Triethanolamine CAS#102-71-6
Products Description of Triethanolamine CAS#102-71-6
Triethanolamine—also called trihydroxyethylamine or amino triethanol—is a colorless oily liquid with an ammoniacal odor. It readily absorbs moisture and turns brown when exposed to air or light at elevated temperatures. At low temperatures, it forms colorless or pale yellow cubic crystals. Its key physical and chemical properties are as follows: melting point 21.2℃; boiling point 335.4℃ (at standard pressure), 277℃ (19.950 kPa), and 206–207℃ (1.995 kPa); relative density 1.1242; refractive index 1.4852; Kb = 2.5×10⁻¹⁰; pH of 0.1 mol/L aqueous solution is 10.5. It is miscible with water, methanol, and acetone, soluble in benzene and ether, and slightly soluble in carbon tetrachloride and n-heptane. As a strong base, it can combine with protons and is applicable in condensation reactions.
