Ethanolamines
Monoethanolamine, diethanolamine,
and triethanolamine are amino alcohols which were introduced
industrially about 1928 and have been finding application
in increasing quantities in diverse fields ever since.
Commercial production of ethanolamines
is accomplished by reacting ethylene oxide with ammonia to yield
a mixture of the three compounds. By subjecting
this mixture to a series of separations, monoethanolamine, diethanolamine,
and triethanolamine are obtained. Triethanolamine is offered
commercially in two concentrations,
85 wt. % and 99 wt. %. The 85 wt. % material contains up to
15 wt. % diethanolamine.
Physically, these compounds are
clear, viscous liquids at room temperature and white crystalline
solids when frozen. Diethanolamine has the highest freezing
point of the group, 28.0C, and monoethanolamine the lowest,
10.5C. They all have comparatively high boiling points, although
at elevated temperatures they
are subject to decomposition, particularly diethanolamine.
Their odors are ammonical to varying
degrees, with monoethanolamine being the most marked. The ethanolamines
are hygroscopic and miscible with water,
most alcohols, and polyols. They and their aqueous solutions
are alkaline. Being bifunctional, ethanolamines react with acids
to form esters or salts, and most
of their industrial applications are dependent to some degree
on these features.
Monoethanolamine
(MEA)
A chemical intermediate in the
manufacture of cosmetics, surface-active agents, emulsifiers,
and plasticizing agents; a gas-scrubbing agent for absorption
and removal of H2S and CO2 from refinery and natural gas streams;
carbon dioxide and ammonia manufacturing.
