Description
Apearances: The color
slightly sour smell crystallization. Hydrofluoric acid, is not lost in the dry
air to absorb moisture in humid air and hydrogen fluoride to escape, the water
is decomposed into potassium fluoride and hydrofluoric acid. The soluble
potassium acetate, soluble in dilute ethanol, not soluble in ethanol. Aqueous
acidic reaction. Toxic. Corrosive.
USES
Alkylated benzene catalysts. Glass pitting
painted. Manufacture of fluorine. Metallurgical flux.
