Abstract
"RECUPERAçãO DE áCIDOS ORGáNICOS". Trata de um método de recuperação de um ácido orgânico a partir de uma solução salina diluída que inclui um sal de ácido orgânico. O cátion do sal forma um sal carbonato insolúvel. O método inclui a introdução de uma amina terciária e dióxido de carbono na solução de sal diluído para formar um complexo de ácido/amina, bem como o sal carbonato insolúvel. Um solvente imiscível em água é introduzido na solução de sal diluído para gerar uma fase de reação que inclui o complexo de ácido/amina e o solvente imiscível em água. O método inclui ainda secagem contínua da fase de reação e a formação de um produto entre o ácido e o solvente imiscível em água.
