• 개요

  Ammonium hydroxide is a colorless, liquid solution with a characteristic and pungent odor. It is ammonia combined with water. Ammonia (NH3) is a compound consisting of nitrogen and hydrogen. Both ammonia and ammonium hydroxide are very common compounds, found naturally in the environment (in air, water, and soil) and in all plants and animals, including humans. Ammonia is a source of nitrogen, an essential element for plants and animals. Ammonia is also produced by the human body – by our organs and tissues and by beneficial bacteria living in our intestines.
  Ammonia plays an important role in protein synthesis in the human body. In brief summary, all living things need proteins, which are comprised of some 20 different amino acids. While plants and microorganisms can synthesize most amino acids from the nitrogen in the atmosphere, animals cannot. For humans, some amino acids cannot be synthesized at all and must be consumed as intact amino acids. Other amino acids, however, can be synthesized by microorganisms in the gastrointestinal tract with the help of ammonia ions. Thus, ammonia is a key player in the nitrogen cycle and in protein synthesis. Ammonia also helps maintain the body's pH balance.

• 화학적 성질

  Ammonium hydroxide exists only in the form of an aqueous solution. The compound is prepared by dissolving NH3 in H2O and usually is referred to in industrial trade as aqua ammonia. For industrial procurements, the concentration of NH3 in solution is normally specified in terms of the specific gravity (degrees Baum′e, °Be). Common concentrations are 20 °Be and 26 °Be. The former is equivalent to a sp gr of 0.933, or a concentration of about 17.8% NH3 in solution; the latter is equivalent to a sp gr of 0.897, or a concentration of about 29.4% NH3. These figures apply at a temperature of 60 °F (15.6 °C). Reagent grade NH4OH usually contains approximately 58% NH4OH (from 28 to 30% NH3 in solution).

• 용도

  Ammonium hydroxide is used as a cleaning agent and sanitizer in many household and industrial cleaners. Ammonium hydroxide is also used in the manufacture of products such as fertilizer, plastic, rayon and rubber. Aqueous ammonia is corrosive to aluminum alloys, copper, copper alloys, and galvanized surfaces. Aqueous ammonia is an excellent acid neutralizer.

• 정의

  Ammonium hydroxide,NH40H, is a hydrate of anunonia and exists in crystalline form at -79°C. Normally, it is only found in an aqueous solution also known as aquaanunonia and anunonia water. It is prepared by dissolving NH3 inH20. Reagent grade anunonium hydroxide contains from 28 to 30% NH3 at 15.6 °C. Industrial sales specify the concentration of NH3 in solution in terms of specific gravity. Common concentrations are 20 °Be, which would bea concentration of 17.8% NH3 (specific gravity 0.933) and 26 °Be (specific gravity 0.897), or a concentration of 29.4% NH3. Ammonium hydroxide is an excellent medium for the reaction of NH3 (which becomes the NH4 radical in solution) with other compounds for the preparation of anunonium salts and other nitrogen-containing chemicals. It is an ingredientin deodorants, etching compounds, and cleaning and bleaching materials. Ammoniumhydroxide, as aqua ammonia, finds wide use as a neutralizing agent,because it is inexpensive and strongly alkaline.

• 일반 설명

  Ammonium hydroxide is a colorless aqueous solution. Concentration of ammonia ranges up to approximately 30%. Ammonia vapors (which arise from the solution) irritate the eyes.

• 공기와 물의 반응

  Water soluble. Generates a small amount of heat when diluted with water.

• 반응 프로필

  Ammonium hydroxide reacts exothermically with acids. Evolves toxic gaseous ammonia with strong bases. Reacts extremely violently with dimethyl sulfate [NFPA 491M 1991]. Reacts with aqueous silver nitrate sodium hydroxide to give a black precipitate of silver nitride. Such a precipitate can explode on stirring [MCA Case History 1554 1968]. Aqueous ammonia and Hg react to form an explosive solid, likely a fulminate. (Thodos, G. Amer. Inst. Chen. Engrs. J., 1964, 10, 274.).

• 위험도

  Liquid and vapor extremely irritating, especially to eyes.

• 건강위험

  Ammonium hydroxide solutions are alkaline solutions, meaning they have high pH level. As a result, ammonium hydroxide is a severe eye, skin, and respiratory tract irritant, and readily burns tissue with which it comes in contact. Splashes to the eye may be serious, as contact may cause severe burns, irritation pain and possibly blindness. Direct contact with skin may cause severe burns if the chemical is not quickly rinsed away with copious amounts of water. Inhaling mists of ammonium hydroxide may result in irritation of the nose and throat with symptoms including burning, coughing, choking and pain. Inhaling concentrated mist may result in pulmonary edema and shock. Ingesting ammonium hydroxide may cause pain and burns of the esophagus and gastrointestinal tract.
  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.

• 화재위험

  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.

• 인화성 및 폭발성

  Ammonia vapor is slightly flammable (NFPA rating = 1) and ignites only with difficulty. Ammonia forms explosive mixtures with air in the range 16 to 25%. Water, carbon dioxide, or dry chemical extinguishers should be used for ammonia fires.

• 농업용

  Ammonium hydroxide is also known as ammonia solution, aqua ammonia, aqueous ammonia or ammonia liquor. It is the solution of ammonia in water and is commonly referred to as ammonium hydroxide. It is the simplest nitrogen solution made by forcing compressed ammonia (anhydrous ammonia) gas into water.

• Safety Profile

  A human poison by ingestion. An experimental poison by inhalation and ingestion. A severe eye irritant. Human systemic irritant effects by ocular and inhalation routes. Mutation data reported. Incompatible with acrolein, nitromethane, acrylic acid, chlorosulfonic acid, dimethyl sulfate, halogens, (Au + aqua regia), HCl, HF, HNO3, oleum, ppropiolactone, propylene oxide, AgNO3, Ag2O, (Ag20 + C2H5OH), AgMn04, H2SO4. Dangerous; liquid can inflict burns. Use with adequate ventilation. When heated to decomposition it emits NH3 and NO2.

• 잠재적 노출

  It is used in detergents, stain removers, bleaches, dyes, fibers, and resins.

• 저장

  All work with this substance should be conducted in a fume hood to prevent exposure by inhalation, and splash goggles and impermeable gloves should be worn at all times to prevent eye and skin contact.
  Containers should be tightly sealed to prevent escape of vapor and should be stored in a cool area separate from halogens, acids, and oxidizers. Containers stored in warm locations may build up dangerous internal pressures of ammonia gas.
