For chemists, formulators, and procurement managers in the chemical industry, a thorough understanding of a compound's properties and synthesis is fundamental. Triethanolamine (TEA), with the CAS number 102-71-6, is a prime example of a chemical whose broad utility stems directly from its molecular structure and synthesis pathway. As a dedicated Triethanolamine manufacturer in China, we are committed to providing insights into this essential compound and ensuring its consistent, high-purity supply.

The Chemistry of Triethanolamine: Structure and Properties

Triethanolamine is an organic compound that is classified as both a tertiary amine and a triol. Its molecular formula is C₆H₁₅NO₃, and it possesses three hydroxyl (-OH) groups and one tertiary amine nitrogen atom. This unique dual functionality dictates its chemical behavior and widespread applicability. Key properties include:

  • Solubility: TEA is highly soluble in water, ethanol, acetone, and glycerin, due to the presence of polar hydroxyl groups that readily form hydrogen bonds. It exhibits lower solubility in non-polar solvents like benzene and carbon tetrachloride.
  • Alkalinity: As a tertiary amine, it is weakly alkaline, capable of neutralizing acids and forming salts.
  • Reactivity: The hydroxyl groups can undergo esterification and etherification reactions, while the amine group can be quaternized or undergo other amine reactions.
  • Appearance: It typically presents as a colorless to pale yellow, viscous liquid.

These inherent chemical characteristics make TEA an excellent choice for applications requiring pH adjustment, emulsification, buffering, and as a precursor for other specialty chemicals.

Synthesis of Triethanolamine

Triethanolamine is primarily synthesized through the reaction of ethylene oxide with aqueous ammonia. This exothermic process results in a mixture of monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA). The ratio of these products can be controlled by adjusting the molar ratio of ammonia to ethylene oxide and reaction conditions such as temperature and pressure. Following the reaction, the different ethanolamines are separated through fractional distillation. Our manufacturing processes are optimized to yield high-purity TEA, ensuring minimal impurities for critical applications.
