The versatile family of ethanolamines from Dow – including monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) – offers a broad spectrum of application opportunities.

Because ethanolamines combine the properties of amines and alcohols, they exhibit the unique capability of undergoing reactions common to both groups. As amines, they are mildly alkaline and react with acids to form salts or soaps. As alcohols, they are hygroscopic and can be esterified. The chemical structures of ethanolamines are:


  • DOW MEA is available as MEA, MEA LFG (Low Freeze Grade), MEA Gas Treating grade and MEA ICF (Iron Chloride Free).
  • DOW DEA is available as DEA, DEA gas treating grade and DEA LFG
  • DOW TEA is available as TEA 99%, TEA 99 LFG, TEA Commercial and TEA Commercial LFG
