Abstract
PROCEDIMIENTO PARA LA PREPARACION DE ACIDO FLUORHIDRICO, HC<1 ASI COMO CO<2, A PARTIR DE COMPUESTOS FLUORADOS ORGANICOS. A LOS COMPUESTOS FLUORADOS ORGANICOS, SE LES AÑADE AGUA HASTA TRANSFORMAR LA TOTALIDAD DEL CLORO Y FLUOR EN HC<1 Y HF; ASI MISMO SE AÑADE OXIGENO EN CANTIDAD SUFICIENTE PARA TRANSFORMAR EN AGUA EL HIDROGENO NO COMBINADO Y EN CO<2 EL CARBONATO COMBINADO TOTAL; LA MEZCLA SE CALIENTA A TEMPERATURAS A LAS QUE TIENE LUGAR LA FORMACION DE FLUORURO DE HIDROGENO Y A CONTINUACION SE SEPARA A PARTIR DE LA MEZCLA RESULTANTE EL ACIDO FLUORHIDRICO PRODUCIDO, EL CUAL SE AISLA POR CONDENSACION. LOS COMPUESTOS FLUORADOS EMPLEADOS TIENEN UNA PROPORCION DE ATOMOS FLUOR/CLORO NO SUPERIOR A 1,0.
