Abstract

PROCEDIMIENTO EN ESTADO VAPOR PARA PREPARAR DIESTERES DE ACIDO OXALICO. CONSTA DE LAS SIGUIENTES OPERACIONES: 1<002> PONER EN CONTACTO OXIDO DE NITROGENO Y UN ALCOHOL ALIFATICO MONOHIDRICO SATURADO EN ESTADO DE VAPOR A UNA TEMPERATURA DE 10 A 300<024>C DURANTE EL TIEMPO SUFICIENTE PARA FORMAR UN ESTER DE ACIDO NITROSO. 2<002> MANTENER EL ESTER DE ACIDO NITROSO EN ESTADO VAPOR Y PONER EN CONTACTO DICHO ESTER, LIBRE DE AGUA, CON MONOXIDO DE CARBONO EN ESTADO VAPOR, EN UNA ZONA DE REACCION FORMADORA DE OXALATO, A UNA TEMPERATUR DE 50 A 200<025>C, SOBRE UN CATALIZADOR SOPORTADO DE PALADIO QUE CONTIENE PALADIO METALICO O UNA SAL DEL MISMO; EL DIESTER DE ACIDO OXALICO OBTENIDO, SE RECUPERA LA ZONA FORMADORA DE OXALATO. EL ALCOHOL EMPLEADO ES METANOL O ETANOL. EN LA REACCION ESTA PRESENTE UN DILUYENTE INERTE GASEOSO TAL COMO NITROGENO, DIOXIDO DE CARBONO; Y MEZCLAS DE LOS MISMOS. EL SOPORTE DE CATALIZADOR EMPLEADO ES ALFA-ALUMINA.
