Chemical Properties
CLEAR COLOURLESS LIQUID
Chemical Properties
Butyl amines are highly flammable, colorless
liquids (n-turns yellow on standing) with ammoniacal or fishlike odors. n-isomer:
Definition
ChEBI: A secondary aliphatic amine having methyl and n-butyl as the two alkyl groups.
General Description
A water-white liquid with an ammonia-like odor. Density 0.736 g / cm3 and flash point 35°F (Aldrich) .Vapors heavier than air. Used to make other chemicals.
Air & Water Reactions
Highly flammable. Slightly soluble in water.
Reactivity Profile
N-METHYLBUTYLAMINE 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.
Health Hazard
May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Poison by intravenous
route. Moderately toxic by ingestion, skin
contact, and intraperitoneal routes. Mildly
toxic by inhalation. A skin and severe eye
irritant. Flammable liquid when exposed to
heat, sparks, or flame. To fight fire, use
alcohol foam. When heated to
decomposition it emits toxic fumes of NOx.

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
