Abstract
LOS SISTEMAS CATALIZADORES QUE CONTIENEN UN CATALIZADOR DE METAL DEL GRUPO DEL PLATINO, UN COCATALIZADOR, UNA SAL CUATERNARIA Y UNA BASE PARA LA CARBONILACION OXIDATIVA DE HIDROXICOMPUESTOS AROMATICOS PARA FORMAR LOS CORRESPONDIENTES DIARILCARBONATOS SON RECUPERADOS, SEGUN LA INVENCION, MEDIANTE CRISTALIZACION POR FUSION, COMO RESIDUO FUNDIDO, PUDIENDO SER NUEVAMENTE LLEVADOS A LA REACCION DE CARBONILACION O TRANSFORMADOS EN SUSTANCIAS DE VALOR. EL MATERIAL CRISTALIZADO POR FUSION, QUE ESTA COMPUESTO BASICAMENTE POR DIARILCARBONATO Y EL HIDROXICOMPUESTO AROMATICO DE BASE, SE TRANSFORMA EN UN DIARILCARBONATO PURO Y EN UN HIDROXICOMPUESTO PURO.
