ETHANOLAMINES (MONOETHANOLAMINE, DIETHALAMINE, TRIETHANOLAMINE)

Amines are organic compounds that contain nitrogen atoms with a lone pair


Basically, they are derived from ammonia (NH3) in which one or more hydrogen atoms is.

Monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) are all ethanolamines[Ethanolamines are a family of chemicals that work as surfactants and emulsifying ingredients in personal care and cleaning products. They are made through a chemical reaction of ethylene oxide with ammonia. Common ethanolamines include monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA).


Here are some things to know about MEA, DEA, and TEA: 

  • Toxicity
    They are toxic, flammable, and corrosive liquids with an ammonia odor. They can irritate the skin, eyes, and respiratory tract, with MEA being the worst irritant. 
  • Applications
    They are found in soaps, shampoos, hair conditioners and dyes, lotions, shaving creams, and more. 
  • Health concerns
    Some studies have linked DEA and TEA to cancer in the liver in female mice. 
  • Avoidance
    Some say that these ingredients offer no benefit to the skin and may cause harm. They recommend reading labels and choosing products that don't contain these ingredients. 

USES:

  • Petroleum gas: Removing hydrogen sulfide and carbon dioxide from petroleum gas streams
  • Emulsion paints: Used in the production of emulsion paints
  • Agricultural chemicals: Used as dispersing agents in agricultural chemicals
  • Carbon dioxide: Used as a precursor in the manufacture of carbon dioxide for soft drinks
  • Pharmaceuticals: Used in the pharmaceutical sector
  • Textiles: Used as textile softening agents 

INDUSTRAIL USES:

In gas treating processes for refineries and natural gas streams, MEA and DEA help remove contaminants from gasoline. As a chemical intermediate, DEA is used in agrochemicals to make pesticides, where it helps increase a pesticide's ability to dissolve in water.

Monoethanolamine (MEA), diethanolamine (DEA), and TEA are alkanolamines that have many industrial uses;


  • Gas treating: MEA and DEA are used to remove contaminants from natural gas and gasoline streams in refineries. 
  • Chemical manufacturing: MEA and DEA are used as chemical intermediates in the production of resins, plasticizers, lubricants, and more. 
  • Agrochemicals: DEA is used in pesticides to help them dissolve in water. 
  • Emulsifiers: MEA and DEA are used in the production of wax, polish, and coating products to help ingredients mix and keep other materials from corroding. 
  • Plasticizers: MEA is used to make plastic more pliable and soft. 
  • Carbon dioxide capture: MEA, DEA, TEA are used in industrial processes to capture carbon dioxide. 

MEA, DEA, and MDEA are volatile, have low thermal stability, and can undergo oxidation processes that form corrosive products. They should be handled carefully and with safety protocols in place. 


PACKING:

MEA:Due to the fact that this compound is liquid at normal temperature and has corrosive properties, MEA chemical compound is supplied in 230 kg PE drums and/or in IBCs (intermediate bulk containers) in order to prevent corrosion challenges. Tanks and barrels for storage of this material can be selected from corrosion-resistant materials if required.


Triethanolamine (TEA) is packaged in jars and drums, and in barrels. The packaging sizes vary, but can include:

50 kg, 200 kg, 220 kg, 230 kg, 210 kg, and 225 kg. 


Diethanolamine (DEA) is often packaged in drums or barrels:


  • Drums: Liquid diethanolamine is often packaged in drums, and can come in a variety of sizes, such as 200 kg and 215 kg. 
  • Barrels: Industrial grade diethanolamine can be packaged in barrels.
