Hydrofluoric acid (40% and 70%), or as it is called, or hydrofluoric Hydrofluoric acid - is a colorless transparent liquid with a pungent odor; easily corrode glass and other materials containing silicon.
The main method of producing hydrofluoric acid reaction of calcium fluorite with sulfuric acid, which is carried out in tubular and rotating screw furnaces at 120-180oS. Reaction gases are purified of dust, are condensed hydrofluoric acid and subjecting it to a two-stage rectification. In the laboratory, hydrofluoric acid are conveniently prepared by thermal decomposition of hydrofluoride.
Hydrofluoric acid (Hydrofluoric acid) is intended to break rocks silicate, dissolution of metals (tantalum, zirconium, niobium, et al.), As a hydrogenation catalyst and a dehydrogenation catalyst in the alkylation of organic chemistry, the reagent in the production of halocarbons and fluoroplastics, a starting material for producing fluorine production fluorosulfonic acid. Hydrofluoric acid is used
• in metallurgical,
• in the oil and gas industry,
• Building Materials Industry
• chemical polishing crystal products and processing of glass and other.
