Description du produit
Product Description Product introduction
Hydrofluoric acid (English: Hydrofluoric Acid [1]) is an aqueous solution of hydrogen fluoride gas, clear, colorless, smoke corrosive liquid with a severe irritating odor. A melting point of -83.3 ° C, a boiling point of 19.54 ° C, a flash point of 112.2 ° C and a density of 1.15 g / cm³. Soluble in water, ethanol, slightly soluble in ether.
Characteristic and superiority
Because of the relatively strong ability of hydrogen atoms and fluorine atoms to bind, and the presence of hydrogen bonds between the hydrogen fluoride molecules in the aqueous solution, hydrofluoric acid can not be completely ionized in water, theoretically low concentrations of hydrofluoric acid are a weak acid. Has a strong corrosive, can strongly corrode metal, glass and silicon-containing objects. Such as inhalation of steam or contact with the skin can cause incurable burns. Laboratory generally with fluorite (the main component of calcium fluoride) and concentrated sulfuric acid to make, need to be sealed in plastic bottles, and preserved in the shade.
Application
Due to the ability of hydrofluoric acid to dissolve oxides, it plays an important role in the purification of aluminum and uranium. Hydrofluoric acid is also used to etch the glass, which can be engraved, marked and text; the semiconductor industry uses it to remove the oxide on the silicon surface, which can be used as an alkylation of isobutane and n-butene in a refinery Catalyst, Hydrofluoric acid is also used for the synthesis of a variety of fluorine-containing organic compounds, such as Teflon (polytetrafluoroethylene) and freon class of refrigerant.
