Abstract

processo para recuperar um catalisador ácido a partir de ácido glicólico aquoso. é exposto um processo para a recuperação extrativa de um catalisador ácido a partir de uma mistura aquosa de ácido glicólico com um solvente de extração, que compreende uma amina terciária ou um composto de carboxilato de ônio, um modificador, e um diluente. o catalisador ácido, que pode compreender ácido fortes, tais que o ácido sulfúrico, ácido alquil sulfônicos, e ácidos fluroalquil sulfônicos, pode ser recuperado através de retroextração com formaldeído aquoso e reciclado a uma processo para a preparção do ácido glicólico através de carbonilação catalisada por ácido de formaldeído.
