Abstract
UN PROCEDIMIENTO PARA LA PRODUCCION DE ACIDO FLUORHIDRICO ANHIDRO.METODO PARA LA PRODUCCION DE ACIDO FLUORHIDRICO ANHIDRO A PARTIR DE FLUORUROS METALICOS DE BAJA CALIDAD, UTILIZANDO UN COMPUESTO INTERMEDIO DE FLUORURO ALUMINICO.EL METODO IMPLICA LA REACCION DE FLUORUROS METALICOS DE BAJA CALIDAD, TALES COMO EL ESPATO FLUOR, CON ACIDO SULFURICO PARA PRODUCIR ACIDO FLUORHIDRICO DILUIDO. EL ACIDO DILUIDO SE HACE LUEGO REACCIONAR CON UNA SAL METALICA (TAL COMO EL CLORURO ALUMINICO) PARA FORMAR FLUORURO ALUMINICO PRECIPITADO (ALF3.3H2O). DESPUES DE DESECAR, SE HACE REACCIONAR EL FLUORURO ALUMINICO CON ACIDO SULFURICO CONCENTRADO PARA FOMAR SULFATO ALUMINICO Y ACIDO FLUORHIDRICO CONCENTRADO.
