Abstract

SE PRESENTA UN PROCEDIMIENTO PARA PRODUCIR DIFLUOROMETANO QUE INCLUYE EL PASO DE PONER EN CONTACTO UNA MEZCLA GASEOSA QUE CONTENGA CH{SUB,2}CL{SUB,2} Y FLUORURO DE HIDROGENO CON UN CATALIZADOR QUE CONTENGA UNA CANTIDAD CATALITICAMENTE EFECTIVA DE UN CROMO TRIVALENTE SOPORTADO SOBRE UN CARBONO QUE TENGA UN CONTENIDO DE CENIZAS INFERIOR AL 0.5% EN PESO, A UNA TEMPERATURA DE ENTRE 180 (GRADOS) Y 375 (GRADOS) C. EL CATALIZADOR Y LAS CONDICIONES DE TEMPERATURA DE ESTE PROCEDIMIENTO PERMITEN LA REACCION CONCURRENTE DE CCL{SUB,3}CF{SUB,3} CON HF PARA FORMAR CCL{SUB,2}FCF{SUB,3}. EL CH{SUB,2}CLF Y EL CH{SUB,2}CL{SUB,2} NO REACCIONADO, CADA UNO DE LOS CUALES PUEDE RECUPERARSE COMO UN AZEOTROPO CON FH, PUEDEN RECICLARSE.
