Diethanolamine, generally abbreviated as DEA or DEOA, is
an amoebic admixture with the blueprint HN(CH2CH2OH)2. Pure diethanolamine is a
white solid at allowance temperature, but its addiction to blot baptize and to
supercool beggarly it is generally encountered as a colorless, adhesive liquid.
Diethanolamine is polyfunctional, getting a accessory amine and a diol. Like
added amoebic amines, diethanolamine acts as a anemic base. Reflecting the
hydrophilic appearance of the accessory amine and hydroxyl groups, DEA is acrid
in water. Amides able from DEA are generally aswell hydrophilic. Recently, the
actinic has been classified by the International Agency for Research on Cancer
as "possibly baleful to bodies (Group 2B)".
DEA is acclimated as a surfactant and a bane inhibitor.
It is acclimated to abolish hydrogen sulfide and carbon dioxide from accustomed
gas.
In oil refineries, a DEA in baptize band-aid is
frequently acclimated to abolish hydrogen sulfide from acerb gas. It has an
advantage over a agnate amine ethanolamine in that a college absorption may be
acclimated for the aforementioned bane potential. This allows refiners to
abrade hydrogen sulfide at a lower circulating amine amount with beneath
all-embracing activity usage.
DEA is a actinic feedstock acclimated in the assembly of
morpholine.
