Abstract
SE DESCRIBE UN PROCESO PARA LA ELABORACION DE CLORUROS DE POLIFLUOR CLORO Y PERFLUOR ACIDO CARBOXILICO, POR EJEMPLO LA ELABORACION DE CLORURO DE ACIDO PERFLUOR PROPIONICO, CLORURO DE CLORODIFLUOR ACETIL Y LA ELABORACION DE CLORURO TRIFLUOR ACETIL. PARA ELLO SE UTILIZAN MATERIALES DE PARTIDA, QUE MUESTRAN UN GRUPO CHCL2, QUE MEDIANTE OXIDACION FOTOQUIMICA SE TRANSFORMAN CON OXIGENO BAJO ADICION DE CLORO Y RADIACION ACTIVADA EN EL GRUPO C(O)CL. LA TRANSFORMACION SE REALIZA DE TAL MODO, QUE SE RADIA CON LUZ DE UNA LONGITUD DE ONDA LAMBDA MAYOR O IGUAL DE 290 NM. CON PREFERENCIA SE TRABAJA SIN PRESION. LA TRANSFORMACION PREDOMINANTE SE REALIZA CON ALTA SELECTIVIDAD BAJO LA UTILIZACION DE RADIADOR HG DOTADO.
