| Isobutylamine Usage And Synthesis |
| Chemical Properties | Clear colorless to slightly yellow liquid | | Chemical Properties | Butyl amines are highly flammable, colorless
liquids (n-turns yellow on standing) with ammoniacal or fishlike odors. n-isomer: | | Chemical Properties | Colorless to yellow liquid; fishy cheesy aroma. | | Chemical Properties | Isobutylamine is a flammable liquid, miscible with water, alcohol, and
ether. | | Uses | Isobutylamine is used as pharmaceutical intermediate. | | Uses | Isobutylamine may be used in the synthesis of N-i-butyl-9(Z),12(Z),15(Z)-octadecatrienamide by reacting with trilinolenin. It can also react with tropolone to form a hydrogen-bonded complex, iso-butyl-ammonium 7-oxo-cyclo-hepta-1,3,5-trien-1-olate. Fullerene (C60) can undergo oxyamination with isobutylamine to form polyamines. | | Uses | Organic synthesis, insecticides. | | Definition | ChEBI: An alkylamine having isobutyl as the alkyl group. It has been isolated from Sambucus nigra (Elderberry). | | Production Methods | Isobutylamine is manufactured from isobutanol and ammonia
or by the thermal decomposition of valine to isoleucine. | | Aroma threshold values | High strength odor, fishy type; recommend smelling in a 0.10% solution or less. | | General Description | A clear colorless liquid with a fishlike odor. Flash point 15°F. Less dense (6.1 lb / gal) than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. | | Air & Water Reactions | Highly flammable. Soluble in water. | | Reactivity Profile | Isobutylamine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. | | Hazard | Flammable, dangerous fire risk. Strong irritant to skin and mucous membranes. | | Health Hazard | Inhalation causes severe coughing and chest pain due to irritation of air passages; can cause lung edema. Compound is sympathomimetic and is also a cardiac depressant and convulsant; ingestion causes nausea and profuse salivation. Contact with eyes causes severe irritation and edema of the cornea. Contact with skin causes severe irritation. | | Chemical Reactivity | Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | | Potential Exposure | Alert: (n-isomer): Possible risk of
forming tumors, suspected of causing genetic defects, suspected reprotoxic hazard, Primary irritant (w/o allergic
reaction), (sec-isomer): Drug. n-Butylamine is used in
pharmaceuticals; dyestuffs, rubber, chemicals, emulsifying
agents; photography, desizing agents for textiles; pesticides, and synthetic agents. sec-Butylamine is used as a
fungistate. tert-Butylamine is used as a chemical intermediate in the production of tert-Butylaminoethyl methacrylate
(a lube oil additive); as an intermediate in the production
of rubber and in rust preventatives and emulsion deterrents
in petroleum products. It is used in the manufacture of
several drugs | | Shipping | UN1125 n-Butylamine, Hazard Class: 3; Labels:
3—Flammable liquid, 8—Corrosive material. UN2014
Isobutylamine, Hazard Class: 3; Labels: 3—Flammable
liquid, 8—Corrosive material | | Incompatibilities | May form explosive mixture with air.
May accumulate static electrical charges, and may causeignition of its vapors. n-Butylamine is a weak base; reacts
with strong oxidizers and acids, causing fire and explosion
hazard. Incompatible with organic anhydrides; isocyanates,
vinyl acetate; acrylates, substituted allyls; alkylene oxides;
epichlorohydrin, ketones, aldehydes, alcohols, glycols, phenols, cresols, caprolactum solution. Attacks some metals in
presence of moisture. The tert-isomer will attack some
forms of plastics | | Waste Disposal | Use a licensed professional
waste disposal service to dispose of this material. Dissolve
or mix the material with a combustible solvent and burn in
a chemical incinerator equipped with an afterburner andscrubber. All federal, state, and local environmental regulations must be observed. |
