EC number: 629-765-4
CAS number: 1226892-44-9
are reaction products of fatty acid and polyethyleneamines.
resulting product therefore is a mixture of the amide structure of the
fatty acid and the polyethyleneamine and its imidazoline. Also is
possible that two fatty acid molecules bind at each end of the
polyethyleneamine resulting to di-substituted amine or imidazoline. The
final product is a mixture of these substances, containing amine-,
amide-, and Imidazoline functional groups.
it has been demonstrated that the imidazoline bond is readily
hydrolysed, to re-form the Amidoamine form.
members of this category can be characterised by their starting
materials: the hydrophobic part from fatty acids and the hydrophilic
part from the polyethyleneamines:
Fatty acids (FA):
difference in alkyl chain length distribution is limited among the
members of this category. The majority is C18 unsaturated alkyl.
chain length of the polyethyleneamines used for the production of the
various Amidoamines/imidazolines in this category can vary. In order of
increasing EA length ranging from DETA (diethylenetriamine), TETA
(triethylenetetramine), TEPA (tetraethylenepentamine), PEHA
(pentaethylenehexamine) and higher, generally denoted as
polyethyleneamines (PolyEA). Although some products are derived from the
use of basically one specific polyethyleneamine, often a mixture of polyethyleneamines
of different lengths are used.
All substances within the
AAI group show the same reactive groups, show similar composition with
the length of original polyethyleneamines used for production as biggest
read-across of Phys-Chem properties
Due to the chemical
similarity of the substances in the category, it is considered that the
main factor influencing physical-chemical properties is the molecular
weight of the substance. It is considered that C18 unsaturated fatty acids
reaction products with diethylenetriamine as the smallest molecule
represents the highest volatility and the lowest boiling point, flash
point and self-ignition temperature.
