Abstract
SE PRESENTA UN PROCESO PARA HIDROFLUORAR ADIABATICAMENTE HIDROCLOROCARBONOS E HIDROCLOROFLUOROCARBONOS EN LA FASE GASEOSA EN LA PRESENCIA DE UN CATALIZADOR QUE ES ACTIVO A LA TEMPERATURA INICIAL DE REACCION Y PERMANECE ALTAMENTE SELECTIVO A LA TEMPERATURA DE REACCION MAXIMA, POR EJEMPLO UN CATALIZADOR DE CR. LA PROPORCION MOLAR DE HF CON RESPECTO A LOS COMPUESTOS DE INICIO ES DE AL MENOS 2.5:1. LA TEMPERATURA DE REACCION INICIAL SE SELECCIONA DE MANERA QUE EL HF EN LA CORRIENTE DE SUMINISTRO ESTE PARCIALMENTE ASOCIADO PERO NO COMPLETAMENTE (HF){SUB,6}. EL CATALIZADOR PUEDE ESTAR SOPORTADO O NO SOPORTADO.
