Abstract

ALGUNOS COMPUESTOS AROMATICOS, COMO EL BENCENO, TOLUENO Y XYLENO SE HIDROXILAN POR REACCION CON OXIGENO E HIDROQUINONA O UNA HIDROQUINONA SUSTITUIDA EN PRESENCIA DE UN COMPUESTO DE VANADIO, TIPICAMENTE UN OXI-QUELATO DE VANADIO PENTAVALENTE, CON ACIDO PICOLINICO O UN ACIDO PICOLINICO SUSTITUIDO. EL COMPUESTO DE VANADIO PUEDE PRODUCIRSE IN SITU POR REACCION DEL AGENTE QUELADOR CON UN COMPUESTO DE VANADIO PRECURSOR, TETRAVALENTE O PENTAVALENTE.
