Abstract
Un proceso para la fabricación de un ácido carboxílico o su éster por oxidación catalítica en fase líquida de un precursor correspondiente usando ácido acético como solvente, que comprende: (i) formar un medio de reacción que comprende ácido acético, catalizador de oxidación, precursor, y oxidante; (ii) en forma opcional reciclar el acetato de metilo, producido como subproducto a partir del ácido acético, nuevamente al medio de reacción; (iii) introducir al medio de reacción acetato de metilo adicional y/o metanol, dicho acetato de metilo adicional a cualquier acetato de metilo recuperado reciclado al medio de reacción. Reivindicación 2: Un proceso de acuerdo con la reivindicación 1, caracterizado porque el ácido carboxílico es ácido tereftálico y su precursor es p-xileno.
