General information

Triethylamine is commonly used as a base during the preparation of esters and amides from acyl chlorides. It is mainly used in the production of quaternary ammonium compounds for textile auxiliaries and quaternary ammonium salts of dyes. It acts as a catalyst and acid neutralizer for condensation reactions and is useful as an intermediate for manufacturing medicines, pesticides and other chemicals.

Health & Safety

  • Triethylamine is irritating to the skin, eyes, and mucous membrane. In case of contact, the affected area should be washed with plenty of water, at least for 15 minutes. A dilute solution of Acetic Acid (2%) should be used to neutralize the amine. Continuous inhalation of fumes should be avoided. In event of inhalation, the victim should be moved to fresh air and oxygen should be administered. In case of ingestion, the victim should be made to consume a copious quantity of milk and water. A medical practitioner should be consulted at once. Personal protective equipment should always be used while handling.
