説明

Hydrofluoric acid is a solution of hydrogen fluoride in water. Hydrofluoric acid is highly corrosive inorganic acid. It is utilized widely in the manufacture of ceramics and graphite, in the electropolishing and pickling of metals, in the etching and frosting of glass, in the semiconductor industry as etchant and cleaning agent, in the chemical and oil-refining industries, and in cleaning solutions, laundry powder and pesticides. Hydrofluoric acid is also widely used in the preparation of many useful fluorine compounds, such as Teflon, Freon, fluorocarbons, and many medications such as fluoxetine (Prozac).

化学的特性

colourless gas with a pungent odour

物理的性質

Colorless gas or liquid at ambient temperatures; fumes in air; highly irritating; gas density 0.878 g/L at 25°C; liquid density 1.002 g/mL at 0°C; boils at 19.85°C; freezes at –83.55°C; vapor pressure 360 torr at 0°C; critical temperature 187.85°C; critical pressure 63.95 atm; critical volume 69 cm3/mol; viscosity 0.256 centipoise at 0°C; surface tension 10.1x10–4 dyn/cm at 0°C; dielectric constant 83.6 at 0°C; highly soluble in water and alcohols; forms an azeotrope with water at a composition 38.2 HF: 61.8 H2O (weight percent); the azeotrope boils at 112.2°C; moderately soluble in benzene (2.55 g/100 g at 5°C). Hydrofluoric acid is a colorless, fuming liquid which is an aqueous solution of hydrogen fluoride; densities of 20%, 40% and 60% acid at 20°C are 1.070, 1.135, and 1.215 g/mL, respectively; a 70% solution boils at 66.4°C; the same solution freezes at –69°C to a solid phase that has a composition of HF•H2O; vapor pressure of 70% solution at 25°C 150 torr; partial pressures of HF over HF—H2O solutions at 20°C are 0.412, 12.4 and 115.3 torr, respectively, for 20, 50 and 70% HF solutions by weight; equivalent conductance of 0.01 M and 0.1 M solutions at 20°C, 93.5 and 37.7 mhos-cm2, respectively; a weak acid, pKa 3.20 at 25°C; a 0.1M aqueous solution ionized <10%

使用

Cleaning cast iron, copper, brass; removing efflorescence from brick and stone, or sand particles from metallic castings; working over too heavily weighted silks; frosting, etching glass and enamel; polishing crystal glass; decomposing cellulose; enameling and galvanizing iron; increasing porosity of ceramics. Its salts are used as insecticides and to arrest undesirable fermentation in brewing. Also used in analytical work to determine SiO2, etc.

使用

Hydrofluoric acid is used as a fluorinatingagent, as a catalyst, and in uranium refining.It is also used for etching glass and forpickling stainless steel. Hydrogen fluoridegas is produced when an inorganic fluoride is distilled with concentrated sulfuricacid.

定義

A colorless liquid produced by dissolving hydrogen fluoride in water. It is a weak acid, but will dissolve most silicates and hence can be used to etch glass. As the interatomic distance in HF is relatively small, the H–F bond energy is very high and hydrogen fluoride is not a good proton donor. It does, however, form hydrogen bonds.

定義

ChEBI: A diatomic molecule containing covalently bonded hydrogen and fluorine atoms.

反応性

Although anhydrous hydrogen fluoride is a very strong acid, its aqueous solution, hydrofluoric acid, is weakly acidic, particularly when dilute. The Ka value of aqueous acid at 25°C is 6.46x10–4 mol/L. It is an excellent solvent for many inorganic fluorides, forming bifluoride anion:

HF + NaF → Na+ + HF2¯ At lower temperatures (below 200°C), HF forms molecular aggregates that are held by hydrogen bonding containing linear chains of –F—H—-F—H—- F—H—-. However, above this temperature the weak hydrogen bond breaks producing monomolecular HF. Thermal dissociation of HF into elements probably occurs only at very high temperatures. Forty to 50% HF probably dissociates around 4,000°C, indicating that it is one of the most stable diatomic molecules. The most important reactions of HF involve formation of inorganic fluoridesalts. HF gas or hydrofluoric acid reacts with oxides, hydroxides, carbonates, chlorides and other metal salts forming the corresponding fluorides. Some examples are:

Bi2O3 + 6HF → 2BiF3 + 3H2O

LiOH + HF → LiF + H2O

CaCO3 + 2HF → CaF2 +CO2 + H2O

FeCl3 + 3HF → FeF3 + 3HCl

CoCl2 + 2HF → CoF2 + 2HCl Reaction with potassium dichromate yields chromyl fluoride:

K2Cr2O7 + 6HF → 2CrO2F2 + 2KF + 3H2O When ammonia gas is bubbled through a 40% ice-cold solution of hydrofluoric acid, the product is ammonium fluoride:

NH3 + HF → NH4F The addition of equimolar amount of NaOH or Na2CO3 to 40% HF instantaneously precipitates NaF:

NaOH + HF → NaF + H2O Excess HF, however, yields sodium bifluoride, NaHF2:

NaOH + 2HF → NaHF2 + H2O Reaction with phosphorus trichloride yields phosphorus trifluoride; and with phosphoryl fluoride and sulfur trioxide, the product is phosphorus pentafluoride:

PCl3 + 3HF → PF3 + HCl

POF3 + 2HF + SO3 → PF5 + H2SO4

空気と水の反応

Fumes in air. Fumes are highly irritating, corrosive, and poisonous. Generates much heat on dissolution [Merck, 11th ed., 1989]. Heat can cause spattering, fuming, etc.

