Dibutylamine is an amine in the form of colorless liquid. It is miscible with almost all common organic solvents, and has limited miscibility with water. It is flammable, toxic, and corrosive to the skin and eyes.

Applications

In oilfield, it is often used as a corrosion inhibitor and in the manufacture of emulsifiers. It is also used as intermediate in the production of:

• pharmaceuticals
• agricultural chemicals
• dye intermediates
• printing inks
• paper
• leather
• textile and dye auxiliaries
• photographic chemicals
• plasticizers
• additives for fuels and lubricants
• flotation agents
• rubber accelerators
• curing agents for epoxy resins
• catalysts for polyurethane resins

Shelf life

Dibutylamine has an almost unlimited shelf life in unopened, original containers.

Safety

Direct contact results in burns and eye injury. Ingestion results in damage to the gastrointestinal tract. Inhalation of vapors may irritate the respiratory tract. Inhalation may be fatal as a result of spasms, inflammation and edema of the larynx and bronchi.Overexposure may result in sensitization.
