Abstract
PROCESO PARA SEPARAR Y RECUPERAR EL FLUORURO DE HIDROGENO DE UNA MEZCLA CON UN COMPUESTO ORGANICO, ESPECIALMENTE UN COMPUESTO QUE CONTENGA FLUOR, MEDIANTE UNA EXTRACCION CON UNA SOLUCION DE FLUORURO DE METAL ALCALINO EN FLUORURO DE HIDROGENO, UNA SEPARACION DE FASES Y UNA RECUPERACION. PROCESO PARA PRODUCIR UN COMPUESTO ORGANICO QUE CONTENGA FLUOR, FLUORANDO LA MATERIA PRIMA CON FLUORURO DE HIDROGENO Y RECUPERANDO DE FORMA SEMEJANTE EL FLUORURO DE HIDROGENO DE LA CORRIENTE DE PRODUCTO. LA SOLUCION PUEDE SER ANHIDRA O ACUOSA.
