Abstract

UN PROCESO PARA PRODUCIR ACIDO 2,6 - NAFTALENDICARBOXILICO QUE INCLUYE OXIDAR 2,6 - DIMETILNAFTALENO CON UN GAS QUE CONTIENE OXIGENO EN UN SOLVENTE QUE INCLUYE UN ACIDO CARBOXILICO ALIFATICO DE CADENA CORTA EN PRESENCIA DE UN CATALIZADOR QUE INCLUYE COBALTO, MANGANESO, Y BROMO, DONDE LA CANTIDAD TOTAL DE COBALTO Y MANGANESO EN EL CATALIZADOR ES DE ENTRE 50 Y 300 MG ATOMO POR 1 G MOL DE 2,6 - DIMETILNAFTALENO, LA RELACION POR G ATOMO DE MANGANESO A COBALTO EN EL CATALIZADOR ES DE ENTRE 20:1 Y 4:1, Y LA OXIDACION SE LLEVA A CABO A UNA TEMPERATURA DE ENTRE 200 Y 250 (GRADOS) C; Y UN PROCESO COMO SE DESCRIBIO ANTERIORMENTE, DONDE UN LICOR MADRE OBTENIDO DE UNA LECHADA DE UN PRODUCTO DE LA OXIDACION VIA UN PASO DE SEPARACION SOLIDO-LIQUIDO SE RECICLA A UN PASO DE OXIDACION TRAS TRATAMIENTO TERMICO A UNA TEMPERATURA DE 150 (GRADOS) C O SUPERIOR. DE ACUERDO CON LOS PROCESOS, SE PREVIENE LA ACUMULACION DE SUSTANCIAS QUE AFECTAN ADVERSAMENTE A LA OXIDACION. MAS AUN, ES POSIBLE RECICLAR UNA GRAN FRACCION DE UN LICOR MADRE DE OXIDACION SIN DISMINUIR EL RENDIMIENTO DE LA REACCION, Y ES POSIBLE UTILIZAR CON EFICACIA LOS COMPONENTES CATALIZADOR Y LOS COMPONENTES SOLVENTE DEL LICOR MADRE DE OXIDACION.
