APPLICATIONS
|
Alkanolamines have the combined physical and chemical characteristics of both
alcohols and amines in one molecule, which makes them useful intermediates in
the synthesis of various target molecules for the use in many diverse areas such
as pharmaceutical, urethane catalysts, coatings, personal care, products, Water
treatments, corrosion inhibitors, and gas treating industries. There are 1°, 2º
or 3º nitrogen atom and one hydroxyl group at least in alkanolamines.
Alkanolamines react with inorganic acids carboxylic acids to form salts, soaps,
esters, or amides. Alkanolamines are used in both water- based and solvent-based
coatings to enhance the solubility, reducibility, pigment dispersing and pH
stability. They are used in cathodic electrodeposition systems and as a catalyst
for chain-extend. Alkanolamines are used to prepare surface-active soaps through
reaction with fatty acids. Surface-active soaps are used commercially as a
emulsifier, lubricants, detergents, pesticides and personal care products.
Alkanolamines maintain a constant alkalinity in the boiling water flows and
condensate not to form solid products which would impede line flow. This
function is applied for corrosion Inhibits. Alkanolamines are widely employed in
the preparation of water soluble cationic flocculants and ion exchange resins
which adsorb solid and colloidal particles by electrostatic attraction. They are
used for water treatment industry. Alkanolamines and their derivatives are
widely used as intermediates for the production of active pharmaceutical
ingredients such as procaine, antihistamines analgesics from
N,N-dimethylethanolamine or N-methyldiethanolamine. Alkanolamines are used to
remove Hydrogen sulfide (H2S) and CO2 gas from gas streams in natural and
refinery gas operations. N-Methylethanolamine,
being
a secondary amine,
has
the highest freezing point of this family at -5 C among
alkanolamines. It reacts with fatty acids in an equimolar
ratio to produce amides and amide esters. N-methylethanolamine
is used to as a catalyst for chain-extend to give high
mole weight polyepoxides with a polyol. It is used as
an intermediate
for textile auxiliaries, coatings, pharmaceuticals (particularly
antihistamines
such as diphenhydramine),
optical brighteners, agrochemicals. |