反応プロフィール

Hydrofluoric acid attacks glass and any other silica containing material. May react with common metals (iron, steel) to generate flammable hydrogen gas if diluted below 65% with water. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). Can initiate polymerization in certain alkenes. Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. May generate flammable and/or toxic gases with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides. Additional gas-generating reactions may occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. Can catalyze (increase the rate of) chemical reactions. Reacts explosively with cyanogen fluoride, methanesulfonic acid or glycerol mixed with nitric acid. Reacts violently with arsenic trioxide, phosphorus pentachloride, acetic anhydride, alkali metals, ammonium hydroxide, chlorosulfonic acid, ethylenediamine, fluorine, potassium permanganate, oleum, propylene oxide, vinyl acetate, mercury(II) oxide. Emits highly corrosive fumes of hydrogen fluoride gas when heated [Sax, 9th ed., 1996, p. 1839]. Contact with many silicon compounds and metal silicides causes violent evolution of gaseous silicon tetrafluoride [Mellor, 1956, Vol. 2, suppl. 1, p. 121].

危険性

Toxic by ingestion and inhalation, highly corrosive to skin and mucous membranes.

健康ハザード

Anhydrous hydrogen fluoride and hydrofluoric acid are extremely corrosive to all tissues of the body. Skin contact results in painful deep-seated burns that are slow to heal. Burns from dilute (<50%) HF solutions do not usually become apparent until several hours after exposure; more concentrated solutions and anhydrous HF cause immediate painful burns and tissue destruction. HF burns pose unique dangers distinct from other acids such as HCl and H2SO4: undissociated HF readily penetrates the skin, damaging underlying tissue; fluoride ion can then cause destruction of soft tissues and decalcification of the bones. Hydrofluoric acid and HF vapor can cause severe burns to the eyes, which may lead to permanent damage and blindness. At 10 to 15 ppm, HF vapor is irritating to the eyes, skin, and respiratory tract. Exposure to higher concentrations can result in serious damage to the lungs, and fatal pulmonary edema may develop after a delay of several hours. Brief exposure (5 min) to 50 to 250 ppm may be fatal to humans. Ingestion of HF can produce severe injury to the mouth, throat, and gastrointestinal tract and may be fatal. HF has not been reported to be a human carcinogen. No acceptable animal test reports are available to define the developmental or reproductive toxicity of this substance

健康ハザード

Hydrofluoric acid and hydrogen fluoride gasare extremely corrosive to body tissues, causing severe burns. The acid can penetrate theskin and destroy the tissues beneath and evenaffect the bones. Contact with dilute acid cancause burns, which may be perceptible hoursafter the exposure. The healing is slow. Contact with the eyes can result in impairment ofvision.
Prolonged exposure to 10–15 ppm concentrations of the gas may cause redness ofskin and irritation of the nose and eyes inhumans. Inhalation of high concentrations ofHF may produce fluorosis and pulmonaryedema. In animals, repeated exposure toHF gas within the range 20–25 ppm hasproduced injury to the lungs, liver, andkidneys.
LC50 value, inhalation (mice): 342 ppm/h.

健康ハザード

Ingestion of an estimated 1.5 grams produced sudden death without gross pathological damage. Repeated ingestion of small amounts resulted in moderately advanced hardening of the bones. Contact of skin with anhydrous liquid produces severe burns. Inhalation of anhydrous hydrogen fluoride or hydrogen fluoride mist or vapors can cause severe respiratory tract irritation that may be fatal.

火災危険

When heated, Hydrofluoric acid emits highly corrosive fumes of fluorides. Its corrosive action on metals can result in formation of hydrogen in containers and piping to create fire hazard. Toxic and irritating vapors are generated when heated. Will attack glass, concrete, and certain metals, especially those containing silica, such as cast iron. Will attack natural rubber, leather, and many organic materials. May generate flammable hydrogen gas in contact with some metals.

火災危険

Hydrogen fluoride is not a combustible substance

燃焼性と爆発性

Hydrogen fluoride is not a combustible substance

貯蔵

All work with HF should be conducted in a fume hood to prevent exposure by inhalation, and splash goggles and neoprene gloves should be worn at all times to prevent eye and skin contact. Containers of HF should be stored in secondary containers made of polyethylene in areas separate from incompatible materials. Work with anhydrous HF should be undertaken using special equipment and only by well-trained personnel familiar with first aid procedures.

純化方法

It can be purified by trap-to-trap distillation, followed by drying over CoF2 at room temperature and further distillation. Alternatively, it can be absorbed on NaF to form NaHF2 which is then heated under vacuum at 150o to remove volatile impurities. The HF is regenerated by heating at 300o and is stored with CoF3 in a nickel vessel, being distilled as required. (Water content should be ca 0.01%.) To avoid contact with base metal, use can be made of nickel, polychlorotrifluoroethylene and gold-lined fittings [Hyman et al. J Am Chem Soc 79 3668 1957]. An aqueous solution is hydrofluoric acid (see above). It is HIGHLY TOXIC and attacks glass.

不和合性

HF reacts with glass, ceramics, and some metals. Reactions with metals may generate potentially explosive hydrogen gas.

廃棄物の処理

Excess hydrogen fluoride and waste material containing this substance should be placed in an appropriate container, clearly labeled, and handled according to your institution's waste disposal guidelines. For more information on disposal procedures, see Chapter 7 of this volume.
