Abstract

La produccion de ácido tereftálico mediante la oxidacion de p-xileno, se realiza de tal manera que se maximiza la concentracion de oxígeno en la fase líquida a través del uso de oxígeno puro o gel puro, mientras que simultáneamente se minimiza la concentracion de alimentacion de hidrocarburo a través de una rápida dilucion con el contenido del reactor.
