Abstract

PROCESSO PARA PRODUZIR UMA MISTURA DE áCIDO CARBOXìLICO/DIOL, E DE áCIDO TEREFTáLICO/DIOL A presente invenção refere-se a um processo, pelo qual uma mistura de ácido carboxílico/diol é obtida a partir de um produto de ácido carboxílico em suspensão ou torta, sem isolamento de um sólido de ácido carboxílico substancialmente seco. De modo mais específico, a presente invenção refere-se a um processo, pelo qual uma mistura de ácido tereftálico/etileno glicol, adequada como um material de partida para a produção de poliéster ou copoliéster é obtida a partir de um produto de ácido tereftálico em suspensão ou torta, sem o isolamento de um sólido de ácido tereftálico substancialmente seco.
