Abstract

LA INVENCION SE REFIERE A UN CATALIZADOR A BASE DE ELEMETOS MOLIBDENO, VANADIO, FOSFORO Y AXIGENO Y EN CASO DADO DE UNO O MAS IONES DE METALES COMO COMPONENTES ACTIVOS QUE ESTAN SITUADOS PREFERENTEMENTE SOBRE UN PORTADOR INERTE. SE CATALIZA LA DESHIDROGENACION OXIDATIVA DE ACIDO ISOBURITICO O DE SUS ESTERES SENCILLOS O ACIDOS METACRILICO O SUS ESTERES SENCILLOS. LA PARTE CATALITICAMENTE ACTIVA PUEDE SER UNA MEZCLA DE HETEROPOLIMOLIBDATO DE ACIDO FOSFORICO, MOLIBDENICO Y/O DE SUS DERIVADOS VANADICOS, EN CASO DADO PARCIALMENTE EN FORMA DE UNO O VARIOS DERIVADOS DE SALES DE METALES, EN ESPECIAL DEL DERIVADO DE COBRE, O SEA, DE ESTOS HETEROPOLIACIDOS. ESTOS CATALIZADORES DE LA OXIDEHIDROGENACION DE ACIDO ISOBURITICO O DE SUS ESTERES SE CARACTERIZAN, COMPARADOS CON LOS CATALIZADORES CONOCIDOS BASE DE HETEROPOLIACIDOS POR SU MEJOR COMPORTAMIENTO A LARGO TIEMPO.
