Triethylamine CAS#121-44-8

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.
