- Ethanolamines were
prepared in 1860 by Wurtz from ethylene chlorohydrin and aqueous
ammonia. It was only toward the end of the 19th century that an
ethanolamine mixture was separated into its mono, di and triethanolamine
components. It was achieved by fractional distillation.
- Ethanolamine, also
called 2-aminoethanol or monoethanolamine (often abbreviated as ETA or
MEA), is an organic chemical compound that is both a primary amine (due
to an amino group in its molecule) and a primary alcohol (due to a
hydroxyl group).
- Ethanolamines, a viscous compound
that smells like ammonia, are commonly found in biological tissues, and
it also has numerous industrial applications.
- Ethanolamine is
commonly called monoethanolamine or MEA in order to be distinguished
from diethanolamine (DEA) and triethanolamine (TEA).
- Ethanolamine is the
second-most-abundant head group for phospholipids, substances found in
biological membranes, and is also
used in messenger molecules such as palmitoylethanolamide which has an
effect on CB1 receptors.
- Monoethanolamine is
produced by reacting ethylene oxide with aqueous ammonia; the reaction
also produces diethanolamine and
triethanolamine.
- Ethanolamine is
widely applied to surfactant, emulsifier, and plasticizer, accelerant,
curing ingredient and vesicant, and it could remove H2S and CO2 from
refinery and natural gas streams. It is also important in the
manufacture of herbicides, detergents, cosmetics, metal cleaners, and
textiles.
- Ethanolamine is often
used for alkalinization of water in steam cycles of power plants,
including nuclear power plants with pressurized water reactors. This
alkalinization is performed to control corrosion of metal components.
- Ethanolamines require
care in handling. Skin or eye contact can result in chemical burns.
Breathing vapors can result in
irritation to the nose or throat. Ethanolamine product handling is
complicated by their tendency to react with many other chemicals. They
will react with carbon dioxide in the air.
- Aqueous solutions of MEA (solutions
of MEA in water) are used as a gas stream scrubbing liquid in amine
treaters. For example, aqueous MEA is used to remove carbon dioxide
(CO2) from flue gas.
- Monaethanolamine in contact with iron
can from an unstable crystalline complex called tris(ethanolamino)-iron.
-
Ethanolamines
consumption in China has been increasing very rapidly in the past few
years with CAGR of 16.2% in 2000-2007.
