Abstract

PREPARACION DE 1,1,1,2-TETRAFLUOROETANO (134A) MEDIANTE LA REACCION, EN LA FASE GASEOSA, DE TRICLOROETILENO CON 1,1,1-TRIFLUOROCLOROETANO (133A) Y ACIDO HIDROFLUORICO EN PROPORCIONES MOLARES DE TRICLOROETILENO/133A QUE VAN DE 5/95 A 50/50 CON PRESENCIA DE UN CATALIZADOR QUE CONSTE DE CR2O3 CON SOPORTE EN AIF3. EL PROCESO DA COMO RESULTADO GRANDES CANTIDADES DE 134A EN MAS DE UN 90%, ADEMAS DE UNA DURACION EXCEPCIONALMENTE LARGA DEL CATALIZADOR. ASI, ES POSIBLE REALIZAR UN PROCESO CONTINUO MEDIANTE EL RECICLAJE DEL TRICLOROETILENO SIN REACCIONAR Y 133A, COMPENSANDO DE ESTE MODO LA CONVERSION TOTAL RELATIVAMENTE BAJA DE LOS REAGENTES.
