Abstract

LOS FENOLES Y COMPUESTOS AROMATICOS RELACIONADOS, COMO ETERES FENOLICOS PUEDEN SER HIDROXILADOS DE FORMA SELECTIVA UTILIZANDO PEROXIDO DE HIDROGENO EN PRESENCIA DE UN CATALIZADOR FOSFATO DE CIRCONIO MICROCRISTALINO O AMORFO EN UN DISOLVENTE QUE CONTENGA UN ACIDO CARBOXILICO ALIFATICO. EL PROCESO ES PARTICULARMENTE APROPIADO PARA EL PROPIO FENOL Y EMPLEA VENTAJOSAMENTE UN CATALIZADOR MICROCRISTALINO PARCIALMENTE DESHIDRATADO OBTENIDO AL CALENTAR UN FOSFATO DE CIRCONIO MICROCRISTALINO HIDRATADO, POR EJEMPLO A 100 C. UNA TEMPERATURA DE REACCION CONVENIENTE ES DE 50 A 90 C Y UN DISOLVENTE APROPIADO ES EL ACIDO ACETICO. UN METODO MEJORADO PARA PRODUCIR EL CATALIZADOR ES EL DE PRECIPITAR EL FOSFATO DE CIRCONIO A PARTIR DE UNA DISOLUCION ACIDA FOSFORICA DE CLORURO DE CIRCONIO EN PRESENCIA DE UN AGENTE PORTADOR DE FASE CATIONICA COMO UNA SAL ALQUILPIRIDINIO O SAL AMONIO TETRAALQUILCUATERNARIA O UN SURFACTANTE NO IONICO COMO UN ETOXILATO DE ALCOHOL.
