product description

Triethylamine (molecular formula: C6H15N), also known as N,N-diethylethylamine, is the simplest homotrisubstituted tertiary amine. It has the typical properties of tertiary amines, including salt formation and oxidation. Triethylamine has no reaction in the Hisberg reaction. It is a colorless to light yellow transparent liquid with a strong ammonia odor and a slight smoke in the air. Boiling point: 89.5℃, relative density (water = 1): 0.70, relative density (air = 1): 3.48, slightly soluble in water, soluble in ethanol and ether. The aqueous solution is alkaline. It is flammable, and its vapor can form an explosive mixture with air, with an explosion limit of 1.2% to 8.0%. It is toxic and highly irritating.

Product Usage

Triethylamine (TEA) is one of the most commonly used organic bases in the chemical industry, valued for its strong alkalinity and liquid state. Its primary application is as an acid acceptor and catalyst in organic synthesis, particularly in the production of pesticides, pharmaceuticals, and synthetic resins. In the foundry industry, it acts as a high-efficiency hardening catalyst for sand cores in the cold-box process. Furthermore, it is a critical raw material for manufacturing quaternary ammonium compounds and serves as a neutralizing agent in the production of water-based coatings and adhesives, enhancing their stability and solubility.
