化学的特性

n-Butylamine is a derivative of ammonia in which one of the hydrogen atoms is replaced with an alkyl group of four carbons. As such, it reacts with water and acids to form bases and salts, respectively. Acting as a very weak acid, it can react with acyl halides, anhydrides, and esters. With carbon disulfide and carbon dioxide, it forms the butyl ammonium salt of dithiocarbamic and carbamic acids, respectively. With isocyanic acid and alkyl or aryl isocyanates, it forms substituted ureas. When reacted with nitrous acid, rc-butylamine forms butyl alcohol with the release of nitrogen (Schweizer et al 1978). In the presence of water, rc-butylamine may corrode some metals (General Electric Co 1986) and attack glass (Schweizer et al 1978). Liquid n-butylamine also will attack some forms of plastics, rubber, and coatings (NIOSH 1981).

説明

n-Butylamine is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a colourless to yellow liquid and is highly flammable. It is stable and incompatible with oxidising agents, aluminium, copper, copper alloys, and acids. n-Butylamine finds its uses in the manufacture of pesticides (such as thiocarbazides), pharmaceuticals, and emulsifiers. It is also a precursor for the manufacture of N,N′-dibutylthiourea, a rubber vulcanisation accelerator, and n-butylbenzenesulphonamide, a plasticiser of nylon.

天然物の起源

Reported found in mulberry leaves, kale, tomato, tilsit cheese, cheddar and other cheeses, caviar, fish, cooked chicken, cooked beef, beer, sherry and red wine.

使用

n-Butylamine is used as an intermediatefor various products, including dyestuffs,pharmaceuticals, rubber chemical, synthetictanning agents, and emulsifying agents. It isused for making isocyanates for coatings.

一般的な説明

A clear colorless liquid with an ammonia-like odor. Flash point 10°F. Less dense (6.2 lb / gal) than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion.

製法・合成法

製造方法

Catalytic alkylation of ammonia with butyl alcohol.

調製方法

n-Butylamine is usually manufactured by the catalytic alkylation of ammonia with butyl alcohol, or similarly from butyraldehyde and ammonia in the presence of Raney nickel. U.S. production in 1982 was approximately 1109 metric tons (SRI 1985). Some n-butylamine is also produced as a result of fertilizer manufacture, fish processing, rendering plant operations, and sewage treatment and has been reported to be a component of animal waste (Graedel 1978).

純化方法

Dry it with solid KOH, K2CO3, LiAlH4, CaH2 or MgSO4, then reflux it with, and fractionally distil it from P2O5, CaH2, CaO or BaO. Further purification is by precipitation as the hydrochloride, m 213-213.5o, from ethereal solution by bubbling HCl gas into it. This is re-precipitated three times from EtOH by adding ether, followed by liberation of the free amine using excess strong base. The amine is extracted into ether, which is separated, dried with solid KOH, the ether removed by evaporation and then the amine is distilled. It is stored in a desiccator over solid NaOH [Bunnett & Davis J Am Chem Soc 82 665 1960, Lycan et al. Org Synth Coll Vol II 319 1943]. [Beilstein 4 IV 540.] SKIN IRRITANT.

応急処置EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting. Thus, the risk of increasing the medical problems by inducing vomiting of a volatile corrosive chemical is very high. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)General First Aid:· Call 911 or emergency medical service.· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.· Move victim to fresh air if it can be done safely.· Administer oxygen if breathing is difficult.· If victim is not breathing:-- DO NOT perform mouth-to-mouth resuscitationthe victim may have ingested or inhaled the substance.-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.· Remove and isolate contaminated clothing and shoes.· For minor skin contact, avoid spreading material on unaffected skin.· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.· For severe burns, immediate medical attention is required.· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.· Keep victim calm and warm.· Keep victim under observation.· For further assistance, contact your local Poison Control Center.· Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.Specific First Aid:· For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes.

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), Koc values ranging from 15 to 107(2) indicate that n-butylamine is expected to have high mobility in soil(SRC). The pKa of n-butylamine is 10.78(3) indicating that this compound will exist almost entirely in the cation form in the environment and therefore volatilization from moist soil surfaces is not expected to be an important fate process(SRC). The potential for volatilization of n-butylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 92.9 mm Hg(4). Numerous screening studies indicate that n-butylamine will biodegrade readily(5-8)n-butylamine reached 67% of its theoretical BOD in 12 days using an activated sludge inoculum(5).AQUATIC FATE: Based on a classification scheme(1), a Koc value range of 15 to 107 in soil and sediment(2), indicates that n-butylamine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 10.78(3) indicates n-butylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Milk Concentrations... The presence of volatile aliphatic amines ... in human breast milk and amniotic fluid /was measured/ to assess their role in neonatal hypergastrinemia. These volatile nitrogenous amino acid metabolites have been previously demonstrated to stimulate gastrin release in in vivo and in vitro laboratory preparations. ... The present study ... demonstrated that these gastrin-stimulatory volatile amines were present in significant concentrations in breast milk during the first several weeks after parturition and in amniotic fluid. The individual amines that were identified in both human milk and amniotic fluid samples were methylamine, dimethylamine, ethylamine, trimethylamine, propylamine, isobutylamine, and butylamine. This study provides indirect evidence to support the possibility that the hypergastrinemia measured in the fetus/neonate during the period immediately before and after birth may be attributable, in part, to the ingestion of fluid containing high concentrations of gastrin-stimulating amines.
