Abstract

Se describe un reactor para la oxidacion de un precursor a un acido carboxilico aromatico o ester del mismo en una mezcla de reaccion en fase liquida. El reactor (1) comprende un recipiente alargado, sustancialmente vertical en el uso, que tiene un elemento de mezclado superior (5) y un elemento de mezclado inferior (3), caracterizado porque el elemento de mezclado superior (5) es un propulsor de bombeo axial, y el elemento de mezclado inferior (3) es un propulsor de bombeo radial. Se describe tambien un proceso para la produccion de un acido carboxilico o el ester del mismo, en un reactor de la invencion. En el uso, la configuracion de los elementos de mezclado conduce a tres zonas de mezclado altamente turbulentas. En una modalidad preferida del proceso de la presente invencion el oxidante, proveniente de una entrada, y el solvente, el precursor y el catalizador, son introducios directamente en una zona de mezclado. Las zonas de mezclado altamente turbulentas conducen a transferencia de masa rapida, suprimiendo la formacion de subproductos coloreados, no deseados, y ensuciamiento reducido del reactor.
