Features Of Dow DEA Diethanolamine

  1. High-purity diethanolamine with consistent batch-to-batch performance for reliable process control.

  2. Strong hydrogen-bonding capacity enabling effective CO₂ and H₂S removal in gas treating applications.

  3. Low volatility and high boiling point support safe handling and stable formulation integration.

  4. Excellent solubility in water and compatibility with a broad range of surfactants, polymers, and solvents.

  5. Acts as both a tertiary amine and a hydroxyl-functional intermediate, offering dual reactivity in synthesis.

Typical Applications Of Dow DEA Diethanolamine

  1. Amine-based acid gas removal (AGR) in natural gas and refinery off-gas treatment systems.

  2. Corrosion inhibitor component in oilfield production fluids and cooling water formulations.

  3. Raw material for synthesizing ethanolamides, morpholines, and nonionic surfactants.

  4. pH adjuster and foam stabilizer in personal care products including shampoos and body washes.

  5. Chemical intermediate in agrochemical synthesis, particularly for herbicide and fungicide derivatives.
