Isobutylamine Chemical Properties,Usage,Production
Chemical Properties
Isobutylamine is a flammable liquid, miscible with water, alcohol, and
ether. Colorless to yellow liquid; fishy cheesy aroma.
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.
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
Isobutylamine is 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.
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.
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
Isobutylamine: 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.
