Abstract

SE PRESENTA UN PROCESO PARA PREPARAR PERFLUOROPOLIETERES PEROXIDICOS POR OXIDACION DE UN TETRAFLUOROETILENO CON OXIGENO, EN FASE LIQUIDA QUE COMPRENDA UN SOLVENTE Y EN LA PRESENCIA DE UN INICIADOR QUIMICO A UNA PRESION ENTRE 2 Y 15 ATMOSFERAS ABSOLUTAS Y OPERANDO CON UNA PROPORCION MOLAR DE TETRAFLUOROETILENO CON RESPECTO AL INICIADOR QUIMICO MAYOR DE 35. EL PROCESO PERMITE INCREMENTAR EL PESO MOLECULAR DE LOS PERFLUOROPOLIETERES CON EL MISMO CONTENIDO DE OXIGENO PEROXIDICO.
