Abstract

SE EXPONE UN PROCESO PARA PRODUCIR CONTINUAMENTE UN ACIDO CARBOXILICO AROMATICO, QUE COMPRENDE OXIDAR UN COMPUESTO AROMATICO, SUSTITUIDO POR GRUPOS ALQUILO, CON GAS OXIGENO MOLECULAR EN LA FASE LIQUIDA, EN UN DISOLVENTE QUE CONTIENE UN ACIDO CARBOXILICO ALIFATICO INFERIOR, EN PRESENCIA DE UN CATALIZADOR QUE COMPRENDE COMPUESTOS DE METALES PESADOS Y UN COMPUESTO DE BROMO, CARACTERIZADO PORQUE UN LIQUIDO DE CRISTALIZACION, QUE SE OBTIENE DESPUES DE RETIRADA DE LOS CRISTALES DE UN LIQUIDO DE REACCION DE LA OXIDACION EN FASE LIQUIDA Y CONTIENE IONES DE METALES PESADOS, Y EL ION BROMO COMO COMPONENTES CATALIZADORES, SE PONEN EN CONTACTO CON UNA RESINA DE QUELATO DEL TIPO DE INTERCAMBIO DE ANIONES PARA RECUPERAR LOS COMPONENTES DEL CATALIZADOR. LOS COMPONENTES DEL CATALIZADOR SE RECUPERAN EFICIENTEMENTE, POR LO QUE NO SE NECESITAN AGENTES AUXILIARES EN CANTIDAD EXCESIVA A LA EQUIVALENTE, NI TAMPOCO UN EXCESO DE TRABAJO.
