GENERAL DESCRIPTION & APPLICATIONS
There are three ethanolamines called mono, di and tri-ethanolamine with
formula (CH2CH2OH)NH2, (CH2CH2OH)2NH, and (CH2CH2OH)3N respectively. They
are hygroscopic viscous liquid or semi-solid at room temperature. They are
soluble in water, in alcohol and acetone, insoluble in ether and benzene;
They are corrosive with a characteristic ammonia-like odor. their colors
range from almost colorless to amber depending on purity. These substances
decompose on heating and produce toxic and corrosive gases including
nitrogen oxides. They are medium strongly basic and react with cellulose
nitrate resulting in causing fire and explosion hazard. They react violently
with strong acids and strong oxidants. Ethanolamines are produced from
ethylene oxide reacted with ammonia. The principle product is
monoethanolamine and secondary products of diethanolamine and
triethanolamine are produced since ethylene oxide is reactive. They are the
simplest members of the alkanolamine compounds. They have the physical and
chemical characteristics of both alcohols and amines in one molecule.
Ethanolamines stuctures are widely found in antihistamine drugs. In
industrial field, monoethanolamine is an important raw material in the
production of ethylenediamine. Ethanolamines are used as gas-scrubber in
refinery and natural gas operations. They are widely used in the field of:
* Gas-scrubber
o Natural and refinery gas operations
o Hydrogen sulfide (H2S) and CO2 gas removal
* Textile Operation
o Softeners
o Lubricants
o Dye Leveling Agents
o Dispersants
o Durable Press
o Optical Brighteners
* Surfactants and Metalworking fluids
o Impart alkalinity
o Detergents
o Cosmetic formulations
o Acid neutralization
o Fatty acid soaps
o Emulsifiers
o Corrosion Inhibitors
* Others
o Concrete additives
o Cement admixtrue
o Urethane foams
o Agricultural products
o Photographic chemicals
o Biocides
o Oil well chemicals
o Rubber vulcanization accelerators
o Plasticizers
