Abstract

UN PROCEDIMIENTO PARA LA MANUFACTURA DE 1, 1-DICLOROTETRAFLUORETANO, CF3CCL2F (CFC-114A), SUBSTANCIALMENTE LIBRE DE 1, 2-DICLOROTETRAFLUORETANO, CCLF2CCLF2 (CFC 114), Y PRODUCTOS SOBRE-FLUORADOS (POR EJEMPLO, CF2CCLF2 Y CF3CF3) QUE COMPRENDE LAS ETAPAS DE PONER EN CONTACTO UNA FASE LIQUIDA DE TRICLOROTRIFLUORETANO ¡ES DECIR UNA MEZCLA DE 1, 1, 1- TRICLOROTRIFLUORETEANO, CCL3CF3 (CFC-113A) Y 1, 1, 2-TRICLOROTRIFLUORETANO, CCLF2CCL2F (CFC-113)¿ CON UN CATALIZADOR DE PENTAHALURO DE ANTIMONIO (POR EJEMPLO, CBC) (5-X)F(X), DONDE X ES 0 A 3 Y SEPARAR UN PRODUCTO DE 1, 1- DICLOROTETRAFLUORETANO GASEOSO. SE LOGRO EN UN PROCEDIMIENTO CONTINUO UNA CONVERSION CASI CUANTITATIVA DE CF3CCL3 A CF3CCL2F, SIN PRODUCCION PERCEPTIBLE DE CCLF2CCLF2. EL CF3CCL2F ES UTIL COMO INTERMEDIARIO EN LA MANUFACTURA DE HIDROCLOROFLUORCARBUROS E HIDROFLUORCARBUROS.
