Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE ACILACION DE UN ETER AROMATICO. LA INVENCION SE REFIERE PREFERENTEMENTE A UN PROCEDIMIENTO DE ACILACION DE UN ESTER AROMATICO SUSTITUIDO Y MAS EN PARTICULAR VERATROL. EL PROCEDIMIENTO DE ACILACION QUE CONSISTE EN HACER REACCIONAR DICHO ETER CON UN AGENTE DE ACILACION, EN PRESENCIA DE UN CATALIZADOR ZEOLITICO, SE CARACTERIZA POR EL HECHO DE QUE SE CONDUCE LA REACCION DE ACILACION EN PRESENCIA DE UNA CANTIDAD EFICAZ DE UN CATALIZADOR QUE COMPRENDE UNA ZEOLITA DE TIPO FAUJASITA O ZEOLITA Y QUE TIENE LAS SIGUIENTES CARACTERISTICAS FISICOQUIMICAS: UNA RELACION ATOMICA LLAMADA "SI/ME{SUP,1} GLOBAL", ENTRE EL NUMERO DE ATOMOS DEL ELEMENTO SILICIO Y EL NUMERO DE ATOMOS DE CUALQUIER ELEMENTO TRIVALENTE ME{SUP,1} CONTENIDO EN LA ZEOLITA, COMPRENDIDO ENTRE 2,4 Y 90, PREFERENTEMENTE ENTRE 2,4 Y 75 Y DE MANERA AUN MAS PREFERENTE, ENTRE 2,4 Y 60; UN CONTENIDO EN METAL ALCALINO ME{SUP,2} DE MANERA QUE LA RELACION ATOMICA ME{SUP,2}/ME{SUP,1(IV, ENTREEL NUMERO DE ATOMOS DE METAL ALCALINO ME{SUP,2} Y EL NUMERO DE ATOMOS DE CUALQUIER ELEMENTO TRIVALENTE ME{SUP,1(IV INCLUIDO EN LA RED ZEOLITICA, ES INFERIOR A 0,2, PREFERENTEMENTE INFERIOR A 0,1 Y DE MANERA AUN MAS PREFERENTE, INFERIOR A 0,05.
