Production and uses
The reaction of ethylene oxide with aqueous ammonia first produces ethanolamine:
C2H4O
+ NH3 → H2NCH2CH2OH
which reacts with a second and third equivalent of ethylene oxide to give
DEA and triethanolamine:
C2H4O
+ H2NCH2CH2OH → HN(CH2CH2OH)2
C2H4O
+ HN(CH2CH2OH)2 → N(CH2CH2OH)3
About 300M kg are produced annually in this way. The ratio of the products
can be controlled by changing the stoichiometry of the reactants. DEA is used
as a surfactant and a corrosion inhibitor. It is used to remove hydrogen
sulfide and carbon dioxide from natural gas.
In oil refineries, a DEA in water solution is commonly used to remove hydrogen
sulfide from various process gases. It has an advantage over a similar amine ethanolamine
in that a higher concentration may be used for the same corrosion potential.
This allows refiners to scrub hydrogen sulfide at a lower circulating amine
rate with less overall energy usage.
DEA is a versatile chemical intermediate, principal derivatives include ethyleneimine
and ethylenediamine. Dehydration of DEA with sulfuric acid gives morpholine:
Amides derived from DEA and fatty acids, known as diethanolamides, are amphiphilic.
Commonly used ingredients that may contain DEA
DEA is used in the production of diethanolamides, which are common
ingredients in cosmetics and shampoos added to confer a creamy texture and
foaming action. Consequently, some cosmetics that include diethanolamides as
ingredients may contain traces of DEA. Some of the most commonly used
diethanolamides include:
·
Cocamide DEA
·
DEA-Cetyl Phosphate
·
DEA Oleth-3 Phosphate
·
Lauramide DEA
·
Myristamide DEA
·
Oleamide DEA
·
Triethanolamine
