SUGGESTED USES

Agochemicals
Monoethanolamine are used as neutralizer agents for anionic emulsifiers.

Diethanolamine and triethanolamine can be used in the preparation of agricultural compounds obtained from 2,4D acid (2,4 dichloro phenoxiacetic) and diethanolamine can be used in the synthesis of glyphosate.

Treatment of Gases
Ethanolamine can be used to treat natural gas and petroleum residual gas in the absorption of carbon dioxide. In gas systems containing carbon, monoethanolamine can be used as a selective absorber, and plays an important role in the production of ammonia, liquid carbon dioxide can dry ice permitting regeneration in the latter cases.

Other Uses
Monoethanolamine is recommended as a synthesis intermediate for the manufacture of corresponding alkanolamides due to it's reaction with fatty acid or coconut oil. As a consequence of their properties, these products can be used in various industrial segments such as detergents, lubricant oils, products for hygiene and personal care, flotation of minerals, etc.

Ethanolamines can also be used in the formulation of pharmaceutical products, dispersing agents for glues, gums, latex and photographic developers, accelerators of rubber vulcanization, corrosion inhibitors, pH controllers, synthesis intermediates, lacquer, paint, wax and polish wetting agents, polymerizing agents and catalysts for polyurethane resins.

Triethanolamine is recommended as an alkalizing agent for dodecylbenzene sulfonic acid, resulting in the formation of an organic salt that is more soluble in water than sulfonic acid neutralized with sodium hydroxide, promoting the obtainment of liquid detergents for manual dish washing with a lower cloud point and greater stability, making the use of hydro topes such as urea unnecessary.

Triethanolamine can also be used to alkalize long-chain fatty acids such as lauryl, ricinoleic, oleic and stearic acids, forming triethanolaminesoap that is soluble in water with an emulsifying effect in liquid soap-base detergent formulations and in transparent pine oil-based disinfectants, promote a blooming effect when the disinfectant is diluted in water.

Since it is a weak base, Triethanolamine can be used as a neutralizer agent in car wash shampoos, polishing waxes, degreasing non-corrosive detergents, liquid laundry detergents and multiple use cleaners.

Monoethanolamine can also be used as a neutralizer agent in car wash shampoos, degreasers in general, wax removers and as corrosion inhibitors.
