Abstract

PROCEDIMIENTO DE OBTENCION DE FENOLES. CONSISTE EN OXIDAR UN ACIDO BENZOICO -SUSTITUIDO O NO- EN FASE DE GAS Y EN PRESENCIA DE UN CATALIZADOR QUE CONTIENE COBRE. DICHO CATALIZADOR CONSISTE AL MENOS EN COBRE, Y/O UNO O MAS COMPUESTOS DE COBRE, VANADIO Y/O UNO O MAS COMPUESTOS DE VANADIO Y/O PLATA, LITIO, SODIO, MAGNESIO. LA TEMPERATURA DE REACCION ESTA COMPRENDIDA ENTRE 450 Y 700ºC Y LA PRESION OSCILA ENTRE 50 Y 2000 KPA. DICHA OXIDACION TIENE LUGAR EN FASE GAS EN UN REACTOR DE LECHO FLUIDO EN EL QUE SE INTRODUCE EL ACIDO BENZOICO SEPARADAMENTE DEL SUMINISTRO DE GAS QUE CONTIENE OXIGENO A UNA ALTURA ENTRE 1/4 Y 3/4 PARTES DE LA TOTAL DEL LECHO.
