Abstract

PROCEDIMIENTO HETEROGENEO EN FASE VAPOR PARA PREPARAR UN DIESTER DE ACIDO OXALICO. CONSISTE EN HACER REACCIONAR UN ESTER DE ACIDO NITROSO EN ESTADO VAPOR CON MONOXIDO DE CARBONO EN ESTADO DE VAPOR Y EN PRESENCIA DE UN CATALIZADOR SOPORTADO DE PALADIO SOLIDO CONSISTENTE EN PALADIO METALICO O UNA SAL DEL MISMO DEPOSITADO SOBRE UN SOPORTE NO ACIDO CON UN AREA SUPERFICIAL INFERIOR A 10 M /G, A UNA TEMPERATURA DE 50 A 200<025>C. EL ESTER DE ACIDO NITROSO, SE FORMA POR REACCION CON UN ALCOHOL MONOHIDRICO ALIFATICO SATURADO Y RECUPERANDOSE EL DIESTER DE ACIDO OXALICO, DONDE EL GRUPO ESTER CORRESPONDE AL ALCOHOL FORMADO EN LA PRODUCCION DEL ESTER DE ACIDO NITROSO. EL SOPORTE EMPLEADO ES UNA ALFA-ALUMINA CON UN AREA SUPERFICIAL COMPRENDIDA ENTRE 0,001 Y 10 M /G. LA PRESION EMPLEADA VA DE 1 A 7 ATMOSFERAS. EL TAMAÑO DE PARTICULA DEL PALADIO ES INFERIOR A 10.000 ANGSTROMS.
