Triethylamine is a tertiary amine (Et3N) with a large number of uses in chemical manufacture. It is commonly used in organic synthesis as a base.

Benco Chemical has over 15 years experience supplying Triethylamine (TEA) to the North American market.

Triethylamine Manufacturing Process

Alkylation of ammonia occurs when ethanol and ammonia are reacted under heat and a catalyst to produce ethylamine. This continuous process also leads to further alkylation producing diethylamine and triethylamine.

This mixture of alkyl amines is then separated via distillation. The triethylamine distillate has high purity (99.5%) and low moisture content (<0.1%). TEA appears as a colourless liquid with ammonia like odour. 

Triethylamine Application Areas

Some of its major uses in industry include:

• Catalyst to cure resin systems incorporated into sand cores for
   foundry molds.
• Used for the precipitation and purification of antibiotics, such as penicillin.
• Used as a catalyst for isocyanate reactions, for example as a cross-linking
  catalyst in the production of polyurethane foams.
• Catalyst for epoxy resins.

TEA has a broad range of miscellaneous applications:

• Production of herbicides, such as 2,4-D.
• Production of polycarbonate resins.
• A neutralization agent in waterborne paints based on polyesters, alkyds, 
  acrylic resins and polyurethanes containing acidic groups.

• Curing catalyst in particleboard adhesives.
• Corrosion inhibitor for polymers.
• Production of Diethylhydroxylamine and other amine derivatives.
