The organic chemical family known collectively as ethanol amines — or ethanolamines (EOA) — is highly useful to a number of industries because its molecules are both primary amines and alcohols. As amines, ethanolamines share a relation to ammonia — NH3 — but with one or more of the hydrogen atoms replaced by groups of hydrocarbons. As predicted by its chemical makeup, ethanolamines have an odor somewhat like ammonia. However, the larger the amine, the more complex its smell becomes. Other than its distinctive odor, ethanolamines have no color and is a liquid with moderate viscosity.

  • Agriculture: Monoethanolamine used in 1:1 ratio with Boric Acid as a plant supplement. Diethanolamine and Triethanolamine are used to produce herbicides like round-up.
  • Coatings & Construction: To aid in both the quality of cement and the reduction of the energy required to manufacture it, triethanolamine is a popular additive to cement production and grinding enhancers. TEA used to help control the water evaporation rate.
  • Oil & Gas: Monoethanolamine into MEA Triazine, biocide production, Ethanolamines are very effective at removing moisture and other contaminants, like sulfur and CO2, during the production and refinement stages of gas.
  • Personal Care: Both monoethanolamine and diethanolamine are used in the cosmetics and personal care industries, especially in the production of shampoos, soaps, and foaming bath liquids. Triethanolamine is used in the production of shaving crème and gel type hand cleaners.
  • Water Treatment: To prevent the corrosion of components made of metal, ethanolamines are often used to control the pH levels of water in power plants — especially in nuclear power production that uses reactors containing pressurized units of water.

Quick Answers

Ethanolamines exhibit the chemical properties of both alcohols and amines, their uses are widespread. Their amine characteristics make them somewhat alkaline, which is why they form soaps or salts in reaction to acids. At the same time, their qualities as alcohols make them ideal for absorbing moisture and eliminating unwanted water molecule.
