Abstract

UN PROCEDIMIENTO PARA LA PREPARACION DE UNO O MAS DE CHCIFCF{SUB,3} (HCFC-124), CHF{SUB,2}CCIF{SUB,2}(HCFC-124A) Y CHF{SUB,2}CF{SUB,3} (HFC-125), MEDIANTE REACCION DE PERCLOROETILENO CON FLUORURO DE HIDROGENO EN UN RECIPIENTE DE REACCION DE ETAPA UNICA, EN PRESENCIA DE UN CATALIZADOR DE FLUORACION. ESTOS COMPUESTOS SON UTILES EN DIFERENTES APLICACIONES INDUSTRIALES, QUE INCLUYEN AGENTES SOPLANTES, REFRIGERANTES, GASES ESTERILIZANTES, Y APLICACION COMO DISOLVENTES. LA DESTILACION DEL PRODUCTO DE REACCION PRODUCE UN DESTILADO QUE COMPRENDE HCL, CHCIFCF{SUB,3}, CHF{SUB,2}CCIF{SUB,2} Y CHF{SUB,2}CF{SUB,3}, Y UNA MINIMA CANTIDAD DE HF, CUYO DESTILADO SE PURIFICA PARA ELIMINAR LOS ACIDOS. EL PRODUCTO RESIDUAL COMPRENDE PERCLOROETILENO, FLUORURO DE HIDROGENO, Y SUBPRODUCTOS ORGANICOS, QUE SE SEPARAN EN FASE PARA SECUESTRAR EL FLUORURO DE HIDROGENO PRESENTE EN LA MEZCLA DE PERCLOROETILENO Y SUBPRODUCTOS ORGANICOS. EL FLUORURO DE HIDROGENO, Y LA MEZCLA DE PERCLOROETILENO CON SUBPRODUCTOS ORGANICOS,SON A CONTINUACION PREFERIBLEMENTE REMEZCLADOS A VELOCIDAD REGULADA, Y RECICLADOS AL RECIPIENTE DE REACCION.
