N-METHYLBUTYLAMINE Usage And Synthesis

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:

Uses

Intermediate.

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. See also AMINES.

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.
