Abstract

Se divulga un proceso y aparato optimizados para llevar a cabo más eficiente y económicamente la oxidación en fase liquida de un compuesto oxidable. Tal oxidación en fase líquida se lleva a cabo en un reactor de columna de burbujeo que proporciona una reacción altamente eficiente a temperaturas relativamente bajas. Cuando el compuesto oxidado es para-xileno y el producto de la reacción de oxidación es ácido tereftálico crudo (CTA), tal producto de CTA se puede purificar y separar mediante técnicas más económicas que podrían ser empleadas si el CTA se formara por un proceso de oxidación de alta temperatura convencional.
