de uma olefina inferior ao produto de reação em fase gasosa, condensação de um ácido carboxílico alifático inferior e do álcool inferior e, enquanto se permite continuar a conversão em um éster de ácido carboxílico alifático inferior, separar o éster de ácido carboxílico alifático inferior. A produtividade é aumentada devido ao aperfeiçoamento da conversão de um ácido carboxílico alifático inferior.
