Abstract

UN PROCESO Y NUEVO CATALIZADOR PARA LA CARBONILACION DE UNO O MAS ALCOHOLES, ETERES Y ETER ALCOHOLES A ESTERES Y, OPCIONALMENTE, A ACIDOS CARBOXILICOS. LA REACCION SE EFECTUA EN ESTADO DE VAPOR SOBRE CATALIZADOR SOLIDO COMPRENDIENDO UN ANION DE POLIOXOMETALATO EN EL CUAL EL METAL TIENE AL MENOS UNO TOMADO DE LOS GRUPOS V Y VI DEL CUADRO PERIODICO DE ELEMENTOS ASOCIADO A UN CATION DE UN MIEMBRO DEL GRUPO VIIIA DEL CUADRO PERIODICO DE LOS ELEMENTOS. PREFERIBLEMENTE, EL CATALIZADOR ESTA DEPOSITADO SOBRE UN SOPORTE QUE ES INERTE A LA REACCION. EL SOPORTE PREFERIDO ES SILICE.
