Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ETANOS PARCIALMENTE FLUORADOS DE ALTA PUREZA, QUE CORRESPONDEN A LA FORMULA CF3-CHXY, DONDE X ES HIDROGENO, FUOR, CLORO, BROMO O YODO. CONSISTE EN HACER REACCIONAR UN COMPUESTO DE ETILENO DE FORMULA CF2=CXY CON UNA CANTIDAD EQUIMOLECULAR DE FLUORURO DE HIDROGENO EN FASE GASEOSA. LA REACCION SE LLEVA A CABO A UNA TEMPERATURA COMPRENDIDA ENTRE 20 Y 200 C. Y EN PRESENCIA DE UN CATALIZADOR DE OXIFLUORURO DE CROMO. DE APLICACION COMO ADITIVOS EN ANALGESICOS Y ANESTESICOS EN FORMA DE GAS, COMO MEDIOS INTERCAMBIADORES DE CALOR Y COMO COMPONENTES DE AGENTES EXPANSIVOS.
