Abstract

EN LA INVENCION SE PRESENTAN UN METODO Y UN EQUIPO PARA LA PRODUCCION DE UN COMPUESTO DE FLUOCARBURO DESEADO QUE CONSISTE EN FORMAR UNA ZONA DE ALTA TEMPERATURA Y ALIMENTAR AL MENOS UN MATERIAL DE ENTRADA EN LA ZONA DE ALTA TEMPERATURA PARA GENERAR UN CUERPO DE GAS CALIENTE QUE INCLUYA ESPECIES QUE CONTENGAN FLUOR Y ESPECIES QUE CONTENGAN CARBONO. LA RELACION MOLAR C:F DEL CUERPO DE GAS CALIENTE SE CONTROLA DE MODO QUE TENGA UN VALOR SELECCIONADO DE ENTRE 0,4 Y 2; Y LA ENTALPIA ESPECIFICA DEL CUERPO DE GAS CALIENTE SE CONTROLA DE MODO QUE SEA DE ENTRE 1KWH/KG APROXIMADAMENTE Y 10KWH/KG APROXIMADAMENTE DURANTE UN INTERVALO DE TIEMPO DE TAL MODO QUE SE FORME UNA MEZCLA GASEOSA TERMICA REACTIVA, QUE CONTENGA ESPECIES REACTIVAS QUE INCLUYAN PRECURSORES REACTIVOS QUE CONTENGAN FLUOR Y PRECURSORES REACTIVOS QUE CONTENGAN CARBONO. A CONTINUACION SE REFRIGERA LA MEZCLA TERMICA REACTIVA A UNA VELOCIDAD DE REFRIGERACION Y A UNA TEMPERATURA DE REFRIGERACION SELECCIONADAS PARA OBTENER UN PRODUCTO FINALQUE INCLUYE EL COMPUESTO DE FLUOCARBURO DESEADO. EL MATERIAL DE ENTRADA ES NORMALMENTE UN COMPUESTO DE CARBONO PERFLUORADO C1-C10 DE LA FORMULA GENERAL CNFM EN LA QUE 0 < N (MENOR O IGUAL) 10 Y M = 2N, 2N + 2, O 2N EMPLO UN FLUOCARBURO GASEOSO TAL COMO TETRAFLUOMETANO (CF4).
