酸性フッ化アンモニウム 化学特性,用途語,生産方法

• 外観

  白色, 結晶～結晶性粉末

• 溶解性

  水に易溶 (60.15g/100ml水, 20℃), エタノールに微溶。水に極めて溶けやすく，エタノールに溶けにくい。

• 用途

  医療用，金属の表面処理剤、発酵工業におけるホースや導管等の消毒用、あるいは木材の防腐用に使われる。

• 使用上の注意

  ガラスを腐食する。

• 化学的特性

  white scales or flakes, also referred to asammonium hydrogen fluoride, anunonium difluoride and anunonium acid fluoride.

• 物理的性質

  Orthorhombic or tetragonal crystals; etches glass; deliquescent; density 1.50 g/cm3; refractive index 1.390; melts at 125.6°C; very soluble in water; slightly soluble in alcohol.

• 使用

  In manufacture of Mg and Mg alloys; in brightening of Al; for purifying and cleansing various parts of beer-dispensing apparatus, tubes, etc., sterilizing dairy and other food equipment; in glass and porcelain industries; as mordant for aluminum; as a "sour" in laundering cloth. In lab production of HF.

• 一般的な説明

  Ammonium bifluoride solution is the white crystalline solid dissolved in water. Ammonium hydrogen difluoride is corrosive to metals and tissue. Ammonium hydrogen difluoride is used in ceramics.

• 空気と水の反応

  Dissolves in water and forms a weak solution of hydrofluoric acid.

• 反応プロフィール

  AMMONIUM BIFLUORIDE reacts violently with bases. In presence of moisture will corrode glass, cement, and most metals. Flammable hydrogen gas may collect in enclosed spaces. Do not use steel, nickel, or aluminum containers [USCG, 1999].

• 危険性

  Corrosive to skin.

• 健康ハザード

  TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• 火災危険

  Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

• 安全性プロファイル

  Caustic poison and strong irritant by all routes. See also HYDROFLUORIC ACID. When heated to decomposition it emits very toxic fumes of F-, NO,, and NH3.

• 職業ばく露

  It is used as a sterilizer, in dairy and brewery operations; in the ceramic, glass, and electroplating industries; as a laundry sour.

• 輸送方法

  Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

• Properties and Applications

  Ammonium hydrogen difluoride (NH4HF2) is an inexpensive reagent compared to known anticaries fluorides such as NaF, SnF2, etc. In addition, ammonium bifluoride is reported as a potent inhibitor of caries-like lesion formation in vitro. For instance, Tyler and Poole have studied fluoride uptake by human surface enamel from ammonium bifluoride in vitro. They noticed a reduction in the penetration of caries-like lesions in the case of specimens treated with 1% aq. NH4HF2.  A study reports the fluorination of hydroxyapatite powder using ammonium hydrogen difluoride as a fluorinating agent by three different routes, viz., solid-state method, reflux method, and pH cycle method. The FT-IR and powder XRD results confirm the inter-diffusion of ‘F’ and ‘OH’- ions and the formation of homogeneous products of partially fluorinated hydroxyapatite. Compared to many other fluoride sources, NH4HF2 has the advantages of solubility and cost[1].

• 不和合性

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. In the presence of moisture corrodes concrete, metals, glass.

• 廃棄物の処理

  May be buried in a specially designated chemical landfill. Aqueous wastes may be reacted with an excess of lime followed by lagooning and either recovery or land disposal of the separated calcium fluoride.
