Abstract

LA INVENCION SE REFIERE A UN PROCESO CONTINUO DE FABRICACION DEL 1,1,1,2-TETRAFLUOROETANO (134A) A PARTIR DE 2-CLORO-1,1,1TRIFLUOROETANO (133A) Y DE ACIDO FLUORHIDRICO EN FASE GASEOSA EN PRESENCIA DE UN CATALIZADO R A BASE DE CROMO. SEGUN LA INVENCION SE SOMETE EL FLUJO GASEOSO QUE SALE DEL REACTOR A UNA DESTILACION PARA SEPARAR EN CABEZA UN FLUJO QUE CONTIENE LA CASI TOTALIDAD DEL HCI Y AL MENOS 90% DEL 134A PRODUCIDOS POR LA REACCION Y EN PIE UN FLUJO QUE CONTIENE AL MENOS 90% DE LOS REACTIVOS NO TRANSFORMADOS (133A Y HF) Y SE RECICLA EL ULTIMO FLUJO DIRECTAMENTE EN EL REACTOR, SIN NINGUNA OPERACION DE PURIFICACION.
